What is the origin and understanding of linux, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

Understanding of the operating system:

Today we start the origin of linux. Before we start, let's talk about linux. Now we say that Linux is something that users thought was very high-end before at least 2008, because only servers, hackers and foreign users used it more.

Today, we say linux is more appropriate, because in the 5G era, everyone has a mobile phone (andriod operating system, that is, a linux-like operating system), so Linux has become very common to us ordinary people. The reason for this unfamiliarity is mainly because the Chinese used Microsoft's windows operating system at the beginning, but the rise of domestic linux also brought a lot of surprises to the Chinese open source operating system, such as:

Huawei's Hongmeng system; deep deepin linux; red flag linux and so on.

The evolution of the operating system: (we won't tell it according to history)

Now our story: computer (hardware), operating system.

X86 architecture, ARM architecture, and so on. In the beginning, the operating system was not used in x86 architecture (ordinary people's computers).

Phase 1:

The United States began to be informationized, especially in the economic competition with Russia during the Cold War, and the United States began to connect the Internet in the information military (this is the embryonic form of the Internet). It was a good year in 1984.

Nodes running on the network: routers, node computers. 1984 cisco (the Internet giant) came out of the router; computers use giant devices and run the unix operating system.

Phase 2:

Information, from military to civilian, the first is the use of universities, the Internet began a variety of protocols are not unified, resulting in enterprises have their own operating system, network communication protocols. It makes unified communications difficult unless you all use the same company's products. Of course, the IEEE organization designated the OSI 7-layer model, gradually moving towards the unified direction of the Internet.

Why 1984 is a good year linux appeared; TCP/IP appeared (a network protocol standard that is more suitable for practical use than the OSI 7-layer model), so 1984 can be said to be the first time for the Internet to take off.

At this time, the operating system, that is, large computing devices, still need to apply in advance and queue up. After all, there are too few devices, which are not as common as today's devices. The operating system used is UNIX.

Stage 3:

When you get back on track, you can see the evolution of operating system OS by looking at the picture.

Unix (multi-user system For large equipment) |-| BSD linux unix- -| |-unix macOS DOS | windows | | | | FreeBSD ubuntu redhat SUSE Red Flag .etc | Android

Finally:

Do you think your daily windows is so close to the linux system? It's all the same origin, but the windows interface is better encapsulated. When many people get used to it, they think that windows is good, linux is not easy to use.

Secondly, they are actually a family, but the orientation is different. Linux generally does not use a graphical interface (for servers); windows desktops do better and are generally used for ordinary users. At the beginning of the next article, we use to communicate how to choose the Linux that suits us.
