UNIX...simply put, is a robust and scalable operating that has been in existence for almost over 30 years. In some cases, it ***** been called "the gr*****father of ***** systems" as a result ***** the ***** it h*****s been extant. The OS was developed in the 1960s and born out of ***** need by Bell Laboratories in the United States to have an operating system that could be use by its staff to assist *****m in their scientific ***** academic research. It is older than Microsoft's brand of operat*****g systems and considered more secure and less bug/error-free! "***** was designed for users who were largely com*****er scientists and AT&T (the owners ***** Bell *****) made UNIX available at nominal cost to academic *****, with whom it became popular. This helped to cre*****e a market for *****, at a time when technologic*****l changes had themselves created a need for ***** portable multi-user operating system. As a result UNIX began to be adopted ***** non-academic users in the 1980's as it became commercially available. Several st*****ards are now being worked out, and UNIX is steadily becoming ***** st*****ard operating system in many environments. (Wynne, 1997)"

***** is still in used by millions of server worldwide and despite various variants ***** over the years, the b*****ic kernel remains ***** same with variations made depending on the needs of an individual or organization. A more popular offshoot - although Linus Torvalds at times won't admit it ***** is the Linux family of operating *****. "The ***** for the UNIX system continues to expand. IDC estimates the market at US$ 39 billion in 1996 and forecasts the market ***** be US$ 50 billion in the year 2000. In addition, the installed base of the UNIX ***** has an estim*****ed value of *****$ 122 *****. These market estimates lead to several conclusions about the UNIX system, as follows: An annual market of US$ 39 billion ***** large enough to remain attractive to ***** suppliers ***** ***** provide sufficient revenue to fund continuing high levels ***** investment in support and product enhancement. The UNIX *****'s growth rates, which appear modest in comparison ***** ***** unit shipment growth of newer products, are anchored by an enormous ***** base. High unit shipment growth ***** are typical of new entries in a m*****rketplace. (UNIX Systems Cooperative Promotion Group, 2006)"

One of the main reasons for UNIX's unparalleled use and steady market growth is its portability, multi-*****r and multi-tasking ability especially ***** it comes to deployment in *****s and workstations. In ***** client-server architecture, UNIX was *****strumental in the development of ***** Internet as well as networking environment for ***** types ***** computers whether mainframe, microcomputers or PCs. The basic property of the UNIX ***** is the ***** which sources out ***** commands ***** the whole system from booting, execution ***** shutdown. "***** kernel is the part carries out basic operating system functions such as accessing files, allocating mem*****y and handling communications. A shell provides
