all operating systems which are registered with the “Unix” name because they comply with the aforementioned standards.The certification is not free, and requires the developers of an operating system to pay trademark royalties for the name. Only those operating systems which comply with the standards can legally bear the name “Unix”. the trademark – written in all caps, UNIX – held by The Open Group, which also developed a set of standards for operating systems called Single Unix Specification.the original operating system developed by AT&T Bell Labs from which other operating systems derive.The term “Unix” can refer to the following: However, today it runs on more platforms than any other OS, including servers, embedded systems and mobile phones. Unlike Unix, which was used on servers, large mainframes and expensive computers at various institutions, Linux was developed for personal computers, a much simpler type of hardware.

The design of the Linux kernel was influenced by MINIX, a variant of Unix, but the entire code was written from scratch, not borrowed from it. Since their own kernel was incomplete, the GNU Project accepted the Linux kernel, and so the operating system GNU/Linux was born.

The goal of the GNU Project was to create an operating system similar to Unix, but separate from it in other words, containing no code from Unix so that it could be further modified and distributed without limitations as free software. As an operating system, it grew out of two projects: the GNU Project, started by Richard Stallman in 1983, and the Linux kernel, written by Linus Torvalds in 1991. Linux is based on Unix in spirit and functionality, but not in code.

Soon, derivatives and variants of Unix for different purposes and with different licenses started popping up, with BSD (Berkeley Software Distribution) as probably the best-known among them. This meant that not everyone could freely modify and distribute the source code, essentially making Unix a proprietary operating system. This made it much easier for developers to port Unix to different computing platforms.Īs the development of Unix continued, AT&T started selling licenses for its usage to universities, and later to commercial vendors. In 1970 the new product was given the name Unix, and two years later its code was entirely rewritten in the C programming language. Some of their researchers were unhappy with the progress of the project, and withdrew to create their own OS. Together with MIT and General Electric, the Bell Labs were developing a new operating system.
The story of Unix began in the late 1960s and early 1970s, in the computing research department of AT&T Bell Labs in the United States. As always, you’re welcome to ask questions and add more information in the comments.
In this article we bring you a simplified story of Linux and Unix to help you understand their relationship. Generally, it depends on how you interpret each of these two terms, because both can have different (yet related) meanings.
