What is the server used for? What is its specific function?

As we all know, the computer room is an important resource for server hosting providers. To choose a reliable server hosting provider, you must inspect and visit IDC's computer room. Today, let's learn about the necessary server guarantee requirements for the computer room, so that everyone can choose the computer room.Server rack cabinet During the inspection, know what are the key points of the computer room.

The server is defined as follows:

The server is a high-performance computer. As a node of the network, it stores and processes 80% of the data and information on the network.rack 42u Therefore, it is also called the soul of the network.

It can also be said that a server refers to a computer software that manages resources and provides services to users. It is usually divided into file servers, database servers and application servers.server rack server The computer or computer system running the above software is also called a server.

Compared with ordinary PCs, servers have higher requirements in terms of stability, security, performance, etc. Therefore, hardware such as CPU, chipset, memory, disk system, and network are different from ordinary computers in terms of quality and processor data. Better performance.

The functions of servers and computers are the same. We can also call servers computers, but servers have higher requirements for stability, security, and processor data capabilities.

Servers have a wide range of functions. Online games, websites, and some software all need to be stored on the server. Some companies also provide servers, and their important work information is stored on the hard drive of the server.

The role of the server is as follows:

As a node of the network, the server stores and processes 80% of the data and information on the network, so it is also called the soul of the network.

To make a vivid metaphor: the server is like a switch in the post office, and fixed or mobile network terminals such as computers, laptops, PDAs, and mobile phones are like telephones scattered in homes, various offices, public places, etc.

Our daily life and work telephone exchanges with the outside world must go through a switch to reach the target phone number; the same is true for network terminal equipment such as microcomputers in homes and businesses to access the Internet to obtain information, communicate with the outside world, entertain, etc. It must go through the server, so it can also be said that the server "organizes" and "leads" these devices.

It is a high-availability computer that provides various services to client computers on the network. Under the control of the network operating system, it provides the hard disk, tape, printer, Modem and various special communication equipment connected to it to the network. Customer site sharing can also provide network users with services such as centralized computing, information publishing, and data management.

Its high performance is mainly reflected in high-speed computing capabilities, long-term reliable operation, and powerful external data throughput capabilities.
