FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -multiprocessing, in computing, a mode of operation in which two or more processors in a computer simultaneously process two or more different portions of the same program (set of instructions).

Detailed explanation-2: -Multiprogramming means that several programs (sequences of z/Architecture® instructions) in different stages of execution are coordinated to run on a single I-stream engine (CPU). Multiprocessing is the coordination of the simultaneous execution of several programs running on multiple I-stream engines (CPUs).

Detailed explanation-3: -A multiprocessor system is defined as “a system with more than one processor", and, more precisely, “a number of central processing units linked together to enable parallel processing to take place". The key objective of a multiprocessor is to boost a system’s execution speed.

Detailed explanation-4: -Multitasking: When a single resource is used to process multiple tasks then it is multitasking. Multithreading: It is an extended form of multitasking. Multiprocessing: When more than one processing unit is used by a single computer then it is called multiprocessing.
