Computer Central Processing Unit (CPU)

Today we are considering the central processing unit of the computer CPU (Central Processing Unit – Central Processing Unit or CPU). This is the heart of the system unit or, if you like, its brain! In computer jargon it is sometimes called “stone” (crystalline silicon really looks like a stone).

This is the main processor of information coming into the computer. The central processor performs all the necessary mathematical operations with the incoming data, makes various samples from the databases, archives and unzips our files, deals with video encoding, processes the model of the physical interaction of particles in your favorite computer game, finally!

Computer system unit, device and composition

So, what does the computer system unit consist of? An important clarification here is that under the word “computer” different people can mean, oddly enough, different things: a monitor, a printer, a computer case, even … a computer mouse! But what about? Indeed, “the arrow on the monitor does not move” means that the computer is not working! 🙂 But you and I will be interested in exactly that “iron box that stands under the table”, and the name is its system unit! 🙂

Note: the system unit, as a rule, is called a computer already assembled and ready for operation, and the case is just an iron box into which its various components can be installed.

For greater clarity (to consider all the components of the computer separately), you can read the article on assembling a computer with your own hands. Continue reading

Liquid and air cooling of the computer

Now almost every house has a computer. These electronic machines consume kilowatts from our outlets. Of these, only a small part is spent directly on calculations, and the rest is processed into heat.

The hottest component of a PC is the processor. It is so hot that it burns itself without cooling in about 10 seconds. Modern processors are becoming more and more “cold”, however, they are still far from the heat emission of household devices, such as, for example, a DVD player.
