Linux and Unix belong to the same operating system, and many people know that there are many similarities between them, so people are a little fuzzy when choosing, so how to distinguish between Linux and Unix? Let's take a look.
What is Unix?
Unix was developed by AT&T in New Jersey in 1969. Many operating systems were inspired by Unix, and Unix was also inspired by the unfinished Multics system. Another version of Unix is Plan 9 from Bell Labs.
Unix is mainly used in servers and workstations, and may also be used on personal computers. It plays an important role in the Internet, computer networks, client and server models.
The main features of Unix: support multitasking, simpler operation than Multics, data storage in plain text, and simultaneous access to multiple user accounts.
What is Linux?
Linux is an open source operating system based on the Unix operating system and a freely downloadable system. Linux is different from other systems, other systems need to be paid, and Linux is also established as a commercial system.
Linux is a free-to-use and freely disseminated Unix-like operating system. It is a multi-user, multi-tasking, multi-thread and multi-CPU operating system based on POSIX and Unix. It can run major Unix tools, applications, and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits Unix's network-centric design philosophy and is a multi-user network operating system with stable performance.
Linux main features: multitasking, support for multiple threads, multiple users, personal accounts are protected by appropriate authorization, etc.
