MULTIPROGRAMMING -:
It is the process of loading more than one program into the
memory so that processor can be kept busy by switching
between any of the loaded programs.
Example -:
let us say there are 2 programs waiting in the pool to be
executed by the CPU,so the OS picks the first program and
executes. if the program has some I/O operations
involved,then it puts this program in the queue and picks
the second program and executes,meanwhile the first program
receiving its input.

MULTITASKING -:
It is the ability of a computer to handle a number of jobs
or tasks simultaneously.It is basically for single user
with multiple programs.
Example -:
let us say we are printing a document of 100 pages while
computer is performing that,we can still do other jobs like
typing a new document,so more than one task is performed.
