(1) See in-system programmable.
(2) (Internet Service Provider) An organization that provides access to the Internet. Connection to the user is provided via dial-up, ISDN, cable, DSL and T1/T3 lines. Customers are generally billed a fixed rate per month, but other charges may apply.
Your Own Web Site
ISPs often host a small Web site for their customers, allowing you to have a presence on the Web. However, the Web site may be limited to a maximum number of pages, and the domain name of the ISP becomes part of the customer's URL address. For a fee, many ISPs will host Web sites and use your proprietary domain name.
Some of the older ISPs, such as AOL (America Online) and MSN (Microsoft Network), also provide proprietary databases, forums and services in addition to the on-ramp to the Internet. See IXP and backbone.
How They're Connected
Small ISPs hook into regional ISPs or directly into major backbone providers. This diagram shows a local ISP confined to a single county, and a regional ISP confined to a state. In practice, ISP networks often have irregular boundaries that span jurisdictions.

This diagram shows how a typical, small ISP might be connected to the Internet.
