Information about 3 parts of CPU :
MU → Memory unit :
This is the important unit this is the part which keeps/stores information for short period of time or also it could be changed according to our need, even we can change for being permanently.
ALU → Arithmetic and Logical unit :
This is also a unit this shows the arithmetic calculations and logical operations ,step by step calculating process is done here ,perfectly within seconds.
CU → Control unit :
This is one of the unit which perform as a cleaning manager "traffic police" cleaning unwanted files and also manages all the operations of a computer.
