Client-Server Architecture

Client-server architecture is the organizational construction of a local or distributed network, in which there is a separate server and electronic nodes (client), between which the computing network load is shared, which ensures their joint work. Very often, the interaction in the network based on the server and the client is carried out through a network of computers. Also, the server and the client can be not only electronic devices, but also software or an application.

LAN with dedicated server

The client-server architecture can mean a structure in which the client is several (usually about ten)   Computers, for which a separate central electronic node-server is allocated. Such a group of electronic devices is called a "local network with a dedicated server".

The network administrator has unlimited rights to change the configuration of the server. It has the ability to install any operating system, as well as the maintenance of the central node. The basic information database can reside on both the server computer and (for security purposes) on any other electronic device that is part of the network. The location of the database outside the web server is also very convenient because it ensures the continuity and consistency of all network computers during the technical work of the central web machine.

A network with a dedicated server is usually used to ensure uninterrupted data exchange between branches of a large organization or enterprise. Another use of such an architecture takes place in networked computer games. Thus, continuous 24-hour access to the playground from the network is provided.

Client - computing program

Under the concept of "client-server architecture" often mean also the distribution of network load between the client and the server, where the client is a computing program. In this case, all confidential data is located in the central information database on a powerful server computer. Monitoring and protection of information is also provided by the server node. This organizational structure is very advantageous in that it is much better and more reliable on the server to protect confidential data from unauthorized attempts to gain access to them. On the server, access control is established, as a result of which, information is only opened to users with specific credentials.

Principles of the architecture of the client-server architecture

Client-server architecture can be built on the principle:

1. A dual connection, providing one web server and about ten clients.

2. A triple connection in the structure of which there is an intermediate link (a Web site) located between the server and the client. This link serves as an intermediary in the processing of requests and received data, or to ensure protection of access to information, as well as protecting it from damage and destruction. In this case, the number of workers or gaming places on the network can be much increased.

3. N-th connection, which allows the connection of several web servers to the network. Their number depends on the level of network load. The number of computers that can work together on the network naturally increases significantly. Intermediate servers are conventionally given the names: "database server", "application server".

Thus, a local network with a complex N-structure connecting several servers and multiple clients provides an opportunity for better and ergonomic operation of all links in the network chain.
