Operating System - Practice Test

[#401] Which of the following is not true about documentation?

(A) Documentation, of a system, should be as clear and direct as possible

(B) Documentation increases the maintenance time and cost

(C) Documentation gives better understanding of the problem

(D) All of the above

Correct Answer

(B) Documentation increases the maintenance time and cost

Explanation

Solution: Documentation is any communicable material that is used to describe, explain or instruct regarding some attributes of an object, system or procedure, such as its parts, assembly, installation, maintenance and use. Documentation can be provided on paper, online or on digital or analog media, such as audio tape or CDs.

[#402] The system/370 assembler language

(A) allows the programmer to write base registers and displacements explicitly in the source program.

(B) is used to remember which of the general-purpose registers are currently available as base registers, and what base addresses they contain.

(C) allows multiple programs to reside in separate areas of core at the same time.

(D) is a term that refers to the control programs of an operating system.

Correct Answer

(A) allows the programmer to write base registers and displacements explicitly in the source program.

Explanation

Solution: The system/370 assembler language allows the programmer to write base registers and displacements explicitly in the source program.

[#403] Scheduling is

(A) allowing jobs to use the processor

(B) unrelated to performance consideration

(C) not required in uniprocessor systems

(D) the same regard-less of the purpose of the system

Correct Answer

(A) allowing jobs to use the processor

Explanation

Solution: The process scheduling is the activity of the process manager that handles the removal of the running process from the CPU and the selection of another process on the basis of a particular strategy. Process scheduling is an essential part of Multiprogramming operating systems.

[#404] What scheduling algorithm allows processes that are logical runnable to be temporarily suspended?

(A) preemptive scheduling

(B) non-preemptive scheduling

(C) FIFO

(D) FCFS

Correct Answer

(A) preemptive scheduling

Explanation

Solution: Preemptive Scheduling: A scheduling discipline is preemptive if, once a process has been given the CPU can taken away. The strategy of allowing processes that are logically runable to be temporarily suspended is called Preemptive Scheduling and it is contrast to the "run to completion" method.

[#405] In an absolute loading scheme, which loader function is accomplished by the loader

(A) Reallocation

(B) Allocation

(C) Linking

(D) Loading

Correct Answer

(D) Loading

Explanation

Solution: In an absolute loading scheme, Loading function is accomplished by the loader
