Main Components of a computer




The Central Processing Unit (CPU) and the Main Memory (RAM and ROM) are found in the system unit.

The CPU is the brain of the computer, it governs the overall speed of your computer.


The Main Memory is a part of a computer system where data instructions are held for use by the CPU and where the CPU puts results it generates.


There are three types of buses that are always going from the CPU to the Main Memory(RAM and ROM) These are :

1. Address Bus
2. Data Bus
3. Control Bus

 A bus is a set of parallel wires connecting two or more components of a computer.
