There are basically 3 types of memory. They are :
1. Primary Memory - Primary Memory operates at electronic speeds. CPU can directly access the program stored in the primary memory.It consists of a large number of semiconductor storage cells. Each cell is capable of storing one bit of information.Ex- RAM
2.Secondary Memory - This memory type is much larger in capacity and also much slower than the main memory. Secondary memory stores system programs, large data files and the information which is not regularly used by the CPU. Examples for secondary memory devices are magnetic hard disks and CD-ROMs.
3.Cache Memory - The performance of a computer system will be severely affected if the speed disparity between the processor and the main memory is significant. The system performane can be improved by placing a small, fast acting buffer memory between the processor and the main memory. This buffer memory is called as cache memory.
