Question

A currently running process can be put on a ready queue or one of the I/O queues by each of the following except _______ .

• A. The process issued an I/O request
• B. The process did an illegal memory access
• C. There was an interrupt
• D. The process issued a system call

Hint:

Illegal memory accesses result in exceptions, which interrupt normal process scheduling. Make sure to handle memory violations properly in your code.

Answer 1

The Correct Option is B

If a process performs an illegal memory access, it will typically cause an exception or segmentation fault, and it will not be moved to the ready or I/O queues. In contrast, a process that requests I/O or issues a system call can be scheduled to wait on I/O or for the system call to complete.
