Introduction
• A computer system consists of
– hardware
– system programs
– application programs

What is an Operating System
• It is an extended machine
– Hides the messy details which must be performed
– Presents user with a virtual machine, easier to use
• It is a resource manager
– Each program gets time with the resource
– Each program gets space on the resource

History of Operating Systems (1)
Early batch system– bring cards to 1401– read cards to tape– put tape on 7094 which does computing– put tape on 1401 which prints output

History of Operating Systems (2)
• First generation 1945 - 1955
– vacuum tubes, plug boards
• Second generation 1955 - 1965
– transistors, batch systems
• Third generation 1965 – 1980
– ICs and multiprogramming
• Fourth generation 1980 – present
– personal computers
