TYPES OF OPERATING SYSTEMS

                 Operating system can be categorised based on control and the applications they support.
                 Some of the important types of operating systems are as follows:

                    Single-User  Operating  System:  This type  of operating  system allows only one user to
                    access the computer system at a time. The most commonly used single-user operating system
                    is DOS.
                    Multiprocessing Operating System: A multiprocessing operating system uses more than one
                    Central Processing Unit (CPU) to manage the computer's functions. These CPUs communicate
                    with each other to coordinate  operations,  providing higher speed and the ability to run
                    multiple applications simultaneously.
                    Multi-Tasking Operating System: A multi-tasking operating system allows users to execute
                    multiple tasks on one computer simultaneously. All tasks share common processing resources
                    like the CPU. This type of operating system also allows for changing the priority of tasks
                    according to requirements. Common examples include Windows XP, Windows 7, Windows
                    10, UNIX, and Linux.
                    Multi-User Operating System: In this type of operating system, multiple users can access the
                    computer simultaneously. Examples include Linux and some versions of Windows.
                    Real-Time Operating System: This operating system is designed to do tasks quickly and
                    within a set time. It’s often used in machines, instruments, and industrial systems where timing
                    is crucial, like in robotics or automatic controls in factories.

                     WHAT IS A USER INTERFACE?

                 A User  Interface  (UI)  is a  part  of an  operating  system that  allows users to  interact  with  the
                 computer. It provides commands, menus, and icons that facilitate this interaction. An effective
                 interface enhances the attractiveness and user-friendliness of an operating system.
                 User interfaces can be divided into two categories based on their working environment:
                 Character User Interface (CUI)

                 A Character User Interface is a medium through which users interact with a computer using
                 text-based commands. Due to its reliance on commands, CUI is also known as a Command Line
                 Interface (CLI). This type of interface provides a command prompt where users can type commands
                 to perform specific tasks. Examples of CUI include DOS and Windows Command Prompt.

                                                                           Tech

                                                                             Funda

                                                                                          You can open the
                                                                                          Windows       Command
                                                                                          Prompt by pressing
                                                                                          the Windows Key + R.
                                                                                          The  Run dialog box
                                                                                          appears. Type cmd and
                                                                                          click on the OK button.
