  Introduction…  An operatingsystem acts as an intermediary between the user of a computer and computer hardware .  The purpose of an operating system is to provide an environment in which a user can execute programs conveniently and efficiently.  It performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers. Windows - Versions : Windows 10 , 8 , 7 , XP, 98 Apple OS - Versions : Mojave, Catalina, Mac OS X Linux - Versions - Red Hat, KDE ....

  Functions of OperatingSystem…  Resource Management : When parallel accessing happens in the OS means when multiple users are accessing the system the OS works as Resource Manager, Its responsibility is to provide hardware to the user . It decreases the load in the system .  Process Management : It includes various tasks like scheduling, termination of the process . OS manages various tasks at a time . Here CPU Scheduling happens means all the tasks would be done by the many algorithms that use for scheduling .

  Continued…  Memory Management: Refers to the management of primary memory . The operating system has to keep track, how much memory has been used and by whom . It has to decide which process needs memory space and how much . OS also has to allocate and deallocate the memory space .  Security/Privacy Management : Privacy is also provided by the Operating system by means of passwords so that unauthorized applications can’t access programs or data . For example, Windows uses Kerberos authentication to prevent unauthorized access to data .  Device management in an operating system means controlling the Input/Output devices like disk, microphone, keyboard, printer, magnetic tape, USB ports, camcorder, scanner, other accessories, and supporting units like supporting units control channels .  File system is the part of the operating system which is responsible for file management . It provides a mechanism to store the data and access to the file contents including data and programs

  Window Operating System… Windows is a family of proprietary graphical user interface (GUI) operating systems developed by Microsoft for personal computers. It manages a computer's hardware and software, allowing users to run applications, manage files, and interact with the system through visual elements like icons and menus. Windows is the most popular operating system in the world and is preloaded on most new PCs.

  Linux Operating System… Linux is an open-source, Unix-like operating system kernel that is the foundation for many different operating systems called Linux distributions. It is known for being free, highly portable, and secure, running on a wide range of devices from personal computers and servers to smartphones and supercomputers. A key characteristic of Linux is its open-source nature, which allows for community collaboration and transparency in its development.

  •Batch Operating System: Processesjobs in groups without direct user interaction during execution. •Time-Sharing Operating System: Allows multiple users to access the same system resources simultaneously by rapidly switching between user tasks.
• 9.
  •Real-Time Operating System(RTOS): Designed for systems that require strict timing guarantees, like those in medical devices or industrial control systems. • Distributed Operating System: Manages a group of independent computers and makes them appear as a single system.
• 10.
  •Network Operating System: Managesand shares network resources, like files and printers, across a network of computers. •Multiprocessing Operating System: Uses multiple processors to perform tasks in parallel, increasing speed and performance • Multitasking Operating System: allows a computer to run multiple tasks or programs seemingly at the same time by rapidly switching the CPU's attention between them.
