    Study Notes

    Operating System Functions

    • The main function of an operating system is to act as an intermediary between the user and the computer hardware.
    • The operating system presents the user with an equivalent machine or virtual machine.

    Multiplexing

    • Time Multiplexing ensures that each process is given time to utilize a resource one after the other.
    • Resources that can be shared using Time Multiplexing include CPU processing power, GPU, keyboard, and printers.
    • Space Multiplexing allows multiple programs to run simultaneously, allocating resources to each process at the same time.
    • In Space Multiplexing, RAM accommodates all the processes it can take at the same time.

    Operating System Components

    • The User Command Interface (also known as OS Shell) provides a way to access data in the computer.
    • The component of the operating system that deals with the proper scheduling of tasks in utilizing the processor or CPU is the Scheduler.
    • The Memory Manager focuses on the proper allocation of memory resources.
    • The Device Manager is responsible for handling sharing issues and exchange of data between devices.

    Operating System Types

    • A Single-User OS is capable of handling demands of a single user at a time.
    • A Real-Time OS makes use of time as a key parameter to its operation, distinguishing it from other types of operating systems.
    • An Embedded OS is designed to handle demands of a specific application or device.

    Operating System Generations

    • The First Generation of operating systems introduced the concept of Multiprogramming.
    • The Fourth Generation of operating systems is known for the development of graphical user interface (GUI).
