They were designed for batch processing.

Explanation

In the beginning, around the 1940s, electronic computers were built without Operating systems. These computers could not do basic calculations, read and write data, or run programs. Setbacks such as these led to the development of operating systems.

The first one was introduced in the early to mid-1950, and it relied on the batch processing systems to facilitate submission of data into groups. Rather than processing tasks individually, this system processed tasks in batches. Upon the completion of a job, the batch would head over to the OS’s software. The software would then dump the state of the active task and open the next one. This helped reduce operator intervention and time wastage.
