Motherboard
Motherboard - a printed circuit board, which is the basis for building a modular device, for example, a computer. The motherboard contains the main body of the device, the processor, RAM, and additional interchangeable cards called expansion cards.

Power Supply Unit
Power Supply Unit - a device designed to convert AC voltage from the mains into DC voltage for the purpose of powering a computer or server computer. To some extent, the power supply also performs the functions of stabilization and protection against minor disturbances in the supply voltage.

CPU
Central processing unit - an electronic unit or an integrated circuit that executes machine instructions (program code), the main piece of hardware in a computer or programmable logic controller. Sometimes referred to as a microprocessor or simply a processor. The main characteristics of a CPU are: clock speed, performance, power consumption, norms of the lithographic process used in manufacturing (for microprocessors), and architecture.

GRAPHICS CARD
GPU - a device that converts a graphic image stored as the contents of computer memory into a form suitable for display on a monitor screen. Video cards are not limited to simple image display, they have a built-in graphics processor that can perform additional processing, removing this task from the computer's central processor.

Network Card
Network Card - an optional device that allows the computer to communicate with other devices on the network. By constructive implementation, network cards are divided into: internal, external, built into the motherboard.

SOUND CARD
SOUND CARD - additional equipment of a personal computer and laptop that allows you to process sound (output to acoustic systems and / or record). At the time of their appearance, sound cards were separate expansion cards installed in the corresponding slot. In modern motherboards, they are presented as a hardware codec integrated into the motherboard

HDD
HDD - random access memory device (information storage device, drive) based on the principle of magnetic recording. It is the main storage of data in most computers. Unlike a floppy disk, a storage medium is usually combined with a storage device, a drive, and an electronics unit. Such hard drives are often used as non-removable storage media.

RAM
Random Access Memory - in most cases, a volatile part of a computer memory system, in which executable machine code (programs) is stored during computer operation, as well as input, output and intermediate data processed by the data processed by the processor. The data contained in the semiconductor random access memory is only accessible and retained when the memory modules are energized. Turning off the power of the RAM, even for a short time, leads to the loss of stored information
