The registrations are subject to limitations established by Network Solutions, including prohibitions on trademark infringements and previously assigned names. For the most part, however, the second level domain names are selected by the registrants. One of the important differences between e-mail and the World Wide Web is the method of accessing them. E-mail can be directed to a recipient without a request for the information. The Web on the other hand provides information which can only be accessed through a search of some type.
Individuals can find web sites by going directly to the URL, if it is known.
Alternatively, the sites can be accessed through search engines, using key words, or be accessed through hypertext links from other sites. Note, however, that e-mail and web sites are interactive with one another. Web sites permit threaded discussions that are carried out through e-mail, for example. Web sites typically have home pages, or that part of the site that gives directions to the web site as a whole. It is important to note that the home page is one of the parts of a web and not a portal through which an Internet user must pass.
