Time sharing: Time sharing operating system was developed when computer systems were very expensive and shared by multiuser at the same time. This operating system enables the multi-users to share the particular system resources at the same time. In this technique, each and every task of the user is given specific time and the system restricts the execution of each task or job to only one interval at a time which assist the system to perform all the tasks smoothly without being interrupted. This operating system uses CPU scheduling and multiprogramming technology to offer each user small portion of time to perform their operation. Multitasking : As the name implies the term multitasking means several task is being processed at the same time. This technique contains common processing resources like a CPU and this resource is shared by each task or process. Practically, it is very difficult for a computer with single CPU to process more than one task at the same time this is when multitasking operating system becomes handy. It uses scheduling techniques that decide which task should be a running task and when the other tasks in queue should be performed. This operating system performs these operations with the help of a signal or interrupter which indicates CPU to keep the current task aside and save the present status in the buffer and return to another task.

Chapter 3.1, Problem 4QE

Program Plan Intro

Time sharing:

Time sharing operating system was developed when computer systems were very expensive and shared by multiuser at the same time.

This operating system enables the multi-users to share the particular system resources at the same time.

In this technique, each and every task of the user is given specific time and the system restricts the execution of each task or job to only one interval at a time which assist the system to perform all the tasks smoothly without being interrupted.

This operating system uses CPU scheduling and multiprogramming technology to offer each user small portion of time to perform their operation.

Multitasking:

As the name implies the term multitasking means several task is being processed at the same time. This technique contains common processing resources like a CPU and this resource is shared by each task or process. Practically, it is very difficult for a computer with single CPU to process more than one task at the same time this is when multitasking operating system becomes handy.

It uses scheduling techniques that decide which task should be a running task and when the other tasks in queue should be performed.

This operating system performs these operations with the help of a signal or interrupter which indicates CPU to keep the current task aside and save the present status in the buffer and return to another task.
