History of Operating Systems: Early Operating Systems
Before the introduction of personal computers, computers were large and expensive. People primarily operated these early computers through punch cards, and the computers had limited processing capabilities.
Batch Processing Systems
The batch processing system, one of the earliest types of operating systems, automated the processing of large volumes of data. In a batch processing system, users would submit jobs to the computer system in the form of punch cards or magnetic tape, and the system would then process these jobs in batch mode. As a result, the computer would execute a series of jobs without requiring any user intervention until all the jobs in the batch were completed.
Examples of early batch processing systems include the UNIVAC, IBM 704, and IBM 709. Users primarily utilized these systems for scientific and military purposes, such as weather forecasting and nuclear weapons research.
Time-Sharing Systems
As computer systems became more advanced and powerful, new operating systems came up to take advantage of these capabilities.
