Why was batch processing the norm before time sharing became popular
Why was batch processing the norm before time sharing became popular?
In the 1970s, batch processing was quite common. The tasks were carried out in groups. In the past, each person had a mainframe, which was a single computer. Users using batch operating systems don't speak to the machine directly. Each user creates their own work and submits it to the computer operator using an offline tool like a punch card. To expedite processing, jobs with related needs are combined and carried out together. The programmers group programmes with comparable requirements into batches after handing the operator their codes.
Jobs that carry out similar tasks are grouped together by the batch operating system. These work groupings are handled as a batch and carried out concurrently. These batch processing tasks are carried out by a machine running this operating system:
A job is a single entity made up of a predetermined order of orders, information, and programmes.
Processing happens first come, first served, meaning that it happens in the order that they are received.
These tasks are carried out without the need for manual input since they are retained in memory.
The operating system frees up memory when a job has been completed successfully.
