What is the difference between unix and Linux?

Linux and Unix are both powerful operating systems and widely used server operating systems. There are many similarities, and some people even mistakenly think that Unix and Linux operating systems are the same. However, this is not the case. Here are the differences between them.

1. Open source

Linux is an open source operating system, which can be used for free. Unix is a traditional commercial software. Intellectual property protection of source code requires paid authorization.

2. Cross-platform

Linux operating system has good cross-platform performance and can run on various hardware platforms. The cross-platform performance of Unix operating system is weak, and most of them need to be used with hardware.

3. Visual interface

In addition to command line operation, Linux also has a form management system; Unix is just a system under the command line.

4. Hardware environment

Linux operating system has lower hardware requirements, and the installation method is easier to master. Unix has strict requirements on hardware and is difficult to follow.

5. User groups

Linux has a broad user base and can be used by both individuals and enterprises. Unix has a narrow user base, which is mostly used by banks, telecommunications departments and other large enterprises with high security requirements, or by Unix hardware manufacturers such as Sun.

Compared with Unix operating system, Linux operating system is more popular with computer enthusiasts. Mainly because Linux operating system has all the functions of Unix operating system, it can realize all the characteristics of Unix on ordinary PC, and it is open source and free, so it is easier to popularize!
