Computer Fundamentals: Operating Systems

What is an operating system?

• An operating system is a type of internet browser.

• An operating system is a software that manages computer hardware and provides services for computer programs to run.

• An operating system is a type of software used for creating documents.

• An operating system is a type of hardware used in computers.

Name two popular operating systems used in personal computers.

• Windows, macOS

• Android

• iOS

Explain the difference between multitasking and multiprogramming in the context of operating systems.

• Multitasking involves executing multiple programs simultaneously, while multiprogramming involves executing a single program at a time.

• In multitasking, only one task is executed at a time, while in multiprogramming, multiple tasks are executed simultaneously.

• In multitasking, multiple tasks are executed simultaneously by rapidly switching between them, while in multiprogramming, multiple programs are loaded in memory but only one program is executed at a time.

• Multitasking and multiprogramming are interchangeable terms in the context of operating systems.

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

• Decides what color theme to use

• Plays music in the background

• Manages system resources and provides essential services for the operating system.

• Makes coffee for the users

Discuss the importance of device drivers in an operating system.

• Device drivers are responsible for managing the user interface of the operating system.

• Device drivers are only needed for software applications, not the operating system.

• Device drivers are not necessary as hardware devices can function independently from the operating system.

• Device drivers are crucial in enabling the operating system to interact with hardware devices by translating high-level commands into low-level instructions.
