A video card is that device with which the image is displayed on the monitor. Those. without a video card, we won’t see any text or images on the screen, and in general, computer operation without a video card is impossible.
There are two types of video cards: external video cards (discrete) and built-in (onboard from English “On board” – on the board). Let’s look at these concepts together in more detail. There are two monopolists on the external video card market now. These are California-based Nvidia and Canadian ATI Technologies. In 2006, the latter was also purchased by the American processor company AMD (Advanced MIcro Devices). Continue reading
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!

In this article we will talk about one of the most important parts of a computer – the power supply, you will find out what important role it plays in a personal computer. The main function of the power supply unit is to convert the AC voltage in the household power supply network (220 V) to DC, with a nominal value of 12 (twelve), 5 (five) and 3.3 (three) Volts, which various components of our computer consume.
The computer’s power supply is responsible for the uninterrupted power supply of the entire system unit. The failure of this node completely de-energizes the computer and it stops turning on. Or it starts to “glitch” in the most unpredictable way, which is also not kosher 🙂 Continue reading
