Understanding Operating Systems

What is an operating system?

• A type of computer hardware

• A programming language

• An operating system is software that manages computer hardware and software resources.

• A web browser

Name three popular operating systems.

• Android

• iOS

• Chrome OS

• Microsoft Windows, macOS, Linux

What is the primary function of an operating system?

• To run applications without user input

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

• To store data permanently

• To provide internet connectivity

What is the difference between a kernel and a shell?

• The kernel is a type of shell.

• The shell manages system resources; the kernel provides user interaction.

• The kernel manages system resources; the shell provides user interaction.

• The kernel is only used for programming, while the shell is for system administration.

What is multitasking in operating systems?

• Multitasking is when an operating system only allows background processes to run.

• Multitasking refers to the process of shutting down all other tasks to focus on one.

• Multitasking is the ability to run a single task at a time.

• Multitasking is the capability of an operating system to manage and execute multiple tasks or processes concurrently.

Define the term 'process' in the context of operating systems.

• A process is a type of hardware component in a computer.

• A process is a user interface for interacting with the operating system.

• A process is an instance of a program in execution, including its code, current activity, and allocated resources.

• A process refers to the storage space allocated for data.

What is virtual memory?

• Virtual memory is a hardware component in computers.

• Virtual memory is a type of physical memory.

• Virtual memory is a technique for increasing CPU speed.

• Virtual memory is a memory management technique that uses disk space to extend the apparent amount of RAM available to applications.

Explain the concept of file systems.

• A file system is a protocol for transferring files over the internet.

• A file system is a hardware component that physically stores data on a disk.

• A file system is a method for organizing and managing files on storage devices, defining how data is stored, accessed, and retrieved.

• A file system is a type of software application for editing text files.

What is the role of device drivers in an operating system?

• Device drivers facilitate communication between the operating system and hardware devices.

• Device drivers provide security features for the operating system.

• Device drivers are used to enhance the graphical user interface.

• Device drivers are responsible for managing system memory.

How do operating systems manage hardware resources?

• Operating systems manage hardware resources by ignoring user input and preferences.

• Operating systems manage hardware resources solely through user commands.

• Operating systems manage hardware resources through allocation, scheduling, and abstraction.

• Operating systems manage hardware resources through encryption and compression.
