Unix (pronounced yooniks) is a portable, multiuser and multitasking operating system, developed, in the last of 1960 and the early of 1970, by a small group of brain developers and programmers employed in the Bell Labs of AT&T.
Unix Development
Unix was created primarily with the C and Assembly programming language in order to be light and a flexible operating system, which makes it a portable system for the most platforms and computers where is installed the C compiler.
Unix Developers
Dennis Ritchie, Ken Thompson, Douglas McIlroy, Brian Kernighan and Joe Ossanna at the Bell Labs of AT&T.
Unix is a Open Source or a Closed Source Operating system?
Historically, Unix has a closed source, but there are some Unix projects like BSD family ( FreeBSD, OpenBSD, NetBSD, Darwin and PC-BSD) and Illumos that are open source operating systems.
Unix families
- AT&T is the pure and the original Unix family. Their most important operating systems are Unix System III and Unix System V.
- BSD: The invention of the TCP / IP protocols and its implementation on BSD gave rise to the Internet invention.
- AIX: it based on Unix System III for IBM.
- Xenix by Microsoft.
- GNU by Richard Stallman, it is a Open Source Project.
- Linux by Linus Torvals in 1991 when he developed the Linux Kernel and he collected collaborators and tools of the GNU project. Actually it is called GUN/Linux. Linux is considered in the Unix-Like familly operating systems, thus it is not a UNIX in the historical sense.
Unix Certification and Trademark
Just systems compatibles and certified by the Single UNIX Specification could be denominated by the "UNIX®" term. Others like Linux Operating System of Linus Torvalds are called Unix-Like. UNIX is a registered trademark of Novell, after a dispute with The Open Group in the United States and other countries
