What’s the point of UNIX?
UNI is a multiuser computer operating system. UNIX is widely used for Internet servers, workstations, and mainframe computers. UNIX was developed in the late 1960s by Bell Laboratories of AT&T Corporation due to efforts to create a time-sharing computer system.

What are the two types of special files in Linux?
In Linux, there are two types of special files: block special files and special drawing files.
What are the benefits of UNIX?
Benefits Full multitasking with secure memory. Very efficient virtual memory, so many programs can be run with a modest amount of physical memory. Access control and security. A comprehensive set of remote commands and utilities that do specific tasks well – not cluttered with many special options.
What is the heart of UNIX?
