4. Learning Outcomes Pada akhir pertemuan ini, diharapkan mahasiswa akan mampu : • menyebutkan fungsi dan struktur sistem operasi (C1)

5. Outline Materi • Sistem komputer • Fungsi Sistem Operasi • Sejarah sistem Operasi • First generation • Second generation • Third generation • Fourth generation

6. FUNDAMENTALS OF OPERATING SYSTEMS DEFINITION AND COMPONENTS ²Why Operating Systems? -Modern computer system is very complex -OS manages all devices and provide user programs with simpler interface to the hardware

7. ²Main components of computer system -Hardware -Software -Application programs

8. ²WHAT IS AN OPERATING SYSTEM •  1. It is an extended machine • -Hides the messy details which must be performed • -Presents user with a virtual machine, easier to use • 2. It is a resource manager • -Each program gets time with the resource • -Each program gets space on the resource Program that acts as an intermediary between a user and the computer hardware

9. ²System components: -Process Management -Memory Management -I/O Management -File Management • Others: • Protection System, • Networking, • Command Interpreter

10. HISTORY OF OPERATING SYSTEMS First Generation (1945-1955): Vacuum Tubes and Plugboards -No programming language nor OS -Machine language -The use of plugboards, punched cards Second Generation (1955-1965): Transistor and Batch System -Introduction of transistor -Fortran, Assembler -Batch system

11. Second Generation (cont’d) -Offline system: -Operating System usually used: FMS (Fortran Monitor System) IBSYS (OS for IBM 7094)

12. Second Generation (cont’d) -Example of FMS job structure

13. Third Generation (1965-1980): ICs and Multiprogramming -IBM 360 for scientific calculation (i.e numerical) and commercial (i.e character-oriented) -IC (Integrated Circuit) -Introduction of multiprogramming

14. Third Generation (cont’d) • -Introduction of SPOOLING (Simultaneous Peripheral Operation On Line) • -Introduction of time-sharing • -Development of “computer utility” machine that supports hundreds of timesharing users • Eg: MULTICS (Multiplex Information and Computing Service) • --Development of UNIX (Uniplexed Information and Computing Service)

15. Fourth Generation (1980-now): LSI and PC • -LSI (Large Scale Integration) circuit and chips consisting of thousands of transistor  birth of PC (Personal Computer) • -User-friendly software • -Dominant Operating System: • MS-DOS, Win ME, Win NT • Unix, X Window • -Network Operating System • -Distributed Operating System

16. OS manages all devices and provide user programs with simpler interface to the hardware

17. Quis • Sebutkan alasan dan tujuan sistem operasi dibuat ! • Jelaskan dan gambarkan komponen sistem komputer ! • Jelaskan perbedaan off-line processing dengan spooling!
