What does the computer system unit consist of?

There are a lot of wrong terms that beginners try to call a computer system unit - a processor, a case, an iron box located under the desktop. It's hard to say where these erroneous names come from, but they are incredibly tenacious. And sometimes, even after an explanation, continue to be used by a person. Indeed, psychology is a subtle science. We hope that this article will again remind that using the right terms not only means respect for the interlocutor, but also allows you to choose a good computer system unit when buying or assembling yourself.

Definition

If you refer to the encyclopedia, then you can read the following: the computer's system unit is a case in which all the main components of the computer system are located, including the power supply. It can be made of metal (steel, aluminum), polymers, as well as wood and even glass. In other words, a single case can not be called a "computer system unit", as well as components assembled "on the knees," nor are they. Just like the wheels without a cab can not be called a car.

How to assemble the computer yourself

The purchase of a computer system is a whole event, because the future convenience of working with programs depends on the correct choice of components. For example, a person who wants to transcode video and audio streams, but at the same time buying a budget CPU, will have to spend hours waiting for the completion of the operation. The converse is also true: if the main tasks solved on the computer are typing and printing them, then powerful components are not only unnecessary, but also undesirable, since their acquisition is associated with excessive financial costs, as well as more tangible accounts for Payment of electricity. Thus, before you buy a computer system unit, you need to determine the range of tasks that will be solved on it most of the time.

Components

We have already mentioned the main components of which the computer consists. These include:

- Motherboard. It is one of the main parts, since it is to its connectors that all other components are connected. It is its characteristics that determine which components can be used in the collected computer system.

- The central processor. This large microcircuit performs all mathematical calculations. Therefore, the performance of the entire system depends to a great extent on the performance of this element. The whole assortment can be conditionally divided into three groups: budgetary ones, characterized by low cost, relatively low operating speed, sufficient for office tasks and a small level of energy consumption; Universal; Top, which uses the principle of "performance at any cost."

- RAM. Without this module, the system can not be operated. In modern solutions, DDR3 boards are used. When choosing, you can use the principle "the larger the volume, the better".

- Storage device. Most often they are the hard drive, although now they are abandoning them in favor of SSD-solutions.

- Video card. Displays the image on the screen. Can be presented as a separate device, and also built into the processor or chipset.

- Power supply unit.
