History and Evolution of Operating Systems

In 1956, General Motors designed the 1st operating system and ran a Single IBM central computer. After that, there were tremendous changes and rapid evolution can be seen in the operating systems. Here is the timeline of the evolution of the OS

• 1st generation 1945-1955:- The 1st generation machines were programmed by individuals who knew the hardware intimately, in machine code.

• 2nd generation 1955-1965:- High-level languages like COBOL and FORTRAN invented, which made programming more portable and much easier as well.

• 3rd generation 1965-1980:- 3rd generation, integrated circuits make machines reliable and smaller, although they were very costly.

• 4th generation 1980 onwards:- 4th generation gave birth to the age of personal computers. 4th generation computers were used in very large integrated circuits.

• 5th generation 1980 to till now:- 5th generation is the birth of Artificial intelligence. It was the initiative of Japan’s Ministry of Trade and industry.

General-Purpose of Advanced OS

An advanced operating system is a very important software that works on a computer. It manages the memory and process of the computer along with its software and hardware. It also allows the user to communicate with the computer without knowing how to speak the computer’s language.

The three main purposes of an operating system are-

1. Manage computer resources such as CPU, printers, and disk drives.
2. Establish a user interface.
3. Execute and provide services for application software.

Kinds of OS

Embedded Operating Systems

• Serve a single application in a specific context
• Wireless access points, medical devices, washing machines, cars
• Small code footprint, real-time scheduling
• Might have virtual memory/process model
• Microkernels or single-address space: VxWorks, RTEMS, L4
• Now also: Linux, BSD over a real-time kernel
