The paper expatiates the concepts and characteristics of invisible web,expatiates the reason of its forming in the information navigation system.

This paper introduces the definition,characteristics,formation reasons and types of invisible web,and expounds the retrieval tactics of the invisible web.

This paper introduces the basic conception of invisible web,and recognizes the reason how it appeared.

This paper analyzes varieties of methods in net-scan technology, classifies net scan by area, headstream, speed, content to analyze the problems during those net-scan technology, in order to guide the design of net scanner and to its using.

This paper first puts forth a classification of network scanning techniques from four aspects:scope, headstream,speed and content,provides specific application of network scanning,and finally builds the sys- tem structure and software running flow chart of a net scanner.
