This article mainly introduces what it means that the website in the computer is not connected to the server. What is introduced in this article is very detailed and has a certain reference value. Interested friends must finish reading it!

The site is not connected to the server is not connected to the relevant server can not log in, or the other party's server is not open. Server is a kind of computer, which runs faster, has a higher load and is more expensive than ordinary computers.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

Not connected to the server is not connected to the relevant server, can not log in. Or the other party's server is not turned on. Server is a kind of computer, which runs faster, has a higher load and is more expensive than ordinary computers. The server provides computing or application services for other clients (such as PCs, smartphones, ATM terminals and even large devices such as train systems) in the network.

The server has high-speed CPU computing ability, long-time reliable operation, strong external data throughput and better expansibility. According to the services provided by the server, generally speaking, the server has the ability to respond to service requests, undertake services, and guarantee services.

Extended data:

If you look at servers from different angles, you can classify servers in different ways. Let's discuss the classification of servers from different angles.

1. According to the architecture, servers can be divided into two important categories: IA architecture servers and RISC architecture servers.

This classification standard is mainly based on the different processor architectures adopted by the two servers. The CPU used by the RISC server is the processor of the so-called reduced instruction set. The main feature of the reduced instruction set CPU is that it uses fixed-length instructions and pipelined to execute instructions. The processing of such an instruction can be divided into several stages. The processor sets different processing units to execute different stages of instructions. For example, if instruction processing is divided into three stages, when the N instruction is in the third processing stage. The N + 1 instruction will be in the second processing stage, and the N + 2 instruction will be in the first processing stage.

This pipelined processing of instructions makes CPU have the ability to process instructions in parallel, which enables the processor to process more instructions per unit time. The server of IA architecture adopts CISC architecture, that is, complex instruction set architecture, which is characterized by longer instructions, stronger functions of instructions and more functions that can be executed by a single instruction, so that we can improve the computing power by adding computing units so that the functions executed by an instruction can be executed at the same time.

For a long time, the two architectures have been growing in competition with each other, and have made rapid development. The server of IA architecture adopts open architecture, so it has a large number of hardware and software supporters, and has made great progress in recent years.

2. According to the scale of the server, the server can be divided into workgroup server, department server and enterprise server.

This classification method is a relatively old classification method, which is mainly classified according to the scale of the server application environment. For example, a computer network environment with about ten clients is suitable for using a workgroup server. This kind of server often uses one processor, small hard disk capacity and not very strong network throughput. A computer network with dozens of clients is suitable for departmental servers, and departmental servers have relatively strong capabilities, often using 2 processors, large memory and disk capacity, and strong capabilities of disk ID O and network ID O, so that this server can have sufficient processing power to accept the service requirements put forward by the client.

In order to undertake the response to a large number of service requests, this kind of server often uses 4 processors, has a large amount of hard disk and memory, and can be further expanded to meet higher requirements. At the same time, in order to cope with a large number of visits, the network speed and disk speed of this kind of server should also be very high.

In order to meet this requirement, it is often necessary to use multiple network cards and multiple hard drives to process in parallel. All the above descriptions are very imprecise, and there are many special cases, for example, there may be many clients in a network, but there may be very little access to the server, so there is no need for an enterprise server with super function. because of these factors, the classification of this kind of server tends to be qualitative rather than quantitative, that is to say, from the group level to the departmental level to the enterprise level. The performance of the server is gradually enhanced, as are other features.

3. We can divide servers into many categories according to their different functions.

For example, the file / print server, which is the earliest type of server, can perform file storage and printer resource sharing services. up to now, this kind of server has been widely used in office environment. Database server, which runs a database system, is used to store and manipulate data and provide data query and modification services to networked users. This kind of server is also a kind of server widely used in commercial systems.

WEB server, E-MAIL server, NEWS server, PROXY server, these servers are typical INTERNET applications, they can complete the home page storage and transmission, e-mail service, newsgroup service and so on. All these servers mentioned above are not just a hardware system, they often achieve their specific functions through the combination of hardware and software.
