Types of computers in general





Computers in general are different ability to process data, the mismatch with a limited capacity for treatment, including a high-capacity, to suit different needs and costs, and here is a look at the main types:



× computers or large central or so-called Mainframe: such as computers used in banks and government institutions such as the Ministry of the Interior. Etc. can not the average person charged with the purchase price of one because they cost millions of dollars or hundreds of thousands at least, has the ability to handle huge amount of data such as information of millions of citizens.

× personal computers Personal computers: the systems used by ordinary users at home or work and the price of these devices hundreds or thousands of dollars, and is used for word processing or surfing the Internet, games, entertainment and education and is divided into two main sections:

v office systems Desktop: This equipment is greater than the second type are suitable to be placed on an office in the home, at work and the price per unit, less than a second type, we can not make this kind where the size of a large caravan.

v notebooks Notebook which Calculators small (a few inches in length and width and a few centimeters in height) and are usually used for use during travel such as travel, which is a "PC portable" because of the light weight and being a one-piece, and works of this type battery rechargeable to be used During the movement, this computer is running the same programs and performs the same functions of the computer desktop, but with maintaining weight and low volume, so it is more expensive than the first.



× Servers Servers: are computers used in computer networks to be the main center of the network where the data storage and network management, must be the computers powerful enough to be able to accommodate the number of computers remained strong, and in fact with the development of the power of personal computers are being used Khacbat maid appeared in Currently the difference between PCs and servers is shrinking gradually.



In the past we divide the computers into three sections: a central and a mini and personal. But with the stunning development that hit personal computers became possible to build a convergence of personal computers mini-computers in the Force.



Original Brand name and the compound Compatible





When we talk about IBM-and computers are compatible with you should know the important thing: that the computer device customizable, meaning it when you bought it thinking I am unable to choose the technical specifications that I like the example I can buy a computer to surf the Internet but it lacks the capabilities of voice, or a computer has the components in full, The important thing I can choose PC components to fit my needs and Mizzati, so the computer does not come from the factory in one piece, but combines this computer from a range of different pieces from different companies and different countries.



Experienced users can collect spare computer with each other to form a full computer without special tools (I do so at home I do not need more than a screwdriver) is not the problem.



For example, a company put the sound card (a piece installed in the computer may enable him to issue the vote) and put another sound card again with different specifications. And so on, to find in the market, dozens of species, so you can you the user to choose from these types of appropriate you need and money Vtstraeh and install it on your own, and so choose the other pieces in your computer until you have a computer completely, of course, no secret to you that these pieces vary greatly in themselves in the quality and speed of performance of work required of them, so the person who wants to buy a computer to choose the components that will enter in the composition calculator.

And of course the hardware has the inherent level of quality higher than the combined devices, as well as the level of after sales services because companies that sell a keen desire to reputation
