All hardware input, output or storage devices require the following items to operate:
Most input/output devices reside outside of the computer these devices communicate with components inside through wireless or throw cables attached to the case at a connection called a port.
Keyboard it the primary input device of a computer and mouse
Monitor and printer are the two most popular output devices
Computer contained these devices inside the case:

Most Computers Contain These Devices Inside the case :
A Circuit Board is a board that holds microchip or integrated circuits and the circuitry that connects theses chips
Expansion slots are a narrow slot on the motherboard where ah expansion card can be inserted. They connect to a bus on the motherboard.
Complementary metal-oxide semiconductor is the configuration and setup of a PC.
Two types of cables inside the case:
A device that is not installed directly on the motherboard is called a peripheral device
A Serial port is so named because data is transferred serially one bit at a time
· A parallel port transmits data in parallel and is most often used by a printer
· A 1394 port (fire wire) is used for high sped multimedia devices such as digital camcorders.
· A USB port can be used by many different input/output device such as keyboards digital cameras etc…
A had drive is a sealed
