Introduction to Computer Engineering MCQs (Part-7)
What is the primary purpose of an operating system (OS)?
A Write code
B Display output
C Execute programs
D Control hardware resources
The operating system (OS) is responsible for managing hardware resources such as the CPU, memory, and input/output devices. It acts as an intermediary between software applications and hardware components, ensuring smooth operations.
Which of the following is an example of system software?
A Operating System
B Spreadsheet
C Word Processor
D Web Browser
System software includes essential programs like the operating system (OS), which manages computer hardware and provides an environment for running application software. It helps in managing resources and running tasks efficiently.
What does a CPU primarily do in a computer system?
A Manage networks
B Display graphics
C Perform calculations
D Store data
The CPU (Central Processing Unit) is responsible for executing instructions and performing calculations. It is the primary processing unit in a computer, handling operations such as arithmetic, logic, and data manipulation.
What is the role of memory management in an operating system?
A Store data permanently
B Allocate resources to software
C Control hardware devices
D Handle input/output tasks
Memory management is a key function of the operating system that ensures optimal allocation and deallocation of memory to various processes. It helps prevent memory conflicts and ensures efficient utilization of system resources.
Which of the following is the first step in problem solving in computing?
A Test the solution
B Analyze results
C Implement solution
D Define the problem
In problem solving, the first step is to define the problem clearly. This involves understanding the issue, identifying its constraints, and establishing goals. A well defined problem leads to more effective solutions and programming logic.
What does “booting” refer to in computing?
A Starting up a computer
B Shutting down the system
C Running a program
D Installing software
Booting refers to the process of starting a computer. During booting, the operating system is loaded into memory, and the computer is initialized to be ready for use. This can be a cold or warm boot, depending on the situation.
Which of these is an essential feature of an operating system?
A Perform calculations
B Create software
C Manage hardware resources
D Connect to networks
One of the most essential functions of an operating system is to manage hardware resources, including CPU, memory, and peripheral devices. It provides a stable environment for software applications to run smoothly and efficiently.
What does the term “virtual memory” refer to?
A Memory used by external devices
B Memory that simulates additional RAM
C Memory stored on a hard drive
D Memory that can be upgraded
Virtual memory is a technique that allows the operating system to use hard drive space to simulate additional RAM. This helps the computer handle larger tasks than would fit in physical memory, improving multitasking performance.
What is the main function of the file system in an operating system?
A Store user data
B Control hardware
C Run applications
D Execute programs
The file system in an operating system is responsible for managing how data is stored and retrieved. It organizes files and directories, making it easier for users and applications to access and manipulate data on storage devices.
Which component is responsible for handling input and output operations in a computer?
A Operating system
B Memory
C I/O controller
D CPU
The Input/Output (I/O) controller manages the communication between the computer’s internal components and external devices (such as a keyboard, mouse, or printer). It ensures that data is properly transferred between devices and the computer.
What is the role of the kernel in an operating system?
A Run applications
B Handle hardware communication
C Manage files
D Store user data
The kernel is the core part of the operating system that manages communication between the hardware and software. It controls tasks such as memory management, process scheduling, and input/output operations, ensuring smooth system operation.
Which of the following is an example of application software?
A Operating system
B Network protocol
C Database management system
D Word processor
A word processor (e.g., Microsoft Word) is an application software that allows users to create, edit, and format text based documents. Unlike system software, application software is designed to help users perform specific tasks.
What is the key difference between system software and application software?
A System software is essential, application software is optional
B System software is more complex
C Application software controls hardware
D System software is installed by users
System software includes operating systems and utilities that manage hardware resources, while application software includes programs designed to perform specific tasks for the user, such as word processing or web browsing.
What does the term “multitasking” refer to in computing?
A Storing large amounts of data
B Using multiple devices at once
C Running multiple programs simultaneously
D Running a single program for a long time
Multitasking refers to the ability of an operating system to execute multiple programs at the same time. This allows users to switch between tasks or run background processes while actively using a program.
What is a key characteristic of a problem solving approach in computing?
A Focus on data processing
B Create algorithms to solve problems
C Use graphical interfaces
D Focus only on hardware
A key part of problem solving in computing is creating algorithms. Algorithms are step by step instructions used to solve problems efficiently. They help break down complex issues into smaller, manageable steps for the computer to execute.
