The difference between linux and unix

UNIX is a multi-user and multi-task operating system with powerful functions and comprehensive performance. It can be applied on a variety of different platforms from supercomputers to ordinary PCs. It is the most widely used operating system. The most widespread and influential operating system. (Recommended learning: linux operation and maintenance)

Linux is an operating system with the same appearance and performance as UNIX or better, but Linux does not originate from the source code of any version of UNIX. It is not UNIX, but a product similar to UNIX.

Difference:

Linux is free software that develops source code, while UNIX is traditional commercial software that implements intellectual property protection for source code.

Most UNIX systems are matched with hardware, while Linux can run on a variety of hardware platforms.

UNIX is a system under the command line, and Linux is a system with form management.

In terms of hardware requirements, Linux is lower than Unix and not as demanding as Unix. Linux is easier to master than unix in terms of installation.

Additional:

1. There are currently three mainstream Unix systems, namely AIX, HP-UX, and Solaris. They run on their own Unix servers. These Unix servers are self-contained and have their own CPUs, memory, motherboards, etc.

2. These Unix systems are incompatible with each other. They each have their own system engineers. These engineers are generally only familiar with certain Unix systems. If you want to be familiar with other Unix systems, you have to continue to learn these. Unix systems are not good or bad, only different.

3. In addition, Unix servers are currently used in key application fields in various industries. Why? Linux generally runs on PCs, is not very stable, and has insufficient parallelism. It is generally used in small businesses.

4. The Unix system runs on Unix servers. These servers are very stable and have experienced decades of testing. The number of CPUs in these Unix servers can reach more than one hundred. The degree of parallelism is very high, which is unmatched by PCs.

5. Currently, Unix servers are in a monopoly position in key applications in telecommunications, finance, oil fields, mobile, securities and other industries. Therefore, only by mastering Unix can you truly enter the high-end industry, which is crucial for future career development.
