Scheduling Algorithms

Question 1

types of scheduling algorithms

Answer 1

FCFS, SJF, Priority scheduling, Round Robin

Question 2

goals of scheduling

Answer 2

maximum CPU utilization, Minimum turn-around time, minimum wait time, minimum response time, maximum throughput.

Question 3

TAT

Answer 3

the time taken for the first process into the ready state till it terminates.

Question 4

response time

Answer 4

time taken between the process in ready queue and when it is allocated the CPU.

Question 5

wait time

Answer 5

the time process waits for CPU.

Question 6

Multi-level queue and Multi-level feedback queue

Answer 6

In both of these the queue is divided into multiple levels and each level have their own scheduling algorithms but in multi-level queue the system process and highest priority are kept first.
but in feedback queue the one’s which taken more time are kept in the last level.

Question 7

what is concurrency.

Answer 7

when multiple threads of a process are running parallelly it is known as concurrency.
