Understanding Operating Systems

What is an operating system?

• A network protocol for data transmission.

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

• A type of computer hardware component.

• A programming language used for software development.

Name three functions of an operating system.

• Data storage

• Network management

• 1. Resource management 2. User interface 3. Application execution

• File encryption

What is the difference between system software and application software?

• System software is only for mobile devices.

• System software is designed for gaming purposes.

• System software manages hardware; application software performs user-specific tasks.

• Application software is used to manage hardware resources.

What is a kernel in an operating system?

• The kernel is a hardware component that stores data permanently.

• The kernel is a type of software application for word processing.

• The kernel is the central part of an operating system that manages system resources and communication between hardware and software.

• The kernel is a user interface for interacting with the operating system.

Explain the term 'multitasking' in the context of operating systems.

• Multitasking refers to the ability of a computer to run a single process at a time.

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

• Multitasking is when an operating system shuts down unused applications to save resources.

• Multitasking means an operating system can only handle one user at a time.

What are the two main types of operating systems?

• Desktop Operating Systems and Server Operating Systems

• Cloud Operating Systems and Virtual Operating Systems

• Real-Time Operating Systems and Network Operating Systems

• Mobile Operating Systems and Embedded Operating Systems

Define the term 'user interface' in relation to operating systems.

• A user interface refers to the physical components of an operating system.

• A user interface is a type of hardware used in computers.

• A user interface is the software that manages system resources.

• A user interface in operating systems is the medium through which users interact with the system, encompassing graphical and command-line elements.

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

• To manage the user interface of the operating system.

• The purpose of device drivers in an operating system is to enable communication between the OS and hardware devices.

• To provide security features for the operating system.

• To optimize the performance of the operating system.

How does an operating system manage memory?

• An operating system manages memory by deleting unused files.

• An operating system manages memory by storing all data on external hard drives.

• An operating system manages memory by compressing all data into a single file.

• An operating system manages memory by allocating, tracking, and protecting memory for processes, using techniques like paging and segmentation.

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

• The file system controls the CPU's processing speed.

• The file system handles user interface design.

• The file system is responsible for managing network connections.

• The file system organizes, stores, and manages data on storage devices.
