Which is the difference between Multiprocessing,, Multitasking and Multi threading

Multiprogramming – A computer running more than one program at a time (like running Excel and Firefox simultaneously).Multiprocessing – A computer using more than one CPU at a time. Multitasking – Tasks sharing a common resource (like 1 CPU).

What is a CPU?

A central processing unit, also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output operations specified by the instructions in the program.
