  • Multitasking

    ,

    Explanation:Multitasking is an operating system feature that allows multiple processes to run concurrently by sharing the CPU. This enables the system to perform multiple tasks efficiently, improving user experience and system productivity. The two main types of multitasking are preemptive multitasking and cooperative multitasking. In preemptive multitasking, the operating system decides which process gets CPU…

  • Context Switching

    ,

    Context switching is the process of saving the state of a currently running process and loading the state of the next process to be executed. This allows multiple processes to share the CPU efficiently. Context Switching is the process of saving and restoring the state (or context) of a process or thread during execution, so…

  • Scheduling

    ,

    Scheduling in operating systems involves the efficient allocation of the CPU to processes. The objective is to maximize resource utilization, reduce waiting times, and ensure fair execution of all processes. Scheduling is the method by which an operating system decides which process or thread will be executed by the CPU at any given time. Formally,…

  • Memory Management

    ,

    Memory management is a core function of the operating system responsible for the allocation, deallocation, and optimization of primary memory (RAM). It ensures that processes have sufficient memory to execute while maximizing system efficiency and stability. Memory Management refers to the process by which an operating system manages computer memory, allocating it to processes and…

  • Process

    ,

    A process is a fundamental concept in operating systems (OS) representing a program in execution. It encompasses the program code, its current activity, and the necessary resources such as memory, files, and I/O devices required for its execution. Processes are dynamic entities that transition through various states, including new, ready, running, waiting, and terminated as…
