Define Components of Computer
A pc is an Associate in Nursing electronic machine that consists of Input & Output devices, CPU, Storage devices, and communication devices. These parts of a pc area unit are necessary so as to control a pc with success. the foremost necessary part of the pc is that the C.P.U. known as conjointly the “Brain of Computer”.
List of main components of a computer system:
- System Unit (Case)
- Central method Unit ( central process unit )
- Motherboard
- Computer memory
- Input devices
- Output devices
- Storage devices
- Peripheral devices
- Communication devices
Categories of Components Of Computer
There are two categories of computer
- External Components
- Internal Components
External Components Of Computer
External parts area unit those parts that area unit hooked up to a pc through a cable to feature additional practicality. samples of external parts area unit the keyboard, Mouse, Printer, etc.
Internal Components Of Computer
External elements are those elements that are connected internally to a laptop. These elements are mounted on the motherboard within the system unit. samples of external elements ar the RAM, CPU, Hard Disk, etc.
Parts Of Computer And Their Functions
System Unit (Case)
The system unit could be a box that contains totally different electronic parts of an ADPS. it's additionally known as the chassis. It protects the interior parts from harm. The electronic circuits within the system unit area unit are connected to a motherboard.

Central Processing Unit (CPU)
The central processing unit is additionally known as a processor. it's conjointly the brain of the pc. It evaluates and executes the commands on the pc. central {processing unit|CPU|C.P.U.|central processor|processor|mainframe|electronic equipment|hardware|computer hardware} is additionally known as the processing unit of a laptop. once anybody buys a laptop, the primary factor to appear out for is that the central processing unit.
It is tough to make a decision between AMD and Intel, dual-core or quad-core, i3, and i7 thanks to the lack of data and their variations. The central process unit (CPU) is additionally known as the pc brain. There area unit different types of computers, laptops, smartphones, tablets, and TVs that have their own central processing unit. this is often a terribly little chip that is tiny in form of an sq. and is mounted on the motherboard of the device.
