Compare batch processing systems and multiprogramming …

The main difference between batch processing and multiprogramming is that batch processing allows multiple programs to execute with minimum human interactions while multiprogramming allows multiple programs to execute on a single processor system. Multi-Programmed Batch System: In multiprogramming, multiple programs (or jobs) of different users can be executed simultaneously (i.e. at the same time). The multiple jobs that have to be run simultaneously must be kept in main memory and the operating system must manage them properly. Batch systems can work offline so it makes less stress on processor. Processor consumes good time while processing that mean it knows which job to process next. In real time systems we don't have expectation time of how long the job is and what is estimated time to complete it.
