what is a cpu?
CPU stands for Central Processing Unit. There can be several processors in a computer, but one of them is the central one – the CPU.The reason the CPU is called a processor is because it can work with data. And it has two important jobs:
1. It can do calculations. 2. It can move data.
The CPU is very fast at doing both jobs. The faster the CPU can do calculations and move data, the faster we say the PC is. There are three ways to improve a PC’s performance:
1. Higher clock frequencies 2. Greater bus width.
3. Optimising the core of the processor and other components so that the maximum amount of work is
