CPU's

1)The purpose of the Cpu is to control the movement of data and instructions and to fetch data and instructions from memory.

2)GHz stands for gigahertz, which means 1 billion cycles a second. So 2.2 GHz mean 2.2 billion cycles a second.

3)a duel-core processor means there are 2 CPUs.

4)   A CPU cache is a cache used by the central processing unit of a computer to reduce the average time to access memory. The cache is a smaller, faster memory which stores copies of the data from frequently used main memory locations.

5) things that affect the cpu.Frequency of the cpu, number of cores, speed of memory bus, word width, information architecture, size of local cache.
