We can regard it as being the brain of the system.
The CPU has the following functions:
1. Takes the instructions and data from the input device unit(s);
2. Keeps the instructions and data into memory unit;
3. Takes instructions and data from memory unit as and when are required to be for processed;
4. Executes the instructions one by one and sends corresponding signals to relevant unit, after it interprets them;
5. Performs all necessary arithmetical and logical operations in ALU;
6. Controls and dispatches the activities of all other implied units;...
