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:

  3. Memory
  4. Hard Drive
  5. Cd Rom

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
