Get to know Linux: a free, stable and high-performance operating system

Regarding Linux, its basic concepts should be familiar to you. The official definition: Linux is a set of Unix-like operating systems that are free to use and freely disseminated. It is a multi-user, multi-task, multi-threading and multi-CPU operating system based on POSIX and UNIX. It can run major UNIX software tools, applications and network contracts. It supports 32-bit and 64-bit hardware. Linux inherits the network-centric design philosophy of Unix and is a multi-user network operating system with stable performance.

Why use Linux? What is the value of Linux?

The main advantages of Linux are stability, freeness and good performance.

Stability, where is it demonstrated? We use PCs, not only in some special circumstances. If you use Linux, you can usually last for a month without restarting. If the operating system is Windows

Free, you should be aware of this. The Windows operating system is not free. For Internet companies, it is terrible to pay Windows protection fees. In comparison, using free Linux is a good choice.

In terms of performance, Linux has done a lot of optimizations. For example, Linux will cache the file directories and file contents of free video memory. If virtual video memory is not needed, it will not be used. However, Windows will definitely use virtual video memory, although the video memory is sufficient.

In terms of software, Linux has huge open source software support, web servers, cache servers, database servers Check out the linux 64-bit system , those are free options and are stable and mature products.

But I think Linux seems to be really strong in the server field, but there are also certain shortcomings in the Linux operating system interface. On personal laptops, the graphical interface is not friendly enough, but there is no specific manufacturer support, while Windows has good users experience.
