Operating System

The best free programs to optimize or repair Windows

The Windows users know well that you must always have an ace up your sleeve, because sometimes the operating system offers us some surprises. Not that Windows has a bad design, fortunately over the years and successive versions of the OS it´s the developers have remedied everything that caused errors to such an extent that currently Microsoft’s operating system is extremely stable and fluid.

But as mentioned, always something can happen, and the aim of this article is to present a number of applications that we can be extremely useful for when Windows it gets moody and stops working properly. Best of all is that the applications mentioned in this article, are totally free, i.e. freeware software, and although in some cases do not include all the features of the paid versions thereof, for the task in which we will use comply perfectly with its mission.

Windows optimize apps

What we will achieve with this software

All these tools enable us reliving a computer that has been infected by viruses or malwares and not booting, recover free space needed for the equipment to function properly, defragment a slow hard drive, manage compressed files and a complete listing all hardware installed on your machine in order to download and install its drivers in case something goes wrong.

Regards to the version of the Windows operating system installed on our PC, it should not be a problem because all the applications mentioned in this article are compatible with earlier and modern versions of the OS, including XP, Vista and Seven.

To consider

An important consideration to take before installing and using these programs is to create a system restore point, as this methodology will allow us to return to a previous instance in case something goes wrong with the operating system or some of the drivers.

In this stage, the restore point system is a really useful when we manipulate files and operating system configurations, as all such recuperation or reparation programs tend to modify or eliminate significant amounts of data, and if not done properly, we can let to Windows unusable.

With this we are not saying that enhancing applications or system repair are dangerous, just that we must use them with caution.

The software

CCleaner

A classic repair system and one of the tools used by computer users around the world. Famous for its qualities, CCleaner has earned its reputation due to its powerful features, among which we mention the possibility of eliminating useless and unnecessary files that the system accumulates through its use, that only takes up space and slow down your system. This includes temporary files, cache browsers that have installed such as Opera or Firefox, Windows registry and much more.

BootMed

A utility designed for extreme cases. BootMed is a boot disk based on the popular Ubuntu Linux distribution that is designed to regain control of a PC with problems in the MBR or who is infected with a virus.

The first thing you need before you start is to clarify that BootMed is not an application for any user, because its use is somewhat difficult, but not impossible to use. If we have some patience, and of course knowledge about what we are doing, we can use it without problems.

BootMed provides a number of tools that will allow us to repair virtually any problem related to the startup of our PC, and it includes a partition manager, an application to remove malware and utilities to recover partitions and solve problems at the start of our PC.

Best of the application, at least for less experienced users, is that the tools offered is an interface similar to a desktop user, which is less traumatic for them.

If you wish, you can download the application from this link.

Smart Defrag

Recently, and based on extensive tests carried out by specialists in the field, it was found that defragment the hard drive of our computer does not improve the performance of the PC as we thought, but still offers tremendous advantages used in other circumstances, such as in the case of accidental file deletion, since a well-ordered hard disk gives us a better chance when trying to recover.

Smart Defrag then becomes a highly recommended utility when it comes to maintaining a disk with a healthy structure, due to the powerful options offered, and among which are remarkable the possibility of a full defragmentation or defrag involving only locate files in more accessible places to the disk reading heads.

7-Zip

While WinRAR appears to be the undisputed leader in the file compression industry, this may well be given due to misinformation basic computer user, which downloads and installs the application without regard to be paid a license for its use, often led by ignorance about other applications that do the same as WinRAR but free.

In this sense, 7-Zip is a powerful tool capable of creating and unzipping compressed files, and also provides us with the ability to encrypt them with the AES method.

The main features of 7-Zip reside basically in full gratuity, speed and the large amount of compressed file formats it can handle.

Windows optimize apps

At this point, 7-Zip can compress and decompress files in 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM format, while only can decompress files ARJ, CAB, CHM, CPIO, CramFS type, DEB, DMG, FAT, HFS, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, SquashFS, UDF, VHD, WIM, XAR and Z. No doubt a ubiquitous application in our arsenal.

How to build a PC: Tools and choice of accessories

No doubt that the assembly of a computer can become one of the most exciting experiences. While it is a complicated process, it is not necessary to be an expert to carry it out, nevertheless clearly that we must carry on with the utmost care. Here we tell you all the steps to achieve it.

There are several reasons why many users choose to build with its hands their own PC. Note that the assembly of a computer is no longer as difficult as it was years ago, so it is a task that anyone can undertake without practically problems.

How to buid a PC

Mounting a PC from scratch brings us a lot of benefits. In principle costs, because the fact is that the construction of our own equipment are significantly cheaper than buying one preassembled. In addition with the same budget we can access a truly superior computer to the offered in the store, and we can even choose to purchase high quality components.

On the other hand, a PC built by us can be easily customizable, upgradeable and even upgradeable, which will bring as many years of life of the equipment. Let’s not forget also, when we assemble our own PC, at the same time we are learning a lot about the hardware.

Very well, if you’ve decided to build your computer, here are some tips and steps to achieve your mission properly.

It is noteworthy that before starting to assemble the team, we must put on an anti-static wrist strap to prevent static electricity discharges on the components, which can irreparably damage the parts of the equipment.

How to buid a PC

We can also discharge any static electricity produced by our body by land, for example, maintaining contact with a metal component cabinet.

Another fundamental aspect is to look after the area in which we will work, since it must be large enough to allow us to move comfortably, and also allow us to place on a flat surface the different elements to be used during assembly. Ideally, work on a wooden surface.

Also is extremely important that before you start assembling a computer, we carefully read all the manuals provided by the manufacturer of each component, so as not to damage them during assembly.

How to buid a PC

The elements used

About the work area must have not only the cabinet and the various internal components that build up the new PC, but also must have available the following items:

  • Multistep screwdrivers and sizes
  • Some additional screws
  • Cleaning cloth
  • Isopropyl Alcohol to clean
  • A small plier long tips
  • A flashlight (optional)

Before starting the assembly, it is advisable to clean the components and the various surfaces of the cabinet with cloth and isopropyl alcohol, to remove any accumulated dust and dirt.

Choice of accessories

Once we have all the essential elements of the future PC, i.e. CPU, Motehrboard, RAM, video card and hard disk, then it is time to start choosing the cabinet or box containing all these elements.

Cabinet

In general, a variety of very good cabinets at very low prices currently on the market, of course we can also choose to purchase a brand known cabinet, but we must bear in mind that when dealing with high-end products, its value will be much higher.

How to buid a PC

It is also important that we choose a cabinet that includes plenty of islands to add several hard drives and optical disk drives, because it is possible that in the future we desire to incorporate more than one of these elements.

With regards to the connectors where we will plug the microphone, headphones and speakers, the ideal is that they are located in the front of the cabinet, as this will give us easier access to switch audio devices.

Choosing optical drive

While the DVD drive is not as important today, as they have been replaced by memory cards and pen drives, is likely that we require a CD/DVD drive to install the programs and the operating system.

By acquiring an optical drive, we can also come to consider buying a modern product that includes Blu-ray technology. While it is true that Blu-ray drives are significantly more expensive than DVD, keep in mind that a unit of this type will be a step further in technology, also it will allow us to play movies and other videos in high definition.

How to buid a PC

It is important to mention that when it comes to external storage, an excellent option is to use memory cards, which although they are more expensive, provide greater physical security to stored content.

In addition we note that today almost all devices we have at home usually include an SD card, so an excellent option is to add to the PC we’re building a 3.5 module with card slots, which can be located in the cabinet spaces available for HD or CD/DVD drives.

The last but not least

It is desirable that in the list of sourcing for our PC we include some more items that will be critical to enjoy the computer. This is where we must choose peripherals and accessories that accompany the computer:

Wi-Fi card or adaptor: We can choose to include in the PC case an Wi-Fi internal board, or add an external device such as dongle. More about that here.

Microphones: According to the use that we think give this peripheral, we can choose to purchase a cheap mic or choose something more expensive that allows us to make high quality recordings. Find more information here.

How to buid a PC

 Speakers: The quality and cost of a pair of speakers depends exclusively on the use we will give, as well as the budget we have available. They are indispensable for videoconferencing, watch videos and play music.

Webcams: is a fundamental device if we use the PC to communicate via video, so we invite you to read more information here.

Another accessory that should not be overlooked is the acquisition of a power stabilizer, as it will help us to protect the computer from fluctuations in the power supply.

How to buid a PC

Finally, and no less important, is to choose the operating system you install on brand new PC. But for this, we must first assemble the team, so get to work!

What are the types of operating systems?

The operating system of a computer is the vital element to work. Without SO, we cannot perform any tasks, which the PC pas to be just a decorative object. Such is the importance of the operating system.

As we know, there are several on the market OS: Linux, Windows, Mac, Android and many more, but these are their trade names. The important thing is what kind of operating system corresponds each. This is the aim of this article.

Operating system types

Today, there are 4 basic types of operating systems. They are divided into groups related to the type of computers that control and the type of applications that execute.

These are the broad categories:

RTOS Real-Time Operating System

It is used to control machinery, scientific instruments and industrial systems. Generally an RTOS has a very simple interface for the user and is not intended for the end user, since the system is delivered as a “sealed box”.

Operating system types

The RTOS function is to control the computer resources for a specific operation, such as execute the same instruction or operation during a determinate time period. In a complex machine, if one part moves faster, because there are resources available to do system, it can be catastrophic.

Single-user, single-tasking

This operating system was developed for a single user can do one thing at a time. Some operating systems used by cell phones are the best example of a modern single-user and single-tasking operating system.

Operating system types

Single-user, multi-tasking

This type of operating system is the most widely used in desktop computers and notebooks. The Microsoft Windows and Apple MacOS platforms are examples of operating systems that allow a single user to use several programs simultaneously. For example, it is perfectly possible for a Windows user to write a note in a word processor while performing a download of a file, or printing a email.

Multi-user, multi-tasking

A multiuser operating system allows multiple users to use the computer’s resources simultaneously. The operating system must ensure that applications for multiple users are balanced. Each of the programs used must have sufficient and separate resources so that a user with problems does not affect to the other users. Unix, Windows Server, VMS and mainframe operating systems like MVS are examples of multi-user operating systems.

Operating system types

It is important to differentiate the multiuser operating systems that support single-user operating systems networks. Some versions of Windows can support multiple users on a network, but the operating systems themselves are not true multi-user systems. The system administrator is the only “user”. The network supports and all remote users are, from the standpoint of the operating system, a program being executed by the administrator.

You need to do an operating system?

The aim of an operating system is to make that the computer and its peripherals can be used without problems for anyone, even without knowledge of the hardware available on that computer.

It has to enable the user to create and access files, use the programs, enter internet, play and all things that can be done with computers or mobile devices. Besides that, the operating system has to execute the software and provide access to the system resources to user in a simple and organized way.

Operating system types

What is the most used operating system?

Undoubtedly, Windows, the operating system of Microsoft, is the most widely used. It is present in over 90% of the world’s computers.

What is the difference between a 32 bit and 64-bit PC?

One of the questions often ask those who have to change a computer, or doing installations or upgrades to the operating system or software user, is about the type of architecture that runs internally equipment. We have surely heard about if a processor or operating system version is 32 or 64 bits, but unfortunately these numbers mean nothing to us.

This is precisely the objective of this article, provide information on this subject so we can all know exactly are related to these figures and what its practical applications for daily work, since a wrong implementation of any of these platforms in certain tasks may result in a waste of money or even in a major loss of productivity.

Differences between 32 and 64 bits

Before starting

As a first step, it should be noted that the terminology “PC 32 or 64 bits” refers to both the processor architecture and operating system used to process the data, i.e. both things go hand in hand, at least in most the cases. That said, we started the full article.

Main differences between 32- and 64-bit

Basically, the main difference between a 32-bit processor and a 64-bit processor is that the first is able to process bit sequences up to 32 bit, while 64-bit processors may extend to twice this capacity.

As we know, a PC processor is responsible for conducting all logical and mathematical calculations to get the results requested by the user, and thus must manage information packets at a certain rate.

At this point the main difference between both platforms is that in the case of 64-bit processors, these can work with twice the information in the same clock cycle that a processor of 32 bits, allowing them can access higher capacity memory and process much larger blocks of data, increasing by this way the performance and speed of the overall process.

Differences between 32 and 64 bits

Another difference, and why many professional systems prefer a 64-bit architecture, is that this type of processors can address theoretically up to 16 exabytes of memory while the 32-bit processors can only address 4Gb, more than enough amount of RAM for desktop computers in an office, but for more complex systems is a too low amount of memory.

As for Windows operating systems, the most important difference between versions 32 and 64 bits is that the first supports up to 4Gb of RAM, but which can only be used 3.25 Gb. In the case of 64-bit operating systems, can address up to 192 Gb of RAM.

A stark choice: What PC must I buy? A computer of 32 bits or one of 64 bits?

The first thing to think about when evaluating the purchase of a PC, especially if you are in doubt about which of the available PC architectures choose, is what is the use that will give the new computer.

In the event that only we use for common tasks in home or office, i.e. surfing the net, reading mail, making spreadsheets or write a document, a computer and operating system with a 32-bit architecture is enough because we should not subject the equipment to very complex tasks.

Differences between 32 and 64 bits

In addition the processing capacity of a 64-bit system costs a lot more money, and if we will not need this extra capacity, is useless to spend the extra cost of this type of 64-bit architectures to waste it.

Now, if we are professionals in some specialized area as the graphic design, architecture, engineering, video editing or other contexts where it is necessary more computing capacity beyond the usual, then the best choice is to have a 64-bit system, since this architecture can work with larger and complex numerical operations than a 32-bit system, type of architecture that will have to split the operations and instructions in various sequences, subtracting performance and capacity system-wide calculations, which does not happen in a 64-bit architecture, since is able to process more number of operations at the same time, making it much more stable and faster to the whole.

Differences between 32 and 64 bits

Migrating from a 32-bit to a 64-bit

If we are evaluating the possibility to migrate from a 32-bit system to a 64-bit, one of the first things we have to think about is in the software compatibility, i.e. programs and hardware drivers. It is extremely important that before starting with migration we are very sure that all our hardware such as cameras, scanners, printers and everything else, have a 64-bit version of its drivers. Otherwise, if you do not want to complicate, will touch go buy new hardware.

If we take into consideration the warnings of Microsoft on this point, install a hardware controller of 32-bit in a 64-bit version of the operating system, may result in errors or until even the device does not work. In the case of user programs, a software developed for a 32-bit platform can function normally on a 64-bit OS, but we will not have that extra capacity provided by these systems.

Differences between 32 and 64 bits

Fortunately, most programs, at least the best known, offers versions for 64-bit platforms, which has also allowed the expansion of this type of architecture, the same happens with the leading manufacturers and device drivers.

Another thing we have to consider is that if we want to migrate to a 64-bit architecture from a version of Windows 32 bits, it cannot be done by an upgrade or patch, will have to buy a specific version for that architecture. Of course if you use a free operating system like Debian or its derivatives like Ubuntu, migration not be a problem.

Conclusion

As we have seen, a 64-bit computer can be the ideal solution for all users that manipulate large amounts of data because of the way this architecture processes information.

Now, if we are users who only use the computer to perform basic tasks and little more, and never demand the computer with things too complex, a 32-bit is the answer to our needs, what also liberates us of a series of problems as the mentioned incompatibility of controllers and software.

In short, if you do not take advantage the benefits of 64-bit, spending it means to have this platform will not be justified in any way.

Software types

There is no doubt that the key part of any computer system is the software, also called program or application, which together with the hardware, are the backbone of any computer or computer system such as desktop PCs, netbooks, smartphones, notebooks or tablets.

Without these programs and codes, the computer would just be a device that is not able to do anything himself except decorate a desk. This article will try to make a review of the different types of programs and applications that can be found in the market.

Software types

In the market, there are many types of software, each developed for a specific purpose, and over the years has established a categorization that defines the task it performs. From here we know how different types of programs and some examples of popular applications differ.

Operating systems

This type of software controls the computer, and without it, the PC is not able to interpret the actions that we request, for example cut, copy or paste. The most important examples of operating systems are Microsoft Windows, in any version, such as Windows XP, Windows Vista, Windows 7 or Windows 8, Apple MacOS or Linux on your different flavors such as Mandriva, Ubuntu, Kubuntu and Debian, just to name the most important.

Software types

However, not only exist the development of operating systems to computers, but also the development of operating systems for other types of devices such as smartphones, smartwatches and tablets. The best examples are Symbian, Android, iOS, Windows Phone and BlackBerry OS, among others.

Text processors

This type of software replaced to the obsolete typewriter, with many advantages. By using a word processor you can edit and write text such as memorandums, letters, contracts, reports, general correspondence, budgets and others documents in a way that could not even imagine a few years ago. It is even possible to send the document you just wrote via e-mail, without having to exit the application.

Software types

With a word processor, you can use various resources for the composition of a document such as underline, bold, special fonts of various types, colors, spell checking, inserting text, images, tables, and many other options that will achieve a professional aspect to our writing. The most cited word processing examples are Microsoft Word, Writer, part of office suite Libre Office, WordPad, Abiword or KWord, just to name a few examples.

Spreadsheets

These types of applications are used to do all sorts of calculations and mathematical operations, being quite useful for various applications such as accounting, accounts payable and receivable, statistical calculations, balances, statistical graphs and many other possibilities for the field accounting in the company or home. Examples are Microsoft Excel, Lotus and Office Calc.

Software types

Databases

These programs are used to store information such as customer’s registration, suppliers, materials, products, for the purpose of being able to have effective monitoring of stocks or movements of any kind. The most important applications of this field are Microsoft Access, Foxpro and Office Base.

CAD programs

CAD (Computer Aided Design), refers to programs of computer-aided design that are widely used by architects, engineers, designers and all professionals engaged in the preparation of plans of any kind.

Software types

Widely used in architecture, engineering and electronics among others. The most significant example of this category is the company Autodesk AutoCAD, but we also have Blender, open source and free.

Graphic design

Such programs are regularly used in any graphic design studio where magazines, books, and all kinds of printed material consisting. Basically they can be divided into two types: Composition and retouching & image manipulation.

The most commonly used in this field are software like Adobe Illustrator, Adobe InDesign, Adobe Photoshop, and is also used, but to a lesser extent CorelDraw! and Corel Photo Paint, among others.

Software types

However, these programs are not all that is needed in this area, because we also need additional software as font managers, catalogers images and PDF converters, among others.

It should be noted that there is also a free software of this type, such as The Gimp.

Suites

Such programs tend to integrate multiple applications that fulfill a different function in one package. The most popular suites are Microsoft Office, Open Office or Adobe Suite. The first two options are focused in integrate work such as word processing, spreadsheet and other in a one package, while the third is aimed to the professional graphic field.

Browsers

Perhaps one of the most used programs today, given the unstoppable fury of the Internet and social networks. These programs serve to connect and navigate through Internet. The most popular browsers are Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Safari and Opera. It should be noted that they are all free programs.

Software types

Applications for Smartphones

A special category of software programs are exclusively designed for operating systems included in current smartphones.

In the market there are several operating systems for mobile phones, as we saw above, but unfortunately the software developed for these different platforms are not compatible. This means that an app that runs on iOS will not work on Android, and vice versa.

Software types

These apps, also known as software for smart phones, offer the user a very important range of possibilities, because with them can count on help for any kind of task you want to take with your phone.

For this there are in the market for office applications, mail readers, games and many others, it is only a matter of looking in official stores of each operating system and select the one that suits us.

IPhone iOS or Android, which is better?

Many people are faced with a problem when choosing a smartphone, especially the wealth of information that can be found on the operating systems of these phones, most often confuses users with many facts and figures. The prestigious Apple, has its own operating system, iOS, and like any Apple product, offers quality and reliability, but what happening with Android?

Some say it is the best operating system for smart phones today, mainly because of its performance and characteristics. Both operating systems promise and ensure smooth functioning of devices. But, do you choose? IOS or Android?

iPhone vs. Android

Both seem to be the same thing, however, are quite different. In this article we will review the main differences between the two mobile operating systems, so we can choose between them in the right way.

As mentioned, smartphones running Android and iOS have many differences, and each has its advantages and disadvantages.

Advantages of smartphones with iOS on smartphones with Android

Display and Design

One of the salient features of the iPhone is undoubtedly the Retina Display. Despite not being one of the largest in the market, it is certainly the best image quality and resolution. Furthermore, the design and construction of the iPhone are superior to that of any smartphone with Android.

iPhone vs. Android

Facetime

One of the most interesting features of the iPhone is FaceTime, which allows video calls from one iPhone to another or from an iPhone to a Mac. Although there are hundreds of Android smartphone models that offer two cameras, the fact that at this point is the software that makes the difference in quality of service.

Applications

In this regard, both platforms have hundreds of thousands of high quality applications ready to be installed on the device, the only difference occurs in the stores, where Android offers many more free apps.

A good example of the quality of the software developed by Apple is iTunes media player.

iPhone vs. Android

Advantages of Android on IOS

IPhone users always have the latest version of the operating system through constant automatic update. For Android, there is only the fragmentation of the system and the update depends solely on the manufacturer. Although this point is being resolved with the latest versions of Android that have been released to the market.

Variety of Equipment

There is no doubt that one of the most important advantages of Android is in the variety of devices on which it is installed, allowing us the possibility to choose between different smartphones, as they are increasingly available on the market. In this sense, there is only one type of iPhone, just with a few variations, limiting the choice.

iPhone vs. Android

HD Videos

Another advantage of Android is the ability to play videos in high definition on a screen or TV, through the HDMI ports included with some smartphone models.

The iPhone, in addition to not have this port, has no memory card slot, which most Android devices have for expand store capacity by simply adding a microSD card.

iPhone vs. Android

Powerful processors

Regarding processors (CPU) that currently have smartphones with Android or IOS, virtually no differences, since both types of chips are powerful, offering excellent performance that allows them to perform any task.

Now it’s up to you to choose … iOS or Android?

Give us your opinion at the bottom of this page!

Which it is the operating system?

An operating system can be defined as a set of software specially developed for the execution of various tasks, being as a intermediary between the user and the computer.

This set of programs manages the hardware of a computer or other electronic device, providing basic routines for controlling the various devices and expansion cards of the computer and it allows manage, scale and perform interaction tasks.

An operating system also has the function of control all the peripherals of a computer. It is responsible for maintaining the integrity of the system. We can say that the operating system is the most important software on your computer.

Wich is the Operating System

There are many types of operating systems, whose complexity varies depending on what type of functions can provide, and on what kind of equipment can be installed. Some operating systems allow you to manage large numbers of users, but others control hardware devices such as CNC machines.

When the operating system starts running, then performs the processes that will need to function properly. These processes can be files that need to be frequently updated, or processing of useful data flow. You can have access to different operating system processes through the Task Manager, where can see all the processes that run the operating system from the boot to its present state is.

One of the functions of the operating system is the load into memory of the user programs, so they can be executed easily. When a program is running, the operating system continues working. For example, many programs need to access to the keyboard, video, and printer, plus disk access to read and write files.

Wich is the Operating System

All these accesses are performed by the operating system, which is active throughout the time, serving the programs being executed.

The operating system also manage the computer resources, in order to avoid conflicts. For example, the operating system prevents two programs simultaneously access the same memory sector, which could cause problems. The operating system works as a conductor, ensuring that all programs and all computer components work harmoniously.

Operating System Functions

The operating system is a set of programs that perform specific task:

  • Initializes the computer hardware
  • Provides basic routines to control devices
  • Manages different tasks
  • It maintains system integrity

A very simple operating system, to control a security system, por example, may be stored in a ROM (Read Only Memory), a chip that holds the instructions for the device, and take control when connected to the computer.

Wich is the Operating System

The first task would be reset (and probably testing) hardware sensors and alarms, and then activate a routine that “listens” continuously all system sensors. If the status of any sensor input changes, a routine alarm would be activated.

In a large multi-server system, with many computers connected to it, the operating system is much more complex, as it has to manage and execute all orders of users and ensure they do not interfere with each other.

In addition have to sharing all serial devices that they are the same type (equipment that can only be used by one user at a time, such as printers and disks) among all users who requiring use these services. The operating system can be stored on a disk, and certain parts of it are loaded into the computer’s memory (RAM) when necessary.

The operating system provides utilities to:

  • Users document and files management
  • Controlled Program Execution
  • Communication between users and other computers
  • Administration user fee for storage space and process

It is also necessary that the operating system present to the user an interface from which to accept, interpret and execute commands or programs. This interface is normally is called  shell or command line interpreter (CLI). In some systems it could be a simple line of text using keywords; in other systems could be graphical, using windows and a pointing device like a mouse.

The different parts of an operating system

The operating system of a computer that is used by many people at the same time, it is a complex system. It contains millions of lines of instructions written by programmers. To write an operating system more easily, they are constructed as a set of modules, being each responsible for performing a specific task. Typical modules in a large multiuser operating system usually are:

  • Kernel
  • Process Manager
  • Scheduler
  • File manager

The Core-Real Time Execution

The kernel of an operating system is sometimes called real-time execution. Some of the functions performed are:

  • Exchange between programs
  • Control and programming hardware devices
  • Memory Management
  • Process Management
  • Scheduling task
  • Interprocess communication
  • Processing of exceptions and interrupts

Our simple security monitoring system (seen above) does not have all the mentioned functions, and would probably be a mono-task system, running only one program.

Therefore, no need to manage changes between more than one program or allow communication between programs (interprocess communication). The memory management would be unnecessary, since the program permanently reside in ROM or EPROM (a special form of programmable ROM).

An operating system developed to manage large numbers of users need a core to execute all the functions described. The user programs are generally stored on disk and need to be loaded into memory before being executed.

This raises the need to manage memory, and the memory of the computer need to be explored to find an empty area to load a user program in it. When the user ends the execution of the program, the memory used for this program needs to be released and made available to another user upon request.

Programming a computer

Basically, a program is a sequence of instructions that will be introduced to the computer to perform a task, so depending on the complexity of the software developed by the programmer, these instruction sets can be incredibly long. These instructions are translated and then be interpreted by the operating system.

In the case of operating systems, there is no talk of programs, but of processes. In modern operating systems, only a portion of a program is loaded at every moment. The rest of the program waits in a drive until needed it. This lets saves memory space.

The computer programs are executed by processors. A processor is a computer chip that executes program instructions. The processors execute millions of instructions per second.

The computer programs are executed by CPU. A CPU is a processor chip that executes program instructions. These CPUs execute millions of instructions per second.

A Process

A process or task is a portion of a program at some stage of execution. A program may consist of several tasks, each with its own process, or functioning as a unit (perhaps communicating with each other periodically).

The Thread

A thread is a separate part of a process. A process may consist of several threads, each of which is separately executed. For example, a thread could perform the graphics refresh of the screen, another thread is responsible for the printing processes, another thread would handle the mouse and keyboard. This provides good response times for complex programs. Windows Server is an example of an operating system that supports multi-thread.

Wich is the Operating System

Multithreaded operating systems

Some systems run only a single process, other systems can run multiple processes simultaneously. Most computers are based on a single processor, and a processor can execute only one instruction at a time. Therefore, as is possible for a single processor to execute multiple processes?

The short answer, it does not thereby. The processor executes a process for a small period of time, and then moves to the next process and so continuously. As the processor executes millions of instructions per second, it seem that many processes are running at the same time.

Wich is the Operating System

In an operating system that supports more than one process at a time, some mechanism must be used to intersperse tasks. There are two ways to perform this change:

Cooperative scheduling: Indicates that a task currently being executed, sometime voluntarily quit the processor and allows other processes are executed.

Scheduling by Priorities: means that a current task is interrupted and the processor is dedicated to another process in standby.

The problem of Cooperative sxheduling is that the process could take a long time to complete, and so refuse to execute other processes. An example of a system of cooperation is the Windows 16-bit OS.

Wich is the Operating System

The Scheduling by Priorities system is better. It provides answers to all processes and helps prevent the crash of equipment. Windows Server is an example of such operating system.

Scheduling

The decision of what the next process to be executed is called scheduling, and can be done in a variety of ways. The Cooperative Scheduling system is usually very simple, since the processes are arranged in a circular row called round robin. When the current process is finished, it moves to the end of the row. The process that is first in line is executed, and all processes move one position on the row. While this is a good alternative, the truth is that it does not prevent a process from monopolizing the system.

The Scheduling by Priority system uses a real time clock that generates an interrupt at regular intervals (say, every 1/100 of a second). Each time an interrupt occurs, the processor start another task. Operating systems generally use such scheduling attributed priorities to each process, so that some may be performed more frequently than others.

Wich is the Operating System

Load the Operating System

The operating system can be loaded into the memory of a computer in two ways.

  • It is already present in ROM
  • It is loaded from disk when the computer is turned on.

If the OS is already present in ROM (like systems of industrial controllers and other machines), take immediate control of the processor when power on.

In more complex systems, the operating system is typically stored on a secondary drive (like a disk), and is loaded into RAM when the computer is turned on. The advantage of such systems is that the scheduling is easier to perform.

The Bootstrap Process

Basically, the bootstrap process is the initial load of the operating system from disk to the RAM. A little routine stored in ROM, called bootstrap loader, or IPL (Initial Program Loader), read a special bootstrap disk. In disc-based systems, this routine typically residing in the track 00, area 00 (or 01), and is called boot sector. The code contained in that sector is transferred to the RAM, and then is executed. It has the sole responsibility of loading the rest of the operating system into memory. Processing different types of operating systems

The different types of operating systems processing

Operating systems are divided into categories that define its characteristics. The operating systems can use combinations of the categories described below.

BATCH

Older operating systems only allow a program to run at a time. The program loaded into the computer runs to completion. The data used by the program can not be changed while the program is being executed. Any error in the program or data means starting all over again.

Wich is the Operating System

INTERACTIVE

These allow for modification and input data during program execution.

SHARING/MULTI-USER

These operating systems share the computer between more than one user, and adopts techniques for scaling priorities.

MULTI-TASK

More than one process can be executed concurrently. The processor quickly staggered between processes. A user may have more of a process executed each time.

Wich is the Operating System

REAL TIME

Basically, a real-time computer system has been described as one which controls an environment by receiving data, the processing of these data, and their return to the starting point, sufficiently fast to affect the environment at that time.

MULTI-PROCESSING

A computer that has more than one processor dedicated to running processes.

The most popular operating systems

Without doubt, the most popular operating system is Windows, developed by the company Microsoft.

The most popular operating systems:

  • Microsoft Windows (for computers)
  • Windows Server (for servers)
  • Linux (for computers and servers)
  • Mac OS (for computers)
  • Chrome OS (for computers)
  • Android (smartphone)
  • Windows Phone (Smartphone)
  • IOS (for smartphones)
  • BlackBerry OS (for smartphones)

Which it is a Internet Operating System?

When we ask what kind of application most used today, no doubt the answer is the web browser. This indicates that the current DOS (acronym that determines the type of operating system that is currently used as a “disk operating system”, will be replaced by the operating system of the Internet, where everything depends of the called “Cloud”.

The first objection to this change could have been the fact that the Internet in general is usually slower than the traditional storage, however, this changed, since modern connections allow stable and fast access to data.

What are the benefits of the Internet Operating Systems?

All applications rely on the Internet, therefore, do not need to download and install any program, or if needed, installation is really simple. The software update is automatic, ensuring that the software is constantly updated. By clicking “Save” the data is also stored on a web server. Many experts speculate that this will bring security and privacy issues.

However, these concerns are gradually forgetting. The advantage is that Internet Operating System will have the same “face” on any place from which it was accessed. The user will have the same desk at home and at work, with all your settings, bookmarks, programs and documents accessible in every place that has Internet access.

A clear example is the web www.protopage.com, which allows us to create a “home page” with notes and bookmarks accessible from anywhere. Protopage provides a desktop with windows and even a ‘wallpaper’ that can be changed according to your taste.

Currently, one of the best examples of Internet-based operating systems is undoubtedly Google Chrome OS, a truly fascinating tool, as it achieves the perfect balance between processing speed, versatility and productivity.
