Unix is an operating system that appeared in the early 1970s and can be used as a stand-alone operating system in addition to a network operating system. Unix, as a development platform and desktop operating system, has been widely used in engineering applications and scientific computing.

What is the difference between Linux and Unix?

1. Unix systems are mostly hardware-compatible, that is, most Unix systems such as AIX and HP-UX cannot be installed on X86 servers and PCS. Linux, on the other hand, runs on multiple hardware platforms.

Unix is commercial software, while Linux is open source software, which is free and open source.

Unix is a command line system, Linux is a Windows management system.

4. In terms of hardware requirements, Linux is lower and less demanding than Unix and easier to install than Unix.

Why is Linux so popular? Here’s why:

1. It is open source software. Users can obtain it and its source code without paying fees, and can make necessary modifications to it according to their own needs, use it for free and continue to spread without restriction.

2. It has all the functions of Unix, and anyone who uses or wants to learn Unix can benefit from Unix.
