However, the user was required to prepare a job that included the program, control information, and data on the nature of the job on control cards. The user did not directly interact with the computer system for job execution in a simple batch operating system. There are mainly two types of the batch operating system.

When a job is successfully run, the operating system releases its memory.

These jobs are stored in memory and executed without the need for manual information.

Processing takes place in the order in which they are received, i.e., first come, first serve.

A job is a single unit that consists of a preset sequence of commands, data, and programs.

A computer system with this operating system performs the following batch processing activities: These job groups are treated as a batch and executed simultaneously. The batch operating system grouped jobs that perform similar functions. Once the programmers have left their programs with the operator, they sort the programs with similar needs into batches. Jobs with similar requirements are grouped and executed as a group to speed up processing. Each user prepares their job using an offline device like a punch card and submitting it to the computer operator. Users using batch operating systems do not interact directly with the computer. People used to have a single computer known as a mainframe. What is Batch Operating System?īatch processing was very popular in the 1970s.

In this article, you will learn about the batch operating system, types, working, and its advantages and disadvantages. The batch operating system eliminates the setup time issue. It only executed one job at a time, and data was sent in batches or groups. In the early 1950s, General Motors Research Laboratories (GMRL) introduced the first Single-Stream batch processing systems. The primary problem at the time was a lack of hard disks. Instead, large mainframe computers were used to process data, with punched cards or magnetic tapes serving as input and output. There were no developed operating systems, complex computer architecture, or secondary memory devices in the 1950s and 1960s. These systems are known as batched operating systems, and users have to prepare a job separately to execute it. Users had no direct interface with the system, and job execution was done in a batch system.

In general, tape drivers or card readers were used for input, and tape drives, punch cards, and line printers were used for output. In the beginning, computers were extremely large machines that ran from a console.
