Objectives of UNIX. UNIX was designed with the following goals in mind: creating an interactive system designed by programmers and programmers shared time, intended for qualified users. as simple, elegant, concise and consistent. that would allow solving complex problems by combining a small number of basic commands. Philosophy of the UNIX system. Objectives was created with that determined a UNIX philosophy characterized by: short, simple, specific and very efficient, commands that do one thing but do it very well. standardized input and output that allow the interconnection of commands. This is called casing (pipelining): the output of a command is taken by the following as input. The modern UNIX. In first instance oriented character terminals, currently available graphical interface x-Windows. This has greatly simplified the use for non-specialists. It is ideal for working as a server: a powerful as personal computers, terminals or server machine cheap in jobs. Free use Samba package allows a UNIX machine to act as a server for Windows 3.11, Windows 95, and Windows NT jobs. It is oriented in the opposite direction to the trend of making invisible to the operating system user, allowing the use of all libraries, calls to the system and internal tools, although its use requires a high level of specialization. It is possible to compile a kernel specifically adapted to the particular needs of a company or group of work, reducing the use of resources and increasing the speed. The RISC of 1980s and 1990s machines adopted UNIX as the operating system; It is by far the predominant system in calculations and research-oriented workstations. It was also adopted for the creation of the Internet, mostly supported by UNIX. By its design features, it is specially prepared for its expansion and development in 64-bit and multiprocessing in multiple CPUs. Original author and source of the article.
