Consoles vs Terminals vs Shells

  • consoles vs terminals/command line shells
    • console -> io device which is part of a computer (physical terminal)
      • console is the device: -> terminal is program inside that device
    • terminal -> text input output environment (can be remote)
      • windows terminal
    • shell -> program which the terminal/console sends input to which sends command to the OS
      • unix shell
      • powershell
      • cmd
      • bash, fish, zsh, ksh, sh, tsch

BREIF HISTORY

  1. At first only main console
  2. Then multiple terminals which allowed mulitple people to use one computer
  3. Graphics support
  4. Console + terminal merged
  5. Virtual terminals -> no need for direct hardware control -> replaced by OS
