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)

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.

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.


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!

The computer functions

A computer is basically a device whose primary function is to process large amounts of data with great speed and accuracy, task is accomplished by hardware components, ie the physical part, and software, which are programs. A PC can perform many complex tasks, and for that uses a set of instructions, the aforementioned software, that basically are orders that the computer must process through the hardware, producing an output data an understandable format for its users.

As mentioned, a computer is composed of two subsystems, hardware and software, where the first of which comprises the computer itself and all peripherals input and output, including keyboard, mouse, monitor, printer and other, while the software subsystem includes the operating system, which is responsible for translating what we do to PC language, and all user programs, i.e. office suites, design software, modeling, mathematical software, and many others.

Computer functions

What does “process information”?

The action of “process” is related to the act to modify or transform something from its original state to a new one. The computer can process information from different types: text, numbers, images, sounds, and many others sources. The information you work the computer must be entered by the user.

The computer ability for data process can be summarized through the following basics:

Store information:

The computer has the ability to store, in a small space, large amount of information that otherwise would have to print in thousands of paper sheets.

Computer functions

Organize information:

This feature gives the user the option to sort or organize the information according to their own needs and requirements. By this way, we can find and examine documents and data the number of times we want.

Retrieve Information:

His great ability to store information would be useless if we cannot quickly and easily retrieve and examine it. In this regard, the computer offers us the possibility to check instantly and accurately any information you have previously saved on it.

Computer functions

Transmitting information:

One of the most important features of the computer is the ability to share information between users quickly, securely and accurately. This fantastic feature depends on whether our computer is connected to the Internet or local network.

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.
