what is batch operating system with example

Introduction: 

Hello friends welcome to the programming friends website here you can view various programming related articles 

And the topic is what is batch operating system with example.

So let's get started.

Batch Operating System: 

Batch operating system or Batch processing system  was developed when the punch cards was used  to record the users job and this job is done by human.

For Human it was vary tough task to record users job , so to avoid human operator work in this field  the Batch Operating System was invented.

How the batch Operating System Work: 

In this operating system the special batch is stand for sequence of users job and the sequence of user job is decided by the operator 

Next the jobs are recognised with the special markers which indiacting starting  and ending of jobs.

After that  In system the jobs are submitted to the batch processing system  which we called as (BPS)  And then BPS is executed these jobs without any operator interruption.

After execution of job they are send to that particular user who owns it.

 

The main component in batch operating system is Batch Monitor which is permanently placed in part of the memory, and the another part of memory is used by the current job in the batch.

There are three functions of Bach operating system that is :

1. Scheduling.

2. Memory Management.

3. Sharing and Protections.

The above starting two functions are before program execution,and last done after job is executed.

Advantages of batch Operating System:

1. Jobs in are executed in order.

2. Execution is systematic.

Disadvantages of Batch Operating System:

1. This is very time consuming .

2.It is very difficult to set job priorities.
