Components of a computer

Each PC user knows that the computer consists of a monitor, a keyboard, a mouse, speakers and a system unit. But, if we look inside the system unit, we will see a large number of details, because of which it works.

The most important component, of course, is System unit.

In fact, the system unit and is the computer, which performs hundreds of thousands of operations. If we replace the instructor, the keyboard or the mouse, we will just watch films, listen to music, text key, etc., but the PC parameters will remain the same. Everything that is displayed on the instructor or which is heard in the speakers depends on what is inside the system unit. The internal components of the system unit are determined by the capacity of the whole system.

The computer system unit contains: video card, hard drive, RAM modules, coolers, processor, motherboard, as well as other components. Let’s analyze the most important components.

Motherboard – is the basis of the system unit.

This is a plate, on which all the other components are mounted: video card, processor, hard drive, etc. Because of this name and name. The main function of the motherboard is linked to other components, so that they operate as a whole.

Processor – It’s a kind of computer brain.

Even the processor performs all commands, which establishes the user of the PC. The speed and capacity of the computer depends on the processor force. The processor is located on the motherboard in a special connector, called «CPU location» or «socket».

Cooler. This component is above the processor.

The cooler represents a small radiator with a fan, which dissipates the heat and thus cools the processor. It is a very important component, because if the processor is overheated, the calculator will close. And this will quickly lead to a PC defect.

Hard drive – It is a component that stores all the information on the PC.

Of course, the larger the volume of the hard drive, the more information the computer can store. In modern calcium, the DSIK hard location differs from the ancients. Hard discs are now connected via the interface. As a rule, hard drives are also overheated for a longer computer life, uphill a cooling near the hard drive, and therefore you will avoid repairs.

Graphics card – Part of the computer, responsible for the video processing speed.

In modern shifts, the graphics card is mounted on the slit PCI-Express. The strong graphics card is necessary for those who work with graphic elements or lovers of computer games – for a clearer image or better feel the atmosphere of the game. In addition, each computer has a network and a sound plate. Their name talks about its function in the computer.

Module – In other words, memory with random access (it is the translation of the random access memory of English expression, abbreviated RAM).

In RAM memory, the data is temporarily stored, which is necessary for the processor, to carry out the operation. After completing these processes, for example after completing an operation, RAM data is deleted. The speed of the RAM, or more precisely access, is higher compared to the speed of access to the hard drive. This provides instant access to the necessary information. There are different RAM models, so slots on the motherboard are also different.

These are not all the details that make up the computer. To extend the capacity of the PC is mounted TV, modems, etc. It all depends on the wishes of the user.

And, of course, to work on everything you need an electrical supply, which will give life to everything you have set up on the computer.
