What front-end project is?

What the preceding project is?
Front-end and back-end engineer engineering software development work to be done!
Software is divided into two architectures C / S and B / S.
We mainly engaged in the development of B / S's.
Software architecture are c / s and b / s.
c / s client / server Generally, we use software such as software architecture, it is the qq, 360, offioce. c represents the client, user through the client software. s presentation server, the server is responsible for processing business logic website. c / s Features: 1 before using the software must be installed. 2 . When a software update servers and clients are updated simultaneously. 3 .c / S software can not be used across platforms 4.c / s architecture, its own protocol software client uses, relatively safe.
b / s, what browser / server) that?
b / s using a browser as a client by using a browser to access the web page of the form to use software, such as known almost Jingdong Taobao. Characterized by using a browser without installing direct access to the specified URL, software updates, the client does not need to update, the software can be used across platforms, as long as there are systems you can use the browser. b / s architecture software, using a common use http protocol between the client and the server, are relatively safe.
