What is Unix? Its History and Features

What is Unix? Its History and Features. Today almost all operating systems such as MacOS, Linux OS, Android are developed from the core of Unix. Unix is a type of operating system similar to DOS and Windows, although it is totally different and much more powerful. Unix was created several years before DOS and Windows, and it is also credited with the invention of DOS and Windows.

You’ve probably heard of the C-Programming Language. This language was created around 40-45 years ago. Despite this, it is now one of the most widely used programming languages.

C-Programming Language was specifically designed for the development of the UNIX Operating System.

In this article, I will tell you about What is Unix? Its History and features.

What is UNIX?

UNIX is an open source operating system or software. In which there are a large number of users and the ability to perform multiple tasks at the same time. It is known as a Multiuser and Multitasking Operating System for this reason. Bell Laboratories developed this operating system. Bell Labs is another name for the company.

It was created in 1969 by Ken Thompson, Dennis Ritchie, and his fellow computer scientists. However, the first version was launched in 1971. UNIX is the basis for practically all major operating systems today, including LinuxMac OS , Android, and iOS. Or, to put it another way, the UNIX Operating System is the mother of all operating systems.

The UNIX Operating System was originally written in Assembly and then rewritten in C. This is a different operating system that is faster, safer, more powerful, and more dependable than Windows. As a result, this operating system may be simply used even in limited areas. It’s also found in servers and workstations.

History of UNIX

Unix was created at AT&T Bell Laboratories in 1969. At this point, AT&T pulled its team from the Multics Project, and some of its members began working on a computing environment to continue programming research. Ken Thompson and Dennis Ritchie then planned and built a small two-user multitasking system.

All operating systems were created with a certain machine in mind, and computers were also constructed for a specific operating system and were always written in assembler.

Unix was rewritten in C, which was first written by Dennis Ritchie, in 1973, after it was originally written in assembler. Unix’s performance today is exceptionally fast, because to the fact that it was written in C. This made it easy to maintain and adapt to different hardware platforms. In fact, software that runs on Unix is substantially faster than software that runs on other operating systems, such as Windows NT.

What is the Feature of UNIX?

There are some feature is given below:

  1. The High Level Programming Language was used to create the UNIX Operating System. As a result, it is simple and easy to understand.
  2. Multi-user and multi-tasking are both possible with UNIX.
  3. Command Line Functionality is supported by the UNIX Operating System.
  4. The graphical user interface (GUI) is also seen in UNIX and Windows operating systems.
  5. Open Source License is offered for the UNIX Operating System.
  6. The UNIX Operating System is the mother of many popular operating systems.
  7. The UNIX OS  is written in a high-level programming language.
  8. The UNIX Operating System is also used in servers and supercomputers, in addition to smartphones and computers.
  9. UNIX is an operating system that is both fast and secure.

Architecture of UNIX Operating System

There are 4 layers in the architecture of Unix

  • Shell Commands
  • Application Layer
  • Hardware 
  • Kernel


In this article we have tried to give you complete information about UNIX. In which i will tell what is UNIX Operating Systemhistory of UNIX Operating System and what are the features of Unix. We hope you liked this information.
