Difference and connection between C S structure and B S structure

BS is the abbreviation of Browser Server.

It is to use a browser (such as IE) as the application client to operate the server. This is easy to use in a browser, but it doesn't have good validation of the input. There are not many logical implementations.

Local is just used to fetch the data and then most of the validation needs to be done by the commit server (most forums, ** is the model).

c s is the client server

The client software is a software that has a lot of logical verification, and the local verification is successful before it is submitted to the server (as is the case with most online games).

Main differences: B S is easy to maintain, and only needs to upgrade the server.

CS upgrades are difficult and require all clients to upgrade.

The bs structure uses the browser to display the interface like a normal **

CS is a windowed interface, like some online games

The CS structure is the server client structure. The CS structure usually takes a two-layer structure. The client is connected to the server through the local area network, accepts the user's request, and makes a request to the server through the network to operate the database.

The server accepts the client's request and submits the data to the client, which calculates the data and presents the results to the user.

With the popularity of the Internet and WWW, CS cannot meet the new requirements of the current global network openness, interconnection, information everywhere availability and information sharing, so the BS model emerges, that is, the browser server structure. It is an improvement of the CS architecture and can be said to belong to the three-tier CS architecture.

The differences between the C S structure and the B S structure are as follows: different hardware environments, different client software, and different user interfaces.

First, the hardware environment is different.

1. CS structure: CS structure is built on the basis of LAN, and then the LAN provides connection and data exchange services through special servers.

2. BS structure: BS structure is built on the WAN and does not need to be equipped with a special network hardware environment.

Second, the client software is different.

2. B S structure: Each client in the B S structure can process various information only through the browser, without installing client software.

3. The user interface is different.

1. C S structure: C S structure is built on the Windows platform, and the expression method is limited.

2. B S structure: B S structure is built on the browser, which has a richer and more vivid expression.

If you don't want to copy any answers, I'll tell you my own understanding C s structure refers to the client server, B s refers to the browser server.

For a simple example, QQ is a C s structure, and the usual ** browsing web is a B s structure.

The number of client upgrades in the CS structure is relatively large, for example, there is always a new version of QQ.

BS structure emphasizes response speed, imagine submitting an online payment form, half a day without response, I don't know how depressed the silver is crossed or lost.
