INDEX

• A power supply unit (PSU) is a hardware device that converts AC electricity into DC electricity and then distributes it to the rest of the computer.
• The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters.

POWER SUPPLY UNIT

• A CPU, or central processing unit, is a hardware component that is the core computational unit in a server. It handles all types of computing tasks required for the operating system and applications to run.
• A graphics processing unit (GPU) is a similar hardware component but more specialized..

CPU and GPU

• A computer's motherboard is typically the main printed circuit board within a computer.
• It distributes electricity and facilitates communication between and to the central processing unit (CPU), random access memory (RAM), and any other component of the computer's hardware.

Motherboard

Internal connectors

types of connectors

nternal connectors are found inside a computer case. There are two primary types of connectors found internally: socket connectors and power connectors.

What are they?

The external connectors of a computer are designed to receive electrical power from power sources, send or receive data (input/output) to or from other computers or digital equipment, and to interconnect units of the same computer together.

external connectors

RAM stands for Random Access Memory, and ROM stands for Read Only Memory. RAM is memory that stores the data that you're currently working with, but it's volatile, meaning that as soon as it loses power, that data disappears. ROM refers to permanent memory. It's non-volatile, so when it loses power, the data remains.

A hard disk drive (HDD), hard disk, hard drive, or fixed disk, is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material.

hard drives

A computer peripheral, also known as a peripheral device, is an external device that connects to a computer to expand its capabilities. Peripheral devices are not essential to the functioning of a computer, but they enhance its functionality. These devices can be input devices, output devices, or both.
