OS Basics

A process is a...

• program in execution
• program on the hard drive
• high level program
• low level program 

Keeping track of the location of processes in memory and allocating space to new processes is known as...

• Memory Management
• Process Management
• Memory Scheduling
• Process Scheduling

The primary purpose of an operating system is:

• To make the most efficient use of the computer hardware

• To allow people to use the computer,

• To keep systems programmers employed

• To make computers easier to use

The strategy of allowing processes that are logically runnable to be temporarily suspended is called

• preemptive scheduling

• non preemptive scheduling

• shortest job first

• first come first served

Which is not a process state?

• waiting

• terminated

• blocked

• redirected

What scheduling algorithm assigns the CPU

to the process with the highest priority?

• FIFO

• SJF non preemptive

• SJF preemptive

• priority

The interval from the line of submission of a process to the time of completion is termed as ____

• waiting time

• throughput

• turnaround time

• response time

The processes that are residing in main memory and are ready and waiting to execute are kept on a list called:

• job queue

• ready queue

• execution queue

• process queue

Scheduling is done so as to ____________

• increase CPU utilization

• decrease CPU utilization

• keep the CPU more idle

• none of the mentioned

What is Waiting time?

• the total time in the blocked and waiting queues

• the total time spent in the ready queue

• the total time spent in the running queue

• the total time from the completion till the submission of a process
