Question 1

In active multiprogramming,each program is allowed to use only a preset amount of CPU time before it is interrupted so another job can begin its execution.The interrupted job resumes execution at some later time.This idea is called ____.
A) shared processing
B) CPU sharing
C) time slicing
D) distributed processing

Accepted Answer

This concept is known as time slicing, where the CPU time is sliced or divided between multiple programs in a round-robin fashion. Each program is allowed to use the CPU for a specified amount of time before being interrupted and allowing the next program to use the CPU. This technique improves the overall efficiency of the system by minimizing idle time and maximizing the utilization of the CPU. Shared processing and CPU sharing are similar concepts that refer to multiple programs sharing the same physical CPU. Distributed processing refers to a system in which processing tasks are distributed across multiple computers or nodes.

A) multiprogramming
B) multimedia
C) networking
D) multicore

Accepted Answer

The development of multicore technology refers to equipping a single chip with two or more processor cores. Multiprogramming, multimedia, and networking technologies do not necessarily relate to multiple processor cores on a single chip.

Question 4

The ____ is often very different from one operating system to the next,sometimes even between different versions of the same operating system.
A) User Interface
B) Process Manager
C) Memory Manager
D) File Manager

Accepted Answer

The user interface (UI) is what the user interacts with and how they perform tasks and navigate through the operating system. The UI can vary greatly between different operating systems and even different versions of the same operating system. The process manager, memory manager, and file manager are all components of the operating system but their functionality is more standardized and less dependent on the specific operating system or version.

Question 5

____ allows separate partitions of a single server to support different operating systems.
A) Multiprocessing
B) Multithreading
C) Virtualization
D) Shared processing

Accepted Answer

Virtualization allows for multiple virtual machines (VMs) to run on a single physical server, with each VM having its own operating system, applications, and resources. This allows for more efficient use of hardware resources and can simplify management and deployment of multiple systems. Multiprocessing refers to a system with multiple CPUs or cores, while multithreading refers to the ability of a single program to perform multiple tasks concurrently. Shared processing is not a commonly used term in the context of server computing.

Question 6

There are two types of real-time systems depending on the consequences of missing the deadline.A ____ real-time system risks total system failure if the predicted time deadline is missed.
A) constrained
B) restricted
C) soft
D) hard

Accepted Answer

A hard real-time system has a strict deadline and missing it can lead to total system failure. The other options (constrained, restricted, and soft) do not have such severe consequences for missing a deadline.

Question 7

The efficiency of a batch system is measured in ____,which is the number of jobs completed in a given amount of time.
A) processes
B) threads
C) throughput
D) turnaround time

Accepted Answer

Throughput is the correct choice as it measures the efficiency of a batch system by the number of jobs completed in a given amount of time. Processes and threads are not directly related to measuring the efficiency of a batch system, and turnaround time is a measure of how long it takes for a job to complete from the time it enters the system to the time it is finished.

Question 8

____ is where the data and instructions of a computer must reside to be processed.
A) CPU
B) Main memory
C) Read-only memory
D) I/O memory

Accepted Answer

Main memory, also known as RAM (Random Access Memory), is where the data and instructions of a computer must reside to be processed. The CPU fetches data and instructions from main memory to process them. While other types of memory like Read-only memory (ROM) and I/O memory are important, they do not serve this specific purpose.

Question 9

The name for the core portion of an operating system is the ____.
A) manager
B) center
C) nucleus
D) kernel

Accepted Answer

The kernel is the central component of most operating systems, responsible for managing system resources and providing low-level services to other parts of the operating system.

Question 10

The ____ uniquely identifies each resource,starts its operation,monitors its progress,and,finally,deallocates it,making the operating system available to the next waiting process.
A) Device Manager
B) File Manager
C) Keyboard Manager
D) Memory Manager

Accepted Answer

The Device Manager uniquely identifies each resource, starts its operation, monitors its progress, and finally deallocates it, ensuring the operating system is available for the next process. This role is crucial in managing hardware devices and their interactions with the software.

Question 11

A ____ chip holds software that is used to start the computer.
A) RAM
B) ROM
C) CPU
D) buffer

Accepted Answer

The ROM chip (Read-Only Memory) contains software that is used to start up the computer. This software is often referred to as the BIOS (Basic Input/Output System) which is responsible for initializing and configuring various hardware components such as the CPU (Central Processing Unit), RAM (Random Access Memory), and storage devices.

Question 12

____ systems are used in time-critical environments where reliability is key and data must be processed within a strict time limit.
A) Embedded
B) Hybrid
C) Interactive
D) Real-time

Accepted Answer

Real-time systems are specifically designed to process and analyze data within a strict time frame, making them critical in time-sensitive environments where reliability and accuracy are paramount. These systems are used in industries such as aviation, defense, and healthcare to ensure that critical information is processed and acted upon in real-time.

Question 13

A system with ____ divides programs into parts and keep them in secondary storage,bringing each part into memory only as it is needed.
A) virtual memory
B) shared memory
C) segmented processing
D) passive multiprogramming

Accepted Answer

This is the definition of virtual memory, where parts of a program are stored in secondary storage and brought into memory as needed. Shared memory refers to a memory space that is shared between multiple processes, segmented processing refers to dividing memory into segments for specific functions, and passive multiprogramming is not a commonly used term.

Question 18

The most common mechanism for implementing multiprogramming was the introduction of the ____ concept,whereby the CPU was notified of events needing operating systems services.
A) paging
B) sharing
C) messaging
D) interrupt

Accepted Answer

The most common mechanism for implementing multiprogramming is the use of interrupts. Interrupts are signals sent by hardware or software to the processor to stop the current task and switch to a higher-priority task. This allows the operating system to provide services to multiple programs simultaneously. Paging refers to the management of virtual memory, sharing refers to the sharing of resources among different programs, and messaging refers to the passing of information between programs. None of these concepts directly address the issue of implementing multiprogramming.
