Operating system of a computer
Operating system of a computer Provides a layer, user friendly interface.
Operating system and user interface. As already mentioned, in addition to the hardware, a computer also needs a set of programs—an operating system—to control the devices. Operating systems can be used with different user interfaces (UI): text user interfaces (TUI) and graphical user interfaces (GUI) as examples.
The operating system provides a user interface that enables you to interact with the computer. Unlike the command- and menu-driven interfaces used earlier, GUIs display graphics and use the point-and-click technology of the mouse and cursor, making the OS more user-friendly.
DOS (Disk Operating System) was the dominant operating system for microcomputers in the 1980s and the early 1990s. ... The DOS system used a command line, instead of a GUI (graphical user interface), to allow the user to navigate, open files, and perform other functions.
