UNIX

UNIX is a powerful computer operating system that was developed by AT&T Bell Laboratories in 1969. The UNIX operating system can be utilized on various platforms, running a larger assortment of hardware than on many other operating systems. UNIX has become the operating system of choice for workstation computers directly linked to networks rather than on operating systems for personal, desktop or individual PCs. The UNIX operating system is predominantly used by mid-sized businesses and universities.

The UNIX operating system is experiencing an expansion in development from the viewpoint of technical professionals. Although UNIX is used mainly for large institutions, it is becoming more popular amongst IT professionals as the operating system of choice and has recently been installed as the native operating system on some notebooks and laptops for personal use. The majority of UNIX operating systems is related to scientific and engineering workstations and used on many Internet service providers’ servers. UNIX contains a modular construction, allowing it to be modified in a simple and efficient manner.

The tutorials in this section will help programmers and developers to fully understand the functionality, benefits and intricacies of the UNIX operating system. Helpful e-books, quick reference guides and practice configuration of code are available in easy to use tutorials.
