Question 1

Multi-programming requires a _______ operating-system.&#10;A) batch&#10;B) time-sharing&#10;C) parallel&#10;D) distributed

Accepted Answer

Multi-programming involves running multiple programs simultaneously on a single processor. This requires an operating system that can allocate processor time efficiently between multiple programs, which is provided by a time-sharing operating system. Batch operating systems are designed to process a large volume of similar jobs without user interaction. Parallel operating systems are used in distributed computing environments where multiple processors work together on a single task.

Question 2

_______ is multi-programming without swapping.&#10;A) Partitioning&#10;B) Virtual memory&#10;C) Demand paging&#10;D) Queuing

Accepted Answer

Partitioning is the technique of dividing the memory into fixed partitions and allocating each partition to a different program. Multi-programming without swapping means that only one program will be executed at a time in each partition without swapping between them. Virtual memory involves swapping programs between memory and disk, demand paging involves loading only the required parts of a program into memory, and queuing is a scheduling technique for processes.

Question 3

A process in the ready state goes to the running state when _______.&#10;A) it enters memory&#10;B) it requests I/O&#10;C) it gets access to the CPU&#10;D) it finishes running

Accepted Answer

A process in the ready state goes to the running state when it gets access to the CPU. When the CPU scheduler selects a process from the pool of ready processes, it moves the selected process into the running state and starts executing it on the CPU.

Question 4

_______ is multi-programming with swapping.&#10;A) Partitioning&#10;B) Paging&#10;C) Demand paging&#10;D) Queuing

Accepted Answer

Demand paging is a method of swapping where pages of data are loaded into memory on demand, which is essentially a form of multi-programming that allows for more efficient use of memory.

Question 5

_______ supervises the activity of each component in a computer system.&#10;A) An operating system&#10;B) Hardware&#10;C) A queue&#10;D) An application program

Accepted Answer

An operating system is responsible for supervising the activity of each component in a computer system, including hardware, applications programs, and queues. It manages system resources such as memory, CPU, input/output devices, and networking functions.

Question 6

In _______, the program can be divided into equally sized sections called pages, but the pages need not be in memory at the same time for execution.&#10;A) partitioning&#10;B) paging&#10;C) demand paging&#10;D) demand segmentation

Accepted Answer

Demand paging allows programs to be divided into pages that are loaded into memory only as needed, not requiring all pages to be in memory simultaneously for execution.

Question 7

The _______ scheduler moves a process from one process state to another.&#10;A) job&#10;B) process&#10;C) virtual&#10;D) queue

Accepted Answer

The process scheduler is responsible for moving a process from one process state to another in the operating system. Job scheduler is responsible for scheduling batch jobs. Virtual scheduler is not a common term in operating systems. Queue scheduler doesn't exist as a separate type of scheduler, it is usually implemented in combination with other schedulers.

Question 8

In paging, a program is divided into equally sized sections called _______.&#10;A) pages&#10;B) frames&#10;C) segments&#10;D) partitions

Accepted Answer

In paging, a program is divided into equally sized sections called pages. Frames are the equally sized sections of memory used by the operating system to store pages. Segments are larger sections of a program that are not necessarily equal in size, and partitions refer to the division of physical memory into sections.

Question 9

_______ can occur if a process has too many resource restrictions.&#10;A) Starvation&#10;B) Synchronization&#10;C) Paging&#10;D) Deadlock

Accepted Answer

Starvation occurs when a process is unable to access a required resource due to too many restrictions imposed on it by the operating system. This can result in the process being unable to proceed, while other processes continue to run.

Question 10

A program becomes a _______ when it is selected by the operating system and brought to the hold state.&#10;A) job&#10;B) process&#10;C) deadlock&#10;D) partition

Accepted Answer

When a program is selected by the operating system and brought to the hold state, it becomes a job. This is the initial step before it is further processed or executed.

Question 11

The _______ manager is responsible for archiving and backup.&#10;A) memory&#10;B) process&#10;C) device&#10;D) file

The answer of The _______ manager is responsible for archiving...

Question 12

_______ is a multi-programming method in which multiple programs are entirely in memory with each program occupying a contiguous space.&#10;A) Partitioning&#10;B) Paging&#10;C) Demand paging&#10;D) Demand segmentation

The answer of _______ is a multi-programming method in which...

Question 13

The _______ scheduler creates a process from a job and changes a process back to a job.&#10;A) job&#10;B) process&#10;C) virtual&#10;D) queue

Accepted Answer

Question 14

The _______ manager is responsible for access to I/O devices.&#10;A) memory&#10;B) process&#10;C) device&#10;D) file

Accepted Answer

Question 15

To prevent _______, an operating system can put resource restrictions on processes.&#10;A) starvation&#10;B) synchronization&#10;C) paging&#10;D) deadlock

Accepted Answer

The answer of To prevent _______, an operating system can...

Question 16

_______ is a program that facilitates the execution of other programs.&#10;A) An operating system&#10;B) Hardware&#10;C) A queue&#10;D) An application program

Accepted Answer

Question 17

In _______, the program can be divided into differently sized sections.&#10;A) partitioning&#10;B) paging&#10;C) demand paging&#10;D) demand segmentation

Question 18

A process in the _______ state can go to either the ready, terminated, or waiting states.&#10;A) hold&#10;B) virtual&#10;C) running&#10;D) hold or running
