The document introduces operating systems and their history. It discusses what an operating system is, providing examples of how it hides hardware details and manages resources. It then summarizes the history of operating systems from first to fourth generations, describing characteristics of batch processing systems and the introduction of multiprocessing. The document also categorizes different types of operating systems and reviews basic computer hardware components like CPUs, memory, disks, and buses, describing their functions.

- 3. 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 KCD - Sistem Operasi http://fasilkom.narotama.ac.id/ 3
- 4. 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 KCD - Sistem Operasi http://fasilkom.narotama.ac.id/ 4
- 5. 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 KCD - Sistem Operasi http://fasilkom.narotama.ac.id/ 5
