After introducing the main definitions of the Internet in the first chapter and after exploring how we can speak of the Internet from a sociological , technological and economic point of views we have arrived at a definition of the Internet as a separate industry. In fact, we have proposed a model representative of the Internet industry consisting of five stratigraphic layers that forms the basis of the framework LIIF..
Each level is connected with the adjacent one that represents a continuum between the parties .
The layers introduced into the framework LIIF are distinguished according to this scheme:
- Infrastructure layer, the layer that includes manufacturers of equipment and materials needed for the infrastructure of the Internet, those involved in the creation and management of the infrastructure, ie all the technological infrastructure platforms that support Internet;
- Access layer,the layer that includes the access operators (ISP), Internet enabled device manufacturers, operating system vendors and software free, meaning that all access platforms to the Internet;
- IT layer,the layer that includes the software vendors to develop web applications for the Internet commerce, content management systems (CMS), ie all software platforms based on the Internet;
- Intermediary layer, the layer that includes the intermediaries that handle technology and online services, such as search engines, payment intermediaries, platforms enabling transactions between buyers and sellers, online advertising platforms, ie all brokerage platforms of the Internet;
- Content layer, the layer that includes operators who offer content and sell products and services, ie all content platforms of the Internet .
In this chapter we analyze the distinctive features of each of the above layers.
