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 .
