Q. Explain about Batch System?

  • A number of computer systems only did one thing at a time. They had a list of computer system can be dedicated to a single program till its completion or they can be dynamically reassigned among a collection of active programs in various stages of execution.
  • Batch operating system is one where data and programs are collected together in a batch before processing starts. A job is predefined sequence of commands, data and programs which are combined in to a single unit known as job.
  • Fig. belowportrays memory layout for a simple batch system. Memory management in batch system is very simple. Memory is generally divided in two areas: User program area andOperating system.

  • Scheduling is simple also in batch systems. Jobs are processed in the order of submission which means first come first served fashion.
  • When a job finishes execution, its memory is released and output for the job gets copied in an output spool for later printing.
  • Batch system generally provides simple forms of file management. Access to file is serial. Batch systems don't need any time critical device management.
  • Batch systems are inconvenient for users since users can't interact with their jobs to fix problems. There can also be long turnaround times.
