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!

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
Do-it-yourself installation of RAM should be done in a case in which there is already a fixed motherboard and processor. Something like this:
Do-it-yourself RAM installation
In the photo above we see that the installation of RAM has already been done. We also see the installed motherboard and power supply (indicated by an arrow).
In general, it must be said that if you buy a computer case, then often it comes with a power supply unit and you do not need to install it. But in any case, the procedure for installing the power supply in the case is not difficult: put it in the space provided for this (usually at the top of the system unit) Continue reading
