TYPES OF OPERATING SYSTEMS

                 There are various types of operating systems, each with its own specific features. They can be
                 grouped based on how they control the computer and the types of applications they support.
                 Let’s take a quick look at the different types of operating systems.

                    Single-user Operating System: This type of operating system allows only one person to use
                    the computer at a time. An example of a single-user operating system is DOS. It’s like having
                    a computer that only one person can use at once, which was common in older computers.

                    Multi-processing Operating System: This type of operating system uses more than one
                    CPU to manage the computer's tasks. The CPUs work together to improve performance and
                    allow  the  computer  to  run  multiple processes concurrently.  For example, modern  servers
                    and high-performance computing systems often use multi-processing operating systems to
                    efficiently manage a large number of tasks.
                    Multi-tasking Operating System: A multi-tasking operating system allows you to perform

                    several tasks at the same time, such as browsing the web while listening to music. All tasks
                    share the CPU’s processing power, and you can switch between them as needed. Common
                    examples include Windows 11, macOS, UNIX, and various Linux distributions. These systems
                    can handle multiple applications and processes simultaneously.

                    Multi-user Operating System: This type of operating systems allow multiple users to access
                    and use a single computer simultaneously. This is achieved by creating separate user accounts
                    for each individual, ensuring that their data and activities remain private. For example, in
                    schools or offices, multiple users can work on the same system.
                    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.
                    Distributed  Operating System: This type  of operating  system  manages a  group  of

                    independent computers as if they were a single system. These computers can be geographically
                    distributed and interconnected  through  a network.  It allows multiple  computers to share
                    resources like memory and processing power.

                    WHAT IS A USER INTERFACE?

                 A User Interface (UI) is the part of an operating system that lets you interact with the computer. It
                 includes commands, menus, and icons that make it easier to use the computer. A well-designed
                 UI makes  the operating  system  not only look good but also simple  and easy to use. With
                 advancements in technology, modern UIs often include touch gestures, voice commands, and
                 even virtual assistants like Siri or Google Assistant, making interaction even simpler. There are
                 two main types of user interfaces: Character User Interface (CUI) and Graphical User Interface
                 (GUI). Let’s explore these in more detail.
