The History of Operating Systems Marko Zivkovic Computer Science Department CS561 Illinois Institute of Technology 2014 What is an Operating System?

An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. Wikipedia Why do we need Operating

Systems? We have hardware, but how to control it? Mainframe computers Hardware Command Line Graphical User Interface Where everything started? Mainframes (1950)

Primitive conceptions of Operating Systems Punching Cards (1725) Magnetic Tapes (1950) Programs Done or Crash Alan Turning

IBM 7090 Mainframe First Real Operating System is ? GM-NAA I/O, produced in 1956 by General Motors Research Division

System/360 computers with OS/360 and DOS/360 Operating System blossom Scope, MACE, Kronos, EXEC, MCP, etc. (1960 -1967) More Operating Systems Plato System in late 1970s (Real Time Chat)

Multics MIT (Security Levels) UNIX OS, Bell Labs (1960, portable, in C, main OS for Bell Labs) MOS home computers, 8bit Commodore 64, Atari, Apple II Series, Spectrum 1980 (8 bit home comps)

Geos, CP/M (The most successful at that time) The invention of Microprocesors Inexpensive, Interchangeable components Widespread and Start of PC era MSDOS 1.0 Microsoft and IBM-PC (1981) 16 bit, X Window OS Unix like (since cost of components deceased) GUI
