Purposes of basic computer components
A lot of components contribute for a computer to work. Below are some purposes of basic computer components.
Motherboard is the main circuit board of a computer. It works as a connector for attaching other additional boards. It contains all the important controllers such as CPU, memory, processor socket, BIOS, parallel ports, expansion slots, display screen, disk drive, keyboard etc.
Power supply basically supplies electrical energy to the different parts of the computer components in order to operate the parts of the computer. The computer cannot function without the electrical power supply.
A hard disk is a magnetic disk that store large amount of computer data and provides access to them. It can store from 10 to more than 100 gigabytes.
Random access memory (RAM) provides spaces for the computer to store data for processing by a computer's central processing unit (CPU). The data is only stored in the Ram as long as the computer is operating. The data disappears when the computer is turned off. The data is only stored temporarily so, the data can be erased or re-written.
Floppy disks are small, removable, media storage devices. They record data onto a thin, circular magnetic film encased in a flat, square plastic jacket. Floppy disks are somewhat antiquated, having been replaced by memory sticks and re-writable CD storage devices.
