Definizione di Unix

Unix is an operating system created by Ken Thompson and Dennis Ritchie in 1969. Initially planned to allow several programmers to use simultaneously the resources of a minicomputer, developed soon in a mainframe with the most disparate uses, in the universities as in the companies, becoming one of the best operating systems of always. Besides to be a multitasking and multi-user system, was written in a op-level language (the C language), and this made Unix the first portable operating system: it might be modified in order to work with the same features and capacity on various machines. In this way it was no longer necessary to redraft a whole software package every time a machine was becoming obsolete and ad to be changed with a new one.
