What is b/s, what is the C/s architecture?

C/S architecture

C/S is also known as Client/server or client/server mode. Servers typically employ high-performance PCs, workstations, or minicomputer, and employ large database systems such as Oracle, Sybase, Informix, or SQL Server. The client needs to install the dedicated client software (the rich client).

Advantages and disadvantages of C/s architecture

Advantages:
The 1.C/S architecture gives full play to the processing power of the client PC.
2. Security can be easily ensured, multi-layer certification is not difficult.
3. Because there is only one layer of interaction, the response is faster.

4. There is a general limit to the operating system of the client

Disadvantages:
1. Narrow application, usually used in LAN.
2. Fixed user group. Because the program needs to be installed to use, it is not suitable for some unknown users.
3. High maintenance costs and an upgrade occurs, all client programs need to be changed.

b/S architecture

b/S is an abbreviation for Brower/server, as long as the client installs a browser (Browser), such as Firefox, Google Chrome, or Internet Explorer, the server installs Oracle, MySQL, or SQL Server and other databases. The browser interacts with the database through the Web Server (thin client).

Advantages and disadvantages of B/s architecture

Advantages:
1. The client does not need to be installed and has a Web browser.
2.BS architecture can be placed directly on the WAN, through a certain degree of access control to achieve the purpose of multi-client access, interactivity is strong.
The 3.BS architecture does not need to upgrade multiple clients to upgrade the server.

Disadvantages:
1. The biggest problem with the BS architecture is the huge cost of design required for speed and security.
2. Client-side interaction is a request-response pattern that usually requires a refresh of the page, which is not a customer's pleasure to see. (This problem has been eased somewhat after Ajax popularity)
