Network information resources is: refers to the electronic resource data in the form of text, images, sound, animation, and other forms of information stored in optical, magnetic and other non-printed media, the use of computers through the network for the release, transmission, storage of the sum of all types of information resources.

Advantages:

Storage digitization, information resources from the text on the paper into the magnetic media on the electromagnetic signal or optical media on the light information, so that the storage and transmission of information, query is more convenient, and the information stored in a high density, high capacity, and can be reused without loss.

The information in the form of digitization can be processed at high speed in computers and transmitted over long distances through information networks.

Since the information storage form and data structure have the characteristics of universality, openness and standardization, it is easier to duplicate and distribute network information resources, therefore, without considering the case of copyright, a point of resources can be unlimited copies at the same time to serve an unlimited number of users.

The network breaks the time and space boundaries of transmission, users can access information resources at any time, any place, so that the network information resources dissemination of time and space range has been maximized to extend and expand. Several users can simultaneously **** with the same information resources.
