label: Description
content: CP/M, originally stood for Control Program/Monitor but was later known as Control Program for Microcomputers. It was a mass-market operating system created for Intel 8080/85-based microcomputers. CP/M did not use subdirectories in its file structure – it used 16 numbered user areas (User 0 – 15) for organizing and storing files. This approach prevented the intermixing of files on a computer used by multiple users for multiple tasks. The concept had little relevance when storing files on a floppy disk; however, it was useful for microcomputers with hard drives.
