History of Operating System

Development of the operating system itself heavily influenced the development of hardware.Berikut the Operating System that is classified according generasinya:

1. Generation to Zero (1940)

A. Main component is a vacuum bottle (vacuum tube)
B. Not use the computer Operating System
C. All computer operations performed manually through the manual plugsboards, and can only be used to calculate.

2. First generation (1950)

A. Its main components form trasistor
B. Operating System to function as a regulator, especially between the job turnover at the time of installation so that the next job more efisien.Dalam this generation, showing what is called a batch system (all similar types of jobs are collected into one)
C. Using punch card input

3. Second Generation (1960)

A. The main components such as IC
B. Develop basic concepts:

- Multiprogramming, a process the many processes in the memory.
- Multiprocessing, a job done by a lot of processor, which is to improve the utility
- Spooling: (simultaneous Peripheral Operation On Line). Beringdak as a buffer only, and is able to receive orders even if not yet done akan.
- Device Independence, each component has a different nature of each other (eg, each printer has a different driver)
- Time sharing or Multitasking
- Real Time System.berguna as a control for the engine

4. Third Generation (1970)

A. The main components VLSI (Very Large Scale Integration Circuit)
B. Marked berkambangnya with the concept of general purpose system, so that the operating system becomes very komples, expensive and difficult to learn.

5. Fourth generation (1970 - until now an)

A. PC increasingly popular
B. Marked with the development of operating system for computer network for the purpose of data sharing, program sharing and hardware sharing
C. User interface more user friendly
