Some most popular examples of operating system are: Unix Operating System. In a RTOS, Processing time requirement are calculated in tenths of seconds increments of time. Input statistics are accrued and processed in batches, consequently the name batch processing. This application allows you to send the requests to the Kernel using a function library so that the application can give the desired results. These systems run on a server and provide the capability to manage data, users, groups, security, applications, and other networking functions.
