Batch Operating System:In early computer systems, the user did not interact directly with the computer system. The data and programs were first prepared on the input media such as punched cards or punched tape. The data and programs prepared on the punched tape or punched cards were referred to as jobs. These jobs were submitted to the computer operator. The computer operator would arrange the jobs into proper sequence known as batches and run the batches through the computer. The batch operating system was used to manage and control such type of operations. The simple batch operating system transfers the jobs to the processor one by one.
