LIS 525 - ISPs and Web Hosting

What is an ISP?

An ISP (Internet Service Provider), or IAP (Internet Access Provider), is a company that provides access to the Internet.

ISPs are connected to the rest of the Internet through Network Access Points (NAPs).

Users may be individuals or large or small companies or other organizations.

Kinds of connection that customers may use include dial-in at different speeds (e.g., 56Kbps), DSL (Digital Subscriber Line) and ISDN (Integrated Services Digital Network) (which both operate over copper telephone lines), cable modem, T1 (DS1) or T3 leased line, and OC (Optical Carrier) fiber optic line.

What is Web hosting?

Web hosting (or Web site hosting) is the provision of equipment and services to maintain, and make accessible over the Internet, files for one or more Web sites.


Rates vary from "free" up, depending on the ISP or Web hosting service and the services provided. Additional charges are often incurred for setup, for use beyond certain limits, and for extra services such as Web hosting. Lower rates may be given to charities and other nonprofits.


Various services may be provided.
