Computer-related contributions

  • Invented the datagram and designed an early packet communications network. His work influenced others in the development of TCP/IP protocols used by the Internet.
  • Having participated in the design of the CTSS (Compatible Time Sharing System), Pouzin wrote a program called RUNCOM in 1963 or 1964. RUNCOM permitted the execution of contained commands within a folder, and can be considered the ancestor of the command-line interface and shell scripts. Pouzin was, in fact, the one who coined the term shell for a command language in 1964 or 1965.
