With the aid of an example, describe the following data processing modes.
a) Batch processing
b) Timesharing processing
c) Distributed processing


Answer:

a) Batch processing-it is a mode where jobs are accumulated over a period of time and then processed at a pre-set time. Data collection is usually done offline that is in isolation of the CPU. It is used in payroll processing.
b) Timesharing processing-it is a processor mode where the central processor serves two or more users with different tasks. Each task is allocated a time slice of the processor time. Control is switched from one job to another. It is suitable for learning institutions where there are several users.
c) Distributed processing-it is a mode where the task being processed is divided among computers. These computers are in different geographical areas but linked with a transmission medium. It is used in the banks and library systems.
