Let's talk about the differences between Linux and Unix.

I would like to share some of the following with you. I love programming and hope to be more programmers. If you are one of them, please add your friends, the following articles are useful things for you. You can take notes for yourself and hope to help you. Thank you for reading them first ~!

The core of linux is free and free to use. The core source code is open. The core of unix is not open.

In terms of hardware, linux is lower than unix and less demanding than unix. linux is easier to master than unix in installation.

Linux is not as complex as unix.

Most Unix systems are the operating systems of hardware vendors targeting their own hardware platforms. They are mainly related to CPU and so on. For example, Sun Solaris is commercially used, it is located on the workstations and servers that use the CPU Of the instance. Of course, Solaris also has the x86 version, while Linux also has the server version of the CPU of the instance. But to be exact, it is not appropriate to take the Unix on the RISC and the Linux on the x86. As for the price, the Linux used by individuals is basically free of charge. Different Linux vendors have some optimizations for Enterprise-level applications on basic systems, such as RedHat Enterprise Products, these products, including support services, are expensive. For Unix systems like IBM/HP/SUN, the operating system is usually priced at the device price because it is mainly targeted at its hardware platform. (No one buys a Unix operating system separately ).

In terms of performance, linux is not as comprehensive as unix, but it is more than enough for individual users and small applications. Generally, if you have the opportunity to use Unix environments, such as the banking and telecommunications departments, they are generally fixed-type Unix. For example, SUN in China Telecom, HP in civil aviation, and IBM in banks. Note that different Unix Command sets are different in learning.

As for the study, I think linux is a little more studious, and now there are more and more people who like and encourage linux, and there are also a lot of information about linux. if you want to learn it yourself, Linux or BSD is a good choice. One x86 machine is enough. For applications, unless they are large websites, enterprises or individuals can simply use Linux.

UNIX is a powerful multi-user, multi-task operating system with comprehensive performance. It can be used on a variety of platforms from a giant computer to a general PC. It is the most widely used and influential operating system.

Linux is an operating system with the same appearance and performance as UNIX. However, Linux does not come from any version of UNIX source code, but is similar to UNIX. Linux successfully imitates UNIX systems and functions. Specifically, Linux is an operating System compatible with System V and bsd unix. For System V, currently, the software program source code can be run after being re-compiled under Linux. For bsd unix, its executable files can be run directly in Linux.

Generally speaking, Linux is an operating system that complies with POSIX (Portable Operating System Environment) specifications. It can implement all UNIX features on general PC computers and has the capability of multi-task and multi-user. Another major reason Linux is favored by many computer enthusiasts is that it has all UNIX functions, and anyone who uses a UNIX operating system or wants to learn a UNIX operating system can benefit from Linux.

In terms of network management capabilities and security, people who have used Linux admit that Linux is similar to UNIX. UNIX systems have been used as high-end applications or server systems. Therefore, they have a complete set of network management mechanisms and rules. Linux follows these excellent rules to make the network highly configurable, it provides great flexibility for system management.

We can acquire real knowledge through continuous learning, never satisfy the current knowledge, and keep forging ahead is fundamental. This is also true in the world of programming, I like to get new knowledge. I hope you will be the same, and there is no end to learning!
