Which is an example of an operating system with only a command-line interface?
Answer:
An example of an operating system with only a command-line interface is DOS (Disk Operating System). DOS was one of the early operating systems for personal computers and is known for its text-based command-line interface. Users interact with the system by typing commands rather than using a graphical user interface (GUI). DOS was widely used in the 1980s and early 1990s before graphical operating systems like Windows became more prevalent. Despite its simplicity compared to modern operating systems, DOS is still used for some specialized applications and embedded systems where a lightweight and efficient operating system is required.
