COMP 2: Topic 6 OS: Interrupts and Scheduling Retrieval Quiz

A message sent by the OS to change the CPU schedule is known as...

• Interrupt

• Cache

• Polling

• Time Slicing

Processor scheduling is one of the functions managed by the OS.  Which one is a scheduling method used by the scheduler

• Round To It

• Round Robin

• Shortest Quickest Time

• Round Table

Which of the following is a segment of memory or storage, such as the disk in the accompanying figure, in which items are placed while waiting to be transferred from an input device or to an output device?

• Process

• Index

• Buffer

• Threading

What is the purpose of memory management?

• To store data in the most efficient manner

• To start the computer and operating system quickly

• To optimise the use of RAM

• To allocate system resources stored in the ROM

Round Robin is also known as

• Merry go round

• Time slicing

• Polling

• Time sharing

What is the main part of the operating system?

• Memory Management

• Security

• Operating system software

• Kernel

Why might the first come first serve scheduling method not be efficient?

• Once a job starts it prevents other jobs from being processed

• Not all tasks will be allocated processor time

• Some tasks will get discarded because the processor is working on a task taking a long time

• It is fast and therefore efficient

Why is scheduling necessary? Select all that you think apply...

• Process as many jobs as possible… …in least possible time / quicker

• Prevents stress on the computing components such as the CPU, Memory and Storage

• Provides efficient use of resources and processor time

• Ensure all jobs are processed (fairly)

Which scheduling algorithm am I? Jobs are executed as they are implemented...

• Round Robin

• First Come First Serve

• Just in Time

• Shortest Time Remaining

Which scheduling algorithm am I? This has the advantage that if the CPU time of the program is known, as it runs smaller jobs quickly.

• First Come First Served

• Round Robin

• Shortest Time Remaining

• Shortest Job First
