3) What’s the difference bet. batch system ,multiprogrammed systems, and time-sharing systems?

• The difference bet. batch system ,multiprogrammed systems, and time-sharing systems is that batch system is one in which jobs are bundled together with the instructions necessary to allow them to be processed without intervention. Often jobs of a similar nature can be bundled together to further increase economy, then the multiprogrammed systems is a method by which multiple tasks, also known to processes , share common processing resources such as CPU. In the case of a computer with a single CPU, only one task is said to be running at any point in time, meaning that the CPU is actively executing instructions for that task while time-sharing is were you have a primary computer or shall we say the sever and there you would connect the other computers and the server will serve as the main PC.
