Deck 2: Operating System Overview

Question 1

Both batch processing and time sharing use multiprogramming.

Answer 3

A

Question 4

The user has direct access to the processor with a batch-processing type of OS.

Question 5

A monolithic kernel is implemented as a single process with all elements sharing the same address space.

Question 6

An OS should be constructed in such a way as to permit the effective development, testing, and introduction of new system functions without interfering with service.

Question 7

The OS frequently relinquishes control and must depend on the processor to allow it to regain control.

Question 8

A process consists of three components: an executable program, the associated data needed by the program, and the execution context of the program.

Question 9

The OS masks the details of the hardware from the programmer and provides the programmer with a convenient interface for using the system.

Question 10

Question 11

A special type of programming language used to provide instructions to the monitor is __________ .

A) FPL
B) JCL
C) DML
D) SML

Question 12

Uniprogramming typically provides better utilization of system resources than multiprogramming.

Question 13

The principle objective of Batch Multiprogramming is to minimize response time.

Question 14

D) API

Question 16

Virtualization technology enables a single PC or server to simultaneously run multiple operating systems or multiple sessions of a single OS.

Question 17

In a time sharing system, a user's program is preempted at regular intervals, but due to relatively slow human reaction time this occurrence is usually transparent to the user.

A) efficiency
B) ability to evolve
C) controlled access
D) convenience

Question 20

One of the driving forces in operating system evolution is advancement in the underlying hardware technology.

Question 21

A) time slicing
B) multithreading
C) round robin
D) clock cycle

Question 27

An __________ is a program that controls the execution of application programs and acts as an interface between applications and the computer hardware.

Question 28

Question 29

The __________ is the internal data by which the OS is able to supervise and control the process.

A) executable program
B) associated data
C) nucleus
D) execution context

Question 30

A __________ is set at the beginning of each job to prevent any single job from monopolizing the system.

Question 31

Two major problems with early serial processing systems were scheduling and __________ .
