At least I've heard that many people know UNIX. UNIX is one of the oldest operating systems and is one of the most powerful operating systems available today. "According to today's standards, how UNIX is old and strong, the answer to this question is in the history of UNIX; UNIX is a subset of a larger, more complex operating system called MULTICS . UNIX and MULTICS were developed for large computers decades ago, but decades later, personal computers finally solve these multitasking, multiuser systems with advanced functions It was powerful enough to do. Returning to the first fact, Linux looks like UNIX. LINUX is not official UNIX, as it is not written by the same programmer on the original UNIX system. However, LINUX runs the UNIX program and shares the UNIX command set. For all common purposes and purposes, LINUX is a full-featured UNIX type operating system.

You may have heard about the operating system Unix, Ken Thompson, Dennis Ritchie, others developed in Bell Labs in the 1970s. Unix and Linux are similar in many respects, but in fact, the first created Linux is similar to Unix. Both have similar tools for connecting systems, programming tools, file system layout, and other major components. However, Unix is ​​not free. Over the years, various operating systems have been developed to try "unix-like" and "unix-compatible", but Linux has been the most successful and far more popular than its predecessor.

Most modern operating systems are affected by UNIX like UNIX. This includes Linux, macOS which are the closest to UNIX, except from UNIX. Because it is BSD and Mach, Windows hybrid kernel, and SUS-UNIX certified. Almost all operating systems you will encounter. The same can be said for small robots in set top boxes. It is mostly. But not all. For example, Windows is not generally considered a tradition of UNIX Windows NT borrows UNIX, but the Windows operating system borrows considerably the concept of UNIX promotion such as hierarchical file system and shell.
