Explain the concept of job pool in a multiprogramming system.
The job pool consists of all processes residing on the disk awaiting allocation of main memory.
How does multiprogramming contribute to the reliability of computer systems?
Multiprogramming enables the system to continue operation even if one job fails, by always having other jobs available for execution.
Test your knowledge on how operating systems manage jobs in memory and the job pool, including the process of switching between jobs and handling wait times for tasks like I/O operations.
