network Programming 和 web programming分别是什么意思

To understand the difference between the two "programming"s,you should under the difference between "network" and "web" first。In computer science,network is the mechanism of or media for information transmission,exchanging,or a group of computers and devices connected for such purposes。The objective of network programming is to fulfill these purposes。It is more related to signal,hardware,message,etc。For example,telephone switching system,wireless network communication,etc。,are all the tasks of network programming。Web programming,on the other hand,is on a more abstract level。Its mechanism is based on that of the network programming。In web programming,you never worry about how this device talks to that device,how should the talk be taken on so as to not lose information or to avoid interruption of trasmission and so on。The purpose of web programming is to accomplish such missions as doing tasks usually done only on your computer in an online way。For example,an online bank,web seminar,BaiDu Hi,they all are web programming。In a word,what you see and use everyday on the Internet,and how and in what presentation form they are shown on your computer,are the targets of web programming,while how the content you see and use is transmitted on the network and to your computer is the task of network programming。
