The computer hardware of each PC represents the collection of components which can be touched. These are the main components which are located inside the computer case and all of them work together in order to make the computer run properly. The computer software on the other hand, represents the total of computer programs which are to be installed on the computer. The hardware will function properly only if the proper software is installed on the computer. As you can imagine, the software can not be touched, as it is only computer data.



There are different components which form the computer hardware and in what follows I am going to present them to you. It is only suitable to start with the beginning and that should be the motherboard. The motherboard is the component on which all the other components connect. In order to make the connection between all the components, the motherboard uses different integrated circuits. It is important to know that certain components are only compatible with certain motherboards, and in many cases a change of the components might require a change of the motherboard as well.



One of the most important components which connects to the motherboard is the “brain of the computer”, which is the processor. It can also be called the CPU or the central processing unit. This component makes all the proper calculations which assure that the computer works in a proper manner. The processor communicates with all the other components as well and that is done through the chipset. The CPU connects to the chipset which then connects to the motherboard.



Another important component of each computer is the memory. The RAM or Random Access Memory will store all the data which is provided by the processor, motherboard, video card, and so on. This data is lost as soon as the computer is reset. It is advisable to have as much memory on the computer as possible because the more RAM you have the more data it will be able to store and the better the computer will work.

The video card is an important component as well because it creates the output for the computer monitor. Every computer has a video card, whether an integrated one which is included in the motherboard, or an external one which connects to the motherboard. The external ones are able to produce a much better performance than the integrated ones and because of this they are suitable mostly for gaming computers. The hard drive is the component which stores all the computer data, which is somewhat similar to the RAM, the difference being that the data is kept even after the computer is reset.

In this article I am going to talk about the computer storage external hard drives. As it is natural, I am going to start with the beginning. The computer storage refers to various computer devices, components, and recording media which are used in order to retain digital data. The computer storage device is one of the most important components of a computer. The original computer contained only the hard drive or the CPU, or the processor. The external hard drive is a type of computer storage devices such as a hard disk, but which is external meaning that it is connected to the computer by an USB cable in most of the cases.

There are many types of external hard drives, each having various interfaces such as SATA, IDE, FireWire, USB, and so on. There are many things you need to take in consideration before deciding to buy the external hard drive. First of all you should know what type of data you would like to store on it. If you would like to store movies or games then you should opt for buying a larger hard drive which would be able to store large amounts of data. On the other hand if you would like to store only photos or documents, buying a very large external hard drive would be a bad choice.

The brand can be very important just like in the case of other devices and machines. It is not always advisable to buy depending on the brand but sometimes it is worth it. There are many brands which are specialized in this domain, and as you can imagine, the hard drives offered by these brands are better than the ones of an unknown brand. If you like a certain brand, and if you know that their products are great, then you should go with it.

Once you have identified the hard drive that you want to purchase you should look for the best price offer for it. Visit various stores or browse various websites that sell the model that you wish to buy. There is no reason to pay extra money for the same products just because you did not want to waste some time. Always read reviews for the products that you intend to buy. If the reviews are mainly positive then you should not worry when it comes to buying the product. On the other hand, a product which has received mainly negative reviews it will most likely be bad. I would not advise you to buy such a product which has received negative reviews, but it is your choice. These are just some of the facts about the computer storage external hard drives.

Computers are electronic devices which have become essential for the world of technology in which we live. We can nowadays discover in the market alls orts of computers which present all sorts of features and specifications which determine their quality and which are important for us to become familiar with in the idea of becoming able to analyze them and decide upon their usefulness according to the purposes in which we need to use computers.

Many computer users when hearing about computer data storage usually think about aspects related to mass storage, to optical discs and also to all sorts of magnetic storage type of devices such as the hard disk being included within our computers. In the past terms such as storage and memory were usually immediately related to main and secondary memory which computer users were familiar with. Nowadays, other terms related to storage and memory, are also familiar to most of those working with computers. Such terms are for example the ones of internal and external memory. In fact what computer users should know is that there are various other types of computer memory as well. Besides the primary and the secondary type of memory computers also present a tertiary memory and a so-called offline memory. The tertiary type of memory deals with providing a third level of memory or storage as it is also called and it deals in fact with mounting and dismounting alls sorts of removable type of mass storage media into another storage device according to all sorts of system demands that might be established.



Certainly, these are only some of the numerous important aspects related to computer data storage that can be presented as there are also numerous other ones which might be useful to become familiar with as well. Anyway, all of these aspects are important to be considered by those willing to understand the way in which their computer system operates and the way in which they can improve their PCs and the way in which they can work with them and benefit from working with them.

They can be very useful for us these days and we should be willing to analyze some of their features as some of them might also prove to be useful for us to use sooner or later.



We use computers on a daily basis, at home, at work or while traveling to access the Internet, play computer games, watch movies and so much more. Yet, most of the times if not ever, we never give a second thought to just what our computer is made off. You know it contains hardware components but what exactly they are, how are they called or what is their function within our personal computer are usually questions without answers or with vague ones. I'm going to be talking bellow above about the hardware components for a personal computer that are essential to it:

1. The PC Monitor is the device on which you visualize movies, games, and programs like word editors and Internet browsers. Older models featured a Cathode Ray Tube (hence the name CRT) with controls housed in a plastic case. Their diagonal ranged from 13 to 21 inches. Today LCD monitors have flooded the market, providing wide screen image display and smaller weight compared to their older counterparts, the CRT computer monitors. Most monitors feature controls used to adjust contrast and brightness while others have options to move the image left, right, up or down. CRT monitors also have a degauss option which can be used when the image isn't displayed correctly.

When it comes to picture quality we basically speak of resolution and refresh rate. Resolution is measured in pixels and is connected with how well our monitor displays images. Refresh rate refers to how often your image quality gets refresh. The recommended quality is usually 60 Hz, but since there are so many types of monitors it is best to consult the monitor's manual for the right value. Bear in mind that using a different value other the one recommended in your manual can damage your monitor.

2. The motherboard is the board that contains the CPU, the memory, BIOS, CMOS, Video devices, sound devices, storage devices, chipsets, etc. together with the connectors and logic circuits that tie all parts of your PC together. Together with the wiring in your computer it resembles to the network of veins in your body.

3. The CPU (Central Processing Unit) is considered by some to be a computer inside another computer. This isn't to far from the truth since the processor manages the huge number of instructions given to him by the other computer hardware components similar to how the computer manages the instructions you give it by using external input devices like the keyboard and mouse.

4. The "hard drive" is a storage device with one or more metal disks (called platters), arranged on a spindle, one above the other; with a read/write head (often on an arm that can be moved to a specific point on the recording surfaces. This read/write machine can probably be called the first true 'robot'. Hard drive units are sealed hermetically to keep out dust. Even the smallest particle of dust can damage the platters so it's recommended you don't open them. The most recent hard drives can have up to 1.5 Terra Bytes.

5. The video card is an essential part of any computer. It provides your computer to play video files, computer games and other things. Without a video card to convert the binary code from the CPU and transmit in a graphic way to your monitor you wouldn't be able to watch anything. In some cases the video card can be integrated on the motherboard.

6. The sound card is very much like the video card, with the small difference that instead of converting CPU binary code and send it to your monitor it uses a different type of conversion allowing you to hear sounds in your computer speakers.

7. Over the years the CD-ROM drive and the DVD-ROM have proven to be essential to a personal computer. Information transfer had at its heart this hardware component. In recent years, with the development of the Internet, flash drives and portable hard drives, CD and DVD-ROMs have started to register a slow decline from the information transfer market. They will still be around for some years to come since they are the backbone of the music and movies commercialization.

8. As a last entry to the list of computer hardware components I'll add a duo of hardware parts, namely the keyboard and the mouse without which you couldn't control you computer. That is until technologies similar to the touch screen will appear on the market, but this will undoubtedly take some time.
