Batch Operating System : In the early days this system was used. Those days, the jobs were placed in a job queue and the memory allocate managed the primary memory space, when space was available in the main memory, a job was selected from the job queue and it was loaded into memory. Once the job loaded into primary memory, it competes for the processor. When the processor became available, the processor scheduler selects job that was loaded in the memory and execute it. In batch processing is implemented to provide a batch file processing. So in this approach files of the similar batch are processed to speed up the task. It resulted in improved system utilization and performance of machine, due to reduced turnaround time of execution job. In batch processing system, earlier the jobs were scheduled in the order of their arrival that first comes first out(FIFO) / FCFS. This scheduling method was easy and simple to i...
