In 1969 a team led by computer scientists Ken Thompson and Dennis Ritchie created the first version of UNIX on a PDP-7 minicomputer, which was chosen mainly because of Thompson’s familiarity with the system from his hobby work on it. Thompson left Bell Laboratories for a while and taught a course on UNIX at the University of California at Berkeley in the mid-1970s. A shell is a medium provided to interact with the kernel which is a Command Line Interface (CLI) to the Unix system. No other operating system can make this possible. Experience, The source code of Linux is freely available to its users, The source code of Unix is not freely available general public, It has graphical user interface along with command line interface, Linux OS is portable, flexible, and can be executed in different hard drives. It was developed in the 1970s by Ken Thompson, Dennis Ritchie, and others in the AT&T Laboratories. The Unix operating system is a set of programs that act as a link between the computer and the user. The main features of UNIX—its portability (the ability to run on many different systems), multitasking and multiuser capabilities, and its extensive library of software—make it as relevant and useful today as it was in 1969. Corrections? Difference between Unix and Linux – Multiple users can run multiple programs each at the same time without interfering with each other or crashing the system. It's free . It was originally meant for programmers developing software rather than non-programmers. It was developed in the 1970s by Ken Thompson, Dennis Ritchie, and others in the AT&T Laboratories. Information and Resource Protecti⦠Every computer requires an operating system. Unix started life at AT&T's Bell Labs research center in the early 1970s, running on DEC minicomputers.By 1976, the operating system was in use at various academic institutions, including Princeton, where Tom Lyon and others ported it to the S/370, to run as a guest OS under VM/370. UNIX Shell is a collection of computer operating systems that allow multiple users to do multiple tasks. Advantages and disadvantages of Unix . Students and professors there further enhanced UNIX, eventually creating a version of UNIX called Berkeley Software Distribution (BSD). Surely you are wondering what advantages UNIX can offer compared to modern systems today. This would be the first of many ports of UNIX.
