Concentrate on one task:- In modern operating system there are running multiple tasks at a time. Multitasking In a nutshell, both the terms are often used in conjunction with each other to represent modern operating systems, but with different objectives and functionality. It is easy to confuse multitasking with , a somewhat different idea.

As an example, let's look at the printer. On the other hand, a multi-user operating system allows more than one user to access a computer system at one time.
Windows prior to Windows 98 operating system used to be single user single task type.

Difference between Multiprogramming and Multitasking Terminology of Multiprogramming and Multitasking The term multiprogramming is a rudimentary form of parallel processing meaning multiple processes run concurrently at the same time on a single processor. Generally, a network is laid down, so that a computer can be remotely used. As you might know that many devices within the systems generate intterupts and when an inturrpt occurs the processor suspends the execution of currently executing task , saves its state and executes some another Interrupt Handler e. The idea is to effectively utilize the processor to create multiple ready-to-run processes with each process belongs to different user.
