    Study Notes

    Multiple Choice Questions (MCQs) on Operating Systems

    • Operating System Function: The primary function of an operating system is to manage hardware resources, execute user programs, and provide a user interface.
    • Computer System Components: Hardware, Operating System, and Application Programs are components of a computer system. Network protocols are not a component of the core system.
    • Multiprogramming: Multiprogramming allows an operating system to run multiple applications on a single CPU by organizing jobs so the CPU is always executing something.
    • Process Definition: A process is a program in execution.
    • Memory Management: Memory management is a crucial function in an operating system to track memory usage.
    • Real-time Operating System Characteristic: A real-time operating system is characterized by well-defined fixed time constraints. It does not need extended user interaction.
    • Virtual Memory: Virtual memory allows execution of processes that are not completely in memory. This technique utilizes memory for caching to speed things up.
    • Cloud Computing Service Model: Software as a Service (SaaS) is a cloud computing service model.
    • Device Driver Role: A device driver provides a uniform interface between the controller and operating system kernel.
    • Asymmetric Multiprocessing: In asymmetric multiprocessing, each processor is assigned a specific task.
    • Interrupt Definition: An interrupt is a signal to the CPU indicating an event needing immediate attention, usually a hardware or software triggered event.
    • Open-Source Operating System Feature: Open-source operating systems are free to use and modify.
    • Kernel Purpose: The kernel is responsible for managing system resources.
    • Storage Management Types: Storage management in operating systems includes file management, memory allocation, and disk scheduling.
    • Bootstrap Program Function: The bootstrap program loads the operating system kernel at startup.
    • Timesharing Definition: Timesharing allows multiple users to interact simultaneously with the system.
    • Trap Definition: A trap is a software-generated interrupt caused by an error.
    • Multiprocessor System Benefit: Increased throughput is a benefit of using multiprocessor systems.
    • I/O Management Function: I/O management handles input and output operations.
    • Secondary Storage Characteristic: Secondary storage provides large, non-volatile storage capacity.
    • Swapping Definition: Swapping moves data between main and secondary storage to improve memory efficiency.
    • Process Synchronization Methods: Mutexes, semaphores, and monitors are common methods for process synchronization in operating systems.
    • File System Purpose: A file system provides a way to store and retrieve files.
    • Network Operating System Example: Windows Server is a type of network operating system.
    • Distributed Operating System Advantage: Improved resource sharing is a key benefit of distributed operating systems.
    • Peer-to-Peer Network Characteristic: In a peer-to-peer network, all nodes can act as both clients and servers.
    • Virtual Machine Manager (VMM) Function: A VMM provides virtualization services by creating virtual machines that can run on the same hardware.
    • Real-Time OS Example: VxWorks is an example of a real-time operating system (RTOS)
    • Cache Function: A cache speeds up data access by storing frequently used data.
