PC-DOS

PC-DOS (Personal Computer Disk Operating System) is an early software that manages a computer's hardware and files, enabling users to run applications and communicate with the machine. It provides essential functions like opening, saving, and organizing files, as well as managing hardware components like the keyboard, screen, and storage devices. Developed by Microsoft for IBM PCs in the 1980s, PC-DOS served as the foundational operating system for early personal computers, offering a command-line interface where users input text commands to perform tasks. It laid the groundwork for modern operating systems, emphasizing simplicity and direct hardware control.
