Where Did UNIX Come From and Why Are There Different Versions Of UNIX? The first efforts at developing a multi-user‚ multi-tasking operating system were begun in the 1960’s in a development project called MULTICS. While working for Bell Telephone Laboratories in 1969 and 1970‚ Ken Thompson and Dennis Ritchie began to develop their own single-user‚ multi-tasking small operating system and they chose the name UNIX. Their initial goal was simply to operate their DEC PDP machines more effectively.

: Linux and Unix Unix is popular operating system‚ developed by AT&T in 1969 and it has been very important to the development of the Internet. It is a multi-processing‚ multi-user‚ family of operating systems that run on a variety of architechtures. UNIX allows more than one user to access a computer system at the same time. A widely used Open Source Unix-like operating system kernel. Linux was first released by its inventor Linus Torvalds in 1991. Combining the Linux kernel with the GNU software

Unix File Protections ABSTRACT Unix is a multifunctional platform capable of handling several users accessing the same applications and files at once. It accomplishes this by setting up a permissions hierarchy and assigning users into groups. As multifunctional as it is‚ several problems still exist. For one‚ it has a command line interface. There is no graphical user interface. Second‚ privilege changes are made either one by one or all at once. Anything else would need

Some Basic UNIX Commands NB*”Rm” The UNIX operating system has for many years formed the backbone of the Internet‚ especially for large servers and most major university campuses. However‚ a free version of UNIX called Linux has been making significant gains against Macintosh and the Microsoft Windows 95/98/NT environments‚ so often associated with personal computers. Developed by a number of volunteers on the Internet such as the Linux group and the GNU project‚ much of the open-source software

Windows NT vs Unix As An Operating System In the late 1960s a combined project between researchers at MIT‚ Bell Labs and General Electric led to the design of a third generation of computer operating system known as MULTICS (MULTiplexed Information and Computing Service). It was envisaged as a computer utility‚ a machine that would support hundreds of simultaneous timesharing users. They envisaged one huge machine providing computing power for everyone in Boston. The idea that machines as powerful

Xenix- a discontinued Unix operating system What is Xenix? Xenix is an operating system‚ which supports a computer’s basic functions. It is a discontinued version of Unix‚ a set of operating systems. Xenix was created by Bell Labs‚ which was part of the Bell System‚ and was owned by AT&T. Due to an antitrust case‚ which aimed to prevent AT&T from gaining control of the market‚ they were initially forbidden from entering the computer market. This meant that they were unable to sell Unix directly to customers
