The difference between B/s architecture and C/s architecture

Difference

2. Different hardware environments:

   c/S is generally established in a dedicated network, a small range of network environment, LAN and then through a dedicated server to provide connectivity and data exchange services. b/S is built on the WAN, need not be specialized network hardware environment, example with telephone Internet, renting equipment. Information is managed by itself. Have more than C/s to adapt to the range, generally as long as there are operating systems and browsers on the line

4. The security requirements are different:

   c/S is generally oriented to a relatively fixed user group, the ability to control information security is very strong. Generally highly confidential information system using C/s structure is suitable. Can be published through the B/s part of the public information.

   b/S is built on the wide area network, the security control ability is relatively weak, facing is an unknown user group.

6. Different from the program architecture:

   c/S program can pay more attention to the process, the authority can be multi-level check, the system running speed can be less considered.

   b/S multiple considerations for security and access speed are based on the need for more optimization. More than C/s has higher requirements B/s structure of the program architecture is the trend of development, from the MS. NET series of BizTalk Exchange 2000, etc., fully support the network component Building system. SUN and IBM push the JavaBean component technology, so that b/s more mature.

8. Software reuse differs:

   c/S program can inevitably be considered as a whole, the reuse of components is not as good as the reuse of components under B/s requirements.

   The multi-structure of B/s pair requires the relative independent function of the component. Can be reused relatively well. You can reuse the table you bought, not the stone table on the wall.

10. System maintenance is different:

    System maintenance is the software life cycle, the cost is big,-------important

    Due to the integrity of the C/s program, it is necessary to investigate the problem and upgrade the system. Upgrade is difficult. Could be a whole new system.

    b/S components, components of individual replacement, to achieve seamless upgrade of the system. Minimal system maintenance overhead. Users can download and install themselves from the Internet to achieve upgrades.

12. Different handling issues:

    c/S program can handle the user face fixed, and in the same area, security requirements of high demand, operating system-related. Should all be the same system.

    b/S is built on the wide area network, facing different user groups, dispersed area, this is the C/s can not be made. Minimal relationship to operating system platform.

14. User interface is different

    C/S is established window platform, the performance method is limited, the programmer generally requires higher

    b/S is built on the browser, there is more rich and vivid expression way to communicate with users. And most of the difficulty is reduced, reducing development costs.
