This operating software consists of a user friendly interface and is dominating the global market in the present times. • It is responsible for the management … A command-line interface (CLI) processes commands to a computer program in the form of lines of text.The program which handles the interface is called a command-line interpreter or command-line processor.Operating systems implement a command-line interface in a shell for interactive access to operating system functions or services. One of the jobs of the operating system is to provide a 'user interface', so that a human can communicate with the hardware that makes up a computer. Examples of Operating System . The user interface (UI) is the point of human-computer interaction and communication in a device.
