The Internet is a web of linked computer networks set up initially by the US government. Each computer network on the Internet shares certain data formats and commands, so that anyone on a member network can send electronic mail (email) to anyone else. To enter the Internet, one must first join (an establish an account on) one of the thousands of member networks worldwide. Those networks (free to students and faculty), or a national commercial network such as Compuserve or America On Line. These charge monthly fees plus $4-$12 per hour. Prodigy does not yet offer Internet services, and America On Line has plans to add them.
