Module

Module is to connect the channel of CPU and other equipment, rise to buffer and data exchange action. When the CPU at work, it needs read dates from hard disk and external memory read data etc. but due to the too big" warehouse" of hard disk , plus it is "far" from CPU ,so the speed of transportation "raw" data is slow, lead to the CPU production efficiency is much worse! In order to solve this problem, the people then built a small "warehouse" between CPU and external memory ,it is memory.
