Answer 2

Answer:

A==>3

B==>1

C==>2

D==>4

Explanation:

Process: A process is a program in execution that then forms the basis of all computation. The process is not as same as program code but a lot more than it. A process is an 'active' entity as opposed to the program which is considered to be a 'passive' entity.

Program: A process is an 'active' entity as opposed to the program which is considered to be a 'passive' entity. A program is a piece of code that may be a single line or millions of lines.

Long term scheduler: Long Term scheduler mainly controls the degree of Multiprogramming. The purpose of the long-term scheduler is to choose a perfect mix of IO-bound and CPU-bound processes among the jobs present in the pool.

Message passing: Message Passing provides a mechanism to allow processes to communicate and to synchronize their actions without sharing the same address space.
