ISP = Internet Service Provider

A company that provides businesses and consumers access to the Internet, typically for a monthly service fee. Some ISP's also provide additional services such as e-mail and web site hosting. The largest ISP is America On Line (AOL) which is used by approximately 20 million consumers to connect to the Internet

Internet Service Provider houses the network, computers, servers, modems, T1, and other relevant equipment to provide you with a quality connection to the Internet. .

The speed of your connection will depend on the bandwidth of the hardware you use to connect (the options include air, glass, cable, or cord).

ISPs have a wide range of prices and packages to choose from. For example, there are accounts tailored for large companies, providing a direct connection from the company's network to the Internet, and there are accounts for individuals who only plan on moderate usage, connecting by dial-up. The best thing to do when choosing an ISP is to be sure it has a local access number so you won't have to dial long-distance (or pay toll charges) to connect. Also try to get an account that offers unlimited access, as well as free Web space for you to house your own Web site.

ISPs themselves are connected to one another through Network Access Points (NAPs).

ISPs are also called IAPs (Internet Access Providers).
