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.

Windows optimize apps

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


A classic repair system and one of the tools used by computer users around the world.

The basic computer components

Basically, a computer is composed of two fundamental components, which complement each other, and that might not work without each other’s presence.

These two elements are the Hardware and Software, and is the purpose of this article analyze the most important differences between them. Let’s begin.

Computer components


The computer hardware can be defined as all physical parts or materials that can see and touch. For example, the monitor, keyboard, mouse, hard disk, case memory, screws, plastics and other physical parts. That is, the device itself with its internal and external parts.

We could simply define the computer as a box to which a number of devices are connected, also known as “peripherals” used to enter and retrieve information. The case to which we refer is the brain of the computer and is where the information is processed.

Computer components


In very general terms we could understand the software such as “set of instructions that computers use to manipulate and process data”.

Without the software, the computer would be a set of devices without any usefulness, as would our body without a brain to tell him what to do with arms, legs, mouth, etc.

The system software such as operating systems are programs that allow information processed by the production or application software are transformed into understandable instructions for the hardware components. That is, its function is to communicate Hardware elements with various programs we use to perform specific tasks.

Computer components

Some of the most widely used operating systems today are:

  • Windows
  • Linux
  • Mac OS
  • Android

Productivity software

The productivity software are packages of orders and instructions that it serving a particular function or task as, for example, processing a text, perform mathematical calculations, process and view images and videos and surf the Internet, among any others tasks.

Computer components

Some of the widely used productivity software today are:

  • Internet Browsers (Microsoft Edge, Mozilla Firefox, Google Chorme, Opera and others)
  • Word processing (Word, OpenOffice Writer, etc.)
  • Worksheets (Microsoft Excel, Google Sheets, etc.)
  • Presentations (Power Point and others)

What is the Chipset?

Most likely is that we have heard the “Chipset” word countless times, and most users know that it is an essential component that is hosted on the motherboard of our PC. However, it may be that we ignore how this little device soldered to the motherboard works or what its real importance in the hardware of the PC. In this article we will disclose it.

For those who still not know the meaning of the word “chipset“, basically is a group of integrated circuits that are welded to the board of the motherboard.

What is the chipset

What is your function?

The chipset is responsible for filing the correct connection between the motherboard and various essential components of the PC, such as the processor, video cards, RAM and ROM memories, among others.

For this reason, the existence of the chipset is essential for that our computer to work, since it is responsible for sending orders between the motherboard and processor, so that both components can achieve work with harmony.

In short, it is this small element that allows the motherboard is the backbone of the entire system of hardware of our PC, and allows constant communication between various components, through the use of buses.

In the other hand, the chipset has a direct and permanent communication with the processor, and is responsible for managing the information going in and out through the main processor bus. Even their role extends to the RAM and ROM memory and video cards.

What is the chipset

In order to allow the motherboard to interface with the main components of the PC through the chipset, this element is usually made based on standard interfaces that can provide support to various devices of different brands.

PC Chips

In the early use of the word chipset, when old computers Commodore 64 and Atari 8-bit is used, the motherboard available a single chip that had been designed exclusively for that platform, so it did not provide adequate support for components.

Over the years, and after the great advances in the field of computers, motherboards began to include many chips, each with a different function, and providing adequate support for all types of components.

This multitude of chips not only handle interconnect the motherboard with the processor and memory, but also communicate various elements of the PC, to perform control mass storage drives, sound, graphics, plus any other boards.

What is the chipset

Incorporating all these chips into the motherboard has resulted in a great benefit to the operation of the equipment, as when dealing with certain control tasks and process management allows the motherboard is free to perform other tasks .

Currently, there are two types of chipset: the Northbridge and Southbridge called that not only are characterized by being located on opposite ends of the motherboard, but it also ordered to perform different tasks.

The Northbridge

The Northbridge chip is the responsible for interfacing the microprocessor and RAM, controlling all access tasks between these elements and the PCI and AGP ports. At the same time, the Northbridge maintains a permanent communication with the Southbridge.


The Southbridge chip is the responsible for communicating the processor with all peripherals connected to the computer.

What is the chipset

Also, its function also resides in controlling the various devices that are associated with the motherboard such as USB ports, floppy drive, optical drives, hard drives, and so on.

Despite the vital importance of having the chipset on the motherboard in the correct operation of the PC, the fact is that for years has been one of the least important elements, when in fact the chipset usually determine the characteristics of many models motherboards sold in the market today.

What is the chipset

Today, the most important chipset manufacturers are Intel, NVIDIA, Silicon Integrated Systems, AMD, ATI Technologies and VIA Technologies.

Inkjet Printers

The ink jet printers are one of the most widely worldwide used printing technologies thanks to its flexibility, performance and low operating cost and end user price.

These characteristics determine that these devices are present in all areas where there is a computer, both at home and in the office and industry. This article looks at the basics of its operation.

Inkjet printers

The printers use inkjet systems are equipped with a print head with tiny holes throwing ink drops, led by a program that determines how many ink drops and when should be released.


The mixture is important for the formation of color, and it is why color ink jet cartridges usually have three colors (cyan, magenta and yellow) besides black, forming all colors from the mixture of these four inks.

The photo-quality printers can work with up to 12 colors (light magenta, cyan, light black, dark blue, orange, red and green among others) to achieve greater fidelity in color gradations. The fidelity of the image depends the technology used and the quality of the ink.


Bubble jet or thermal

In this technology, the printer heats small amounts of ink at a temperature of about 500° C. With warming a bubble is formed and forces ink droplets leaving the nozzles. The process takes about 20 millionths for each drop formed.

That is the system used by manufacturers such as Hewlett-Packard, Lexmark, Xerox and Canon. The mechanism is in the ink cartridge, making the value of the cartridge is more expensive, but less maintenance and use of all content, because it is under pressure. The resolution is good, and has an optimal cost / benefit ratio.

Inkjet printers


System used by Epson, uses a piezoelectric crystal that changes shape with electricity. Thus, the crystal generates sufficient pressure to expel a small drop of ink, very small, reaching very high resolutions, with almost imperceptible gradations of color.

The printing mechanism is in the printer cartridges, being the cartridges just ink reserves, but with an ink flow based on suction. This system accept dye inks or pigmented base. Its resolution is optimal, but has the disadvantage that the heads may become blocked if that is not used regularly.

Ink Types

Base Colorant

They are soluble molecules in a base colored ink forming a true solution, completely homogeneous and stable. They are fairly inexpensive, and are used both as original cartridges recharged, its durability is average and it is not waterproof.

Inkjet printers


Are insoluble colored particles that are dispersed, usually by additives, so that they remain almost stabilized and homogeneous suspension. Epson and other manufacturers to use in their original cartridges.

The definition of colors is greater than the dye ink, and also durability, used papers with good quality becomes higher the 10 years.

Because of its high degree of water resistance, it is also used in transfer papers, widely used for printing t-shirts, shirts and other fabrics.

Differences between Free Software and Commercial Software

Differentiate the hardware from software is not difficult. In the first classes of any school where it teaches computing, it quickly learns the difference between the two.

Nevertheless, the concept of software is more complicated to understand, despite being widely used and often illegally. An important point to differentiate are the concepts of Free Software and Commercial Software.

Free and commercial software

Free software

The Free software are those software that are under a free license, whereby the use, modification and distribution are permitted at all. The main free software licenses are GPL and LGPL.

The first, intended for users who may incorporate modifications or free software can add to a job, which should make it available also with the same license. The second It is more permissive, and it can be used even for commercial purposes.

Free and commercial software

Free software does not necessarily mean it is free of charge, this is an important point to consider, many free software can be sold separated or incorporated to another software to selling like consulting or related services, for example.

Examples of Free Software:

  • Linux Operating System
  • Java and PHP languages
  • MySQL Database
  • Open Office Suite

Commercial software

Commercial Software or proprietary software is those software that has an owner of its copyrights, and their use is allowed through a business license and most of the time paid.

Commercial software is no different from any other product commercially, only considering that still paying for software will be receiving only license or right to use and will not be buying the software itself.

Free and commercial software

The most important market Commercial Software companies are Microsoft, Google Adobe, Corel, Autodesk and Apple, among many others.

Examples of Commercial Software:

  • Windows operating system
  • Microsoft Office Suite (Word, Excel, Power Point)
  • Adobe Photoshop, an image processing software very popular
  • Suite development for Dreamweaver, Flash and Fireworks
  • Software for vector graphic design Corel Draw

Which one to use? Free Software or Commercial Software?

Using Free Software and Commercial Software is a decision of each company or person. The price, license, business model, support and functionality are some points that should be considered.

Free and commercial software

Many individuals and companies make joint use of Free Software and Commercial Software. It is a good strategy because this way you can exploit the best of both.

What is DNS

The DNS system, more commonly known as Domain Name System is basically responsible for translating the complicated series of numbers that make up an IP address in words that the user can easily remember.

Each web page is accessed by an IP address. The problem is that there are so many that it is virtually impossible to remember the IP address of each. Imagine that instead of introducing “” would have to enter in the browser an address like “”. It would be a very complex task enter the IP of each of the pages, an almost impossible task.

What is DNS

To solve this problem the DNS is used. This allows the use of names (also called domains) instead of IP for access to websites. Basically, in the Internet, the DNS is a set of large distributed databases on servers around the world that indicate what IP is associated with a name (i.e., an address of type

How does it work the DNS system

Internet DNS services are a set of databases on servers scattered around the world. These databases have the function of indicating the IP that is associated with a name of a website. When you enter an address in the search, for example,, the computer asks the DNS servers of the ISP you find the IP address associated with If the servers do not have that information, starts a search with other servers that may have that data.

What is DNS

Root server

To better understand the DNS, go to the following example: Suppose you access the website For this, the server verifies and directed towards the completion .com server, which in turn redirects the server to register the domain, which reports what the IP, that is, the server where it is located the web.

DNS Cache

Suppose you access a website that has not been located by your DNS service provider, so you had to do a search on other DNS servers (through the hierarchical search).

To prevent that search to be performed again when another provider user tries to access the same web, DNS service stores information for the first consultation.

Thus, when another request arises, the server will have already stored the IP belonging to that site. This procedure is known as “DNS cache”.

What is DNS

The Cache information is stored for a certain period of time through a parameter known for TTL (Time-To-Live). This is used to prevent the stored information is updated. The period of time varies according to the server TTL and your manager.


The use of the DNS is not limited to Internet. That resource can (and is) also used in local networks. Its implementation can be made in virtually any operating system and is very common in the Unix and Windows systems.

The Cellphone

Cell phones are so called because the physical area basically covering are a formatted cells. The origin of the cell phone is said that was way back in 1973 when the electronics company consumer Motorola launched the first portable cell phone, which was marketed under the name of Motorola DynaTAC 8000X.

Currently, the number of cell phone models entering the market is almost incalculable, and its sales generates hundreds of billions of dollars a year, so today is considered as the most used electronic device in the world.

The Cellphone

As we can see in any city or town, it is almost impossible to find a person without a cell phone or smartphone in hand, such is the degree of penetration that this device has reached between us, and it is no wonder, because thanks to the tasks which he is able to meet, and the number of important built in functions, we can improve our lifestyle, increasing our productivity and reducing times.

This last decade has seen the birth of the smartphone as we know it today, mixing computer and cell phone offers features with which we could not even dream at the time that was fashionable the Nokia 3210, for example.

But to know more about the smartphone and technology, click on this link.

What hardware integrates a cell phone?

The parts of a traditional cell phone are:

  • Circuit board
  • Antenna
  • Keyboard
  • LCD Screen (Liquid Crystal Display)
  • Battery
  • Microphone
  • Speaker

The Cellphone

Functions of a cell phone

Cell phones have a variety of functions. To name a few, depending on the type of cell phone:

  • Store contact information
  • Manage an agenda of commitments to date
  • Send and receive e-mails
  • 3d games
  • Send and receive text messages
  • Surf websites
  • Play mp3 and other audio formats
  • Play video and TV online
  • GPS service and maps of most cities in the world
  • Integration with other devices such as GPS receiver

How a cell phone works?

Cell phones, operating on radio frequency, innovated to minimize the availability of RF spectrum. Now, several cell phone towers antennas are used to cover a large geographical area. Each tower (base station) covers a circular area called cell. A large geographic region is divided into a number of cells, allowing different base stations use the same channels / frequencies for communication.

Another important aspect of this division in cells, is that cell phones need less power to transmit to reach any base station and covering a smaller area. Reducing the energy required for transmission, battery size and weight is reduced accordingly. This contributes to the reduction in size of cell phones would not be possible without the cellular technology.

When you use your cell phone, your phone locates first base with the strongest signal station and requests a channel. The base station allows access to the channel and the call is then accepted. The call is then sent to the local telephone network if the call is for a common phone, otherwise will be transmitted by the mobile network.

The Cellphone

When the cell phone is connected, the SID (System Identification Code) in the control channel is equivalent to the SID the phone. If the SID is identified, the phone understands that the cell is communicating with the local system. The phone sends a registration request, along with the SID and the MTSO keeps the course of the phone’s location in the database. If the control does not identify the SID of your phone, then your phone is roaming.

Major cell phone manufacturers

Most popular cell phone models on the market are produced by Nokia, Sony Ericsson, Motorola, Samsung, LG and Alcatel, among many others.
