Write short notes on time-sharing? |
|
Answer» This is a one of the features of Operating Systems. It allows execution of multiple tasks or processes concurrently. For each task a fixed time is allocated. This division of time is called Time- sharing. The processor switches rapidly between various processes after a time is elapsed or the process is completed. For example assume that there are three processes called PI, P2, P3 and time allocated for each process 30, 40, 50 minutes respectively. If the process PI completes within 20 minutes then processor takes the next process P2 for the execution. If the process P2 could not complete within 40 minutes, then the current process P2 will be paused and switch over to the next process P3. |
