Introduction to Operating Systems

What is the primary function of an operating system?

• To provide internet connectivity

• To store data permanently

• To run applications without user input

• The primary function of an operating system is to manage hardware and software resources.

Which of the following is a type of operating system structure?

• Monolithic

• Distributed

• Networked

• Real-time

What is a characteristic of a monolithic operating system?

• A microkernel design with minimal services.

• Single large kernel managing all system resources.

• Multiple small kernels working independently.

• A distributed system architecture.

Which type of operating system allows multiple users to access resources simultaneously?

• Single-user operating system

• Real-time operating system

• Embedded operating system

• Multi-user operating system

What is the main difference between closed source and open source operating systems?

• Closed source operating systems allow public access to their source code.

• The main difference is that closed source operating systems restrict access to their source code, whereas open source operating systems allow public access and modification of their source code.

• Open source operating systems are only available for Linux-based systems.

• Closed source operating systems are free to use, while open source are paid.

In a single processor system, how many CPUs are used?

• 4 CPUs

• 2 CPUs

• 1 CPU

• 8 CPUs

What does multitasking in an operating system refer to?

• Multitasking is the ability to run multiple operating systems on a single machine.

• Multitasking allows multiple processes to run concurrently in an operating system.

• Multitasking refers to the process of shutting down applications to save resources.

• Multitasking allows only one process to run at a time.

Which component of an operating system is responsible for managing hardware resources?

• user interface

• shell

• file system

• kernel

What is the role of the shell in an operating system?

• The shell provides a user interface for command execution and system management.

• The shell is responsible for hardware management.

• The shell compiles source code into executable files.

• The shell manages memory allocation for applications.

Which interface allows users to interact with the operating system using text commands?

• Touch Interface

• Graphical User Interface (GUI)

• Voice Command Interface

• Command Line Interface (CLI)
