CPU Bound Program

Q1. Explain CPU Bound.

Ans. CPU bound programs use their quantum without performing any blocking I/O operation. One could make better use of the computer’s resources by giving higher priority to I/O bound program and allow them to execute ahead of the CPU bound programs.

Process Management

Q1. What is Process Management?

Ans. A batch system executes jobs, whereas a time-shared system has user programs, or tasks. Even on a single-user system such as Microsoft Windows, a user may be able to run several programs at one time: a word processor, a web browser, and e-mail package. Even if the user can execute only one program at a time the operating system may need to support its own internal programs activities, such as memory management. In many respects, all these activities are similar, so we call all of them processes.
