Local bulletin boards.

Bulletin board systems (BBS) are frequently free because they are run by enthusiasts and sponsored by user groups or small businesses. The first time you make a BBS connection you are required to register your name, address, phone number and other information such as the kind of computer and modem you are using. The person who administers the BBS is called sysop (system operator). You can use a BBS to download artwork, games and programs, or you can participate in ongoing discussions. You can also upload (send) programs, hut make sure they are shareware or public domain programs.

Online service providers.

To gain access to the Internet you must first open an account with an Internet service provider (ISP) or a commercial online service provider. Both offer Internet access, but the latter provides exclusive services.

• Internet service providers usually offer access to the Web and newsgroups, an e-mail address, a program to download files from FTP sites, and IRC software so that you can have live chats with other users. Most ISPs charge a flat monthly or annual fee that gives you unlimited access to the Internet,

• The main commercial online services are America Online, CompuServe, Prodigy and the Microsoft Network. They differ from dedicated JSPs in two ways: (1) they use a smooth, easy-to-use interface, and (2) they have extra services for members only (but they charge higher prices). For example, they offer airline reservations, professional 70 forums, online shopping and stories for children. They also let you search their online encyclopedias and special databases.
