There are a huge number of incorrect terms that beginners are trying to call the computer system unit - this is the processor, case, 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 clarification, they continue to be used by man. Indeed, psychology is a subtle science. We hope that this article will once again remind you that the use of the correct terms not only means respect for the interlocutor, but also allows you to choose a good computer system unit when purchasing or self-assembly.
Definition
If we turn to the encyclopedia, we can read the following: the computer system unit is a case in which all the main components of the computing system, including the power source, are located. It can be made of metal (steel, aluminum), polymers, as well as wood and even glass. In other words, the case alone cannot be called the “computer system unit”, just like the components assembled “on the knees” are not. Just like wheels without a cab, you can't call a car.
How to build a computer yourself
Buying a computer system is a whole event, because the future convenience of working with programs depends on the correct selection of components. For example, a person who wants to transcode video and audio streams, but who buys a budget central processor, will be forced to spend hours waiting for the operation to complete.
The reverse is also true: if the main tasks that are solved on a computer are typing and printing them, powerful components are not only useless, but also undesirable, since their purchase entails excessive financial costs, as well as more tangible
bills on 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 basic components that make up a computer. These include:
- Motherboard. It is one of the main parts, since all the other components are connected to its connectors. It is its characteristics that determine which components can be used in the assembled computing system.
- The central processor. This large microcircuit performs all mathematical calculations. Therefore, the performance of the whole system as a whole depends on the performance of this element. The entire assortment can be conditionally divided into three groups: budget ones, characterized by low cost, relatively low speed, sufficient for office tasks and a low level of energy consumption; universal; top ones that use the principle of "performance at all costs."
- RAM. Without this module, system operation is not possible. Modern solutions use DDR3 boards. When choosing, you can use the principle "the larger the volume, the better."
- Storage device. Most often, they have a hard drive, although now they are being abandoned in favor of SSD solutions.
- Video card. Displays the image on the screen. It can be represented as a separate device, as well as integrated in the processor or chipset.
- Power supply unit.
