Main components of a computer

The Computer On The Inside

The central processing unit (CPU) and the main memory are chips that can be found clipped to the mother board in the system unit .

The CPU is the processor of the computer , it is the brain where all the system combines together . The CPU measures also the speed of your computer mostly in Mhz or Ghz .

The main memory is the primary storage of the computer . It stores the data and instructions that are held  there for use of the CPU .

The backing storage is where you store amounts of data outside of the main storage .You must have at least one form of backing storage.

What is a bus ?

A set of parallel connecting to two or more units forms what we call a bus . A bus is a data roadway along which data and commands travel .The greater the capacity of the bus is the more speed the computer will have .

In a computer we have three types of buses :
    -The address bus
    -The data bus
    -The control bus .
