Short term scheduler is

• dispatcher

• select task from secondary storage

• put task in waiting queue

• select task from new process created by fork

What is the primary function of a long-term scheduler?

• To allocate CPU time to processes

• To handle I/O operations

• To manage memory allocation

• To select processes from the job pool

Which of the following best describes a medium-term scheduler?

• It manages the execution of I/O requests

• It executes processes in the ready queue

• It prioritizes tasks based on urgency

• It swaps processes in and out of memory

What is the role of a dispatcher in process scheduling?

• To terminate processes that are no longer needed

• To switch the CPU from one process to another

• To load processes into memory

• To monitor process execution time

What is the significance of the ready queue in process scheduling?

• It stores processes that are ready to be executed by the CPU

• It contains processes that are waiting for I/O operations

• It holds processes that are currently executing

• It manages processes that have been terminated

Turn variable in Peterson algorithm of CS will satisfy the requirement of

• mutual exclusion

• bounded waiting

• progress

In the context of process scheduling, what does the term 'context switch' refer to?

• Terminating a process that has completed execution

• Loading a process from disk into memory

• Changing the state of a process from running to waiting

• Switching the CPU from one process to another

Critical Section is

• local variable

• Global variable

• function parameter

What is the purpose of the wait queue in process scheduling?

• It contains processes that are waiting for CPU time

• It manages processes that have been terminated

• It stores processes that are waiting for I/O operations

• It holds processes that are ready to execute

What does the term 'process starvation' refer to in scheduling?

• A process that is terminated by the system

• A process that is currently executing

• A process that has completed execution

• A process that is waiting indefinitely for CPU time
