Curiosity is inherent not only to children, but also to adults. Without a doubt, every owner of a personal computer system has repeatedly tried to look inside the system unit to see the computer device.
For some, this is the secret “behind seven seals”, and for others (for example, service center employees) it’s an opportunity to make money out of ignorance of the former. So, understanding the computer’s device, you can independently clean the cooling systems and some other components from dust, while not doubting the quality of the work done and not worrying about the safety of personal data.What is inside a noisy metal box called a system unit? We list the main computer devices and their functions.

- Main (motherboard) board. It is the basis for combining all components into a single system. It contains connectors for connecting components, internal buses, voltage converters , etc. A very important element without which a computer device cannot be considered. Although budget models can cope with the main tasks quite successfully, all manufacturers offer more advanced solutions that are distinguished by an enhanced power supply circuit, additional cooling, etc.- . , . , . , , (DDR2, 3 .).
- The central processor. Physically represented by a fairly large microcircuit, which includes many transistors. Performs all mathematical calculations. Considering the internal devices of the computer in the assembled system unit , you will not be able to see the processor, since it is closed by a cooling system - a fan (cooler) and a heat sink radiating heat. The most important parameter is the clock frequency, which indirectly indicates performance. There are single-core (almost discontinued) and multi-core models.Considering the computer device, it should be noted that the four above components are necessary for the functioning of the computer. So, if you can turn on the system unit without a monitor, then it is impossible to work without a processor.
