This article mainly explains "what the server is for". The content of the explanation in the article is simple and clear, and it is easy to learn and understand. let's follow the editor's train of thought to study and learn "what is the server for?"

When it comes to the name server, many people will remember it. However, when it comes to the specific use of the server, everyone said that it is not clear. The following editor will introduce to you what the server is for?

What is a server:

Server, also known as server. The server is a high-performance computer in the network environment, which listens to the service requests submitted by other computers (clients) on the network and provides corresponding services. for this reason, the server must have the ability to undertake and guarantee the service. Sometimes, these two definitions can cause confusion, such as the Web server for domain name registration queries. It is usually divided into file server (which enables users to access files on other computers), database server and application server.

A server is a computer system that manages and transmits information.

The server is a kind of high-performance computer, as the node of the network, it stores and processes 80% of the data and information on the network, so it is also called the soul of the network. Make a visual analogy: the server is like a post office switch, while fixed or mobile network terminals such as microcomputers, notebooks, PDA, mobile phones, such as telephones scattered in homes, various offices, public places, and so on. In our daily life and work, telephone communication and communication with the outside world must go through the exchange before we can reach the target telephone. similarly, network terminal devices, such as microcomputers in homes and enterprises, surf the Internet and obtain information. Communication and entertainment with the outside world must also go through the server, so it can also be said that the server is "organizing" and "leading" these devices.

It is a kind of high-performance computer on the network that provides various services for client computers. Under the control of the network operating system, it provides the connected hard disk, tape, printer, Modem and all kinds of special communication equipment to the customer sites on the network to share. It can also provide network users with centralized computing, information publication and data management services. Its high performance is mainly reflected in high-speed computing power, long-term reliable operation, strong external data throughput and so on.

The composition of the server is basically similar to that of the microcomputer, including processor, hard disk, memory, system bus and so on, which are specially designed for specific network applications. therefore, there are great differences between servers and microcomputers in terms of processing capacity, stability, reliability, security, scalability, manageability and so on. Especially with the progress of information technology, the role of the network is becoming more and more obvious, and the requirements for the data processing ability and security of your information system are getting higher and higher. if you are stolen by a hacker in the process of e-commerce, key business data will be lost If you cannot access the ATM properly, you should consider the behind-the-scenes commander of these equipment systems-the server, rather than complaining about the quality of the staff and other objective conditions.

At present, according to the architecture, servers are mainly divided into two categories: ISC (reduced instruction set) architecture servers: these are servers that use RISC chips and mainly use UNIX operating systems, such as SPARC of Sun, PA-RISC of HP, Alpha of DEC, MIPS of SGI and so on.

IA architecture server: also known as CISC (complex instruction set) architecture server, that is, PC server, which is based on PC architecture and uses Intel or compatible processor chips, such as Lenovo's Wanquan series, HP's Netserver series servers and so on.

Thank you for your reading. the above is the content of "what is the server for?" after the study of this article, I believe you have a deeper understanding of what the server is used for. The specific use of the situation also needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
