What is a server? What is the role of servers in the Internet?

In fact, the server can also be regarded as a computer. It is not a complicated thing. Because I am doing server operation and maintenance, I perform some operations on the server every day. Operating the server is actually similar to our normal operation of the computer. .

The only difference is that the server is operated remotely,Server rack cabinet while our computer is actually operated in a running environment where the server usually deploys some applications, just like the web pages we often browse require server support.

When programmers first entered the Internet industry, in order to save the cost of learning, we all deployed our own computers as servers. However, the servers deployed with our own computers could only be accessed locally.rack 42u If we wanted to access them through the public network, It is still relatively complicated, but there are also some third-party platforms that have already made relevant deployments and only need to be parsed.

What I want to express by saying so much is that the server is just like our computer,server rack server it just deploys the running environment of some applications and we can access it on the public network.

Many applications in the mobile phones we use in life are related to the server. For example, when we use WeChat to chat, when we enter the content and click send, it will connect to the server, and then receive This content will be sent to the users who need to receive it later on WeChat. If there is no intermediate link, the content we send will not be received by the other party.

Maybe this explanation is not very clear to some people. Let’s use the game Contra that we often played when we were children as an example. When we played at that time, we used the TV to connect to our game console. When friends play together, they can only sit together and play. Game console A cannot play with game console B.

But this goal can be achieved through the server. Even if two people playing the game together are far apart, they can complete the level together.

The above is actually the role of servers in the Internet. Of course, this is only a very one-sided explanation, but for people who are not engaged in related industries, it is enough to understand this step.

More research needs to be done on it, which is done by very professional people. For example, some companies have the position of operation and maintenance. Operation and maintenance is a position that professionally maintains servers. What is applied here There is more knowledge, and a certain amount of professional knowledge is required to understand all aspects from the organization of the equipment to the operating environment and system code.

Servers mainly store mostly websites. The three major components used in websites are servers, domain names, and website codes.

When we browse a web page, the browser will first make a request to the server pointed to by the domain name. After receiving the request, it will execute the website code and return the corresponding content. Then the browser will interpret the returned content into something we can understand. text information.

The role of servers in the Internet is still very important, and different performances also have certain differences in price. Generally, websites with more traffic have higher performance requirements.
