If a system is non-multiprogramming, then at a time, only a single job is executed by the CPU. There are five jobs present in the main memory and the CPU executes these jobs one after one. The below figure shows the multiprogramming system. In multiprogramming, the operating system chooses one of the jobs from the main memory, and execute it. In this, multiple processes can exist in the main memory simultaneously. Multiprogramming means executing multiple programs at the same time with the help of a single processor. So, there is no need of a programmer to run between the three different rooms many times. In batch processing, we make a batch of similar kinds of jobs and then execute it. To solve this problem, the batch processing came into existence. And to finish a job, the user/machine execute among the three rooms. And the reason behind that is, to place a computer we need three rooms, one room is required for the card reader, the second room is needed to execute the program, and the third room is required for result printing. Batch Processingīefore 1960, it was tough to execute a program with the help of the computer. #JAVA REQUIREMENT FOR QUICKBOOKS MAC SERIAL#That’s the reason behind the name of serial processing. In serial processing, the programs are submitted to the computer one-by-one. The user cannot start executing another program if the previous program does not complete its execution. The serial processing is tough for the users because, in serial processing, more time is required.
