There is no central body that administers the Net. Caveat emptor prevails. Users can logon to computers miles away, transfer files, exchange messages and basically share information. The Internet provides access to tens of thousands of databases, including newspapers, journals, magazines, books, and public domain software in thousands of subject areas. It also has thousands of news groups that enable users with similar interests to communicate with each other and learn about the latest developments in their areas of interest.
All Internet users can communicate with each other.
Today it refers to the complex of hypertext servers, available over the Internet, that allow text, graphics, sound files, etc. to be mixed together. Beginning with a home page, you are linked, or webbed, to other related pages which in turn are linked to other related pages, infinitum. There is not a top page to the Web, nor a hierarchical structure, hence the vision of a spider's web spanning outward in many directions is appropriate to describe its structure. As you find pages of interest, you can save them as bookmarks to view in future sessions. You can also view your session history and revisit a place you saw just 20 minutes ago.
