What is an operating system?

• An operating system is a physical component of a computer.

• An operating system is a type of computer virus.

• An operating system is a type of computer game.

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

What are the main functions of an operating system?

• Manage computer resources, provide a user interface, facilitate communication, and coordinate tasks.

• Create and edit documents, manage files and folders, and install software.

• Play video games, browse the internet, and send emails.

• Store and retrieve data, control hardware devices, and perform mathematical calculations.

What is a device driver?

• A device driver is a software program that allows the operating system to communicate with a specific hardware device.

• A device driver is a physical component that connects a hardware device to the computer.

• A device driver is a program that allows hardware devices to communicate with each other.

• A device driver is a type of malware that can damage hardware devices.

Why are device drivers important in a computer system?

• They slow down the computer system.

• They are only necessary for outdated hardware.

• They allow the operating system to communicate and interact with hardware devices.

• They are not necessary for software installation.

What is memory management?

• The process of organizing files on a computer

• The process of controlling and coordinating computer memory

• The process of optimizing computer performance

• The process of managing computer peripherals

What are the different memory management techniques used in operating systems?

• FIFO, LRU, and LFU

• Binary Search, Linear Search, and Hashing

• Stack, Heap, and Cache

• Paging, Segmentation, and Virtual Memory

What is process scheduling?

• Method by which the operating system decides the order in which processes are executed on a computer system

• The process of installing new software on a computer system

• The process of terminating a running program on a computer system

• Method by which the operating system decides the order in which processes are executed on a computer network

What are the different process scheduling algorithms used in operating systems?

• First-Come, First-Served (FCFS), Shortest Job Next (SJN), Priority Scheduling, Round Robin (RR), Multilevel Queue Scheduling, and Multilevel Feedback Queue Scheduling.

• First-Come, First-Served (FCFS), Shortest Job Next (SJN), Priority Scheduling, Round Robin (RR)

• First-Come, First-Served (FCFS), Shortest Job Next (SJN), Priority Scheduling, Round Robin (RR), Multilevel Queue Scheduling.

• First-Come, First-Served (FCFS), Shortest Job Next (SJN), Priority Scheduling, Round Robin (RR), Multilevel Queue Scheduling, and Multilevel Feedback Queue Scheduling.

What is the difference between preemptive and non-preemptive scheduling?

• Preemptive scheduling allows interruptions, while non-preemptive scheduling does not.

• Preemptive scheduling allows interruptions, while non-preemptive scheduling allows for parallel execution.

• Preemptive scheduling does not allow interruptions, while non-preemptive scheduling allows interruptions.

• Preemptive scheduling allows interruptions, while non-preemptive scheduling allows interruptions.

What is the purpose of a context switch in process scheduling?

• The purpose of a context switch in process scheduling is to prioritize certain processes over others.

• The purpose of a context switch in process scheduling is to save the current state of a process and restore it later.

• The purpose of a context switch in process scheduling is to allow multiple processes to share the CPU and ensure fairness and efficiency in process execution.

• The purpose of a context switch in process scheduling is to increase the overall processing speed of the CPU.
