Definition – What does ISP (Internet Service Provider) mean?

Internet Service Provider (ISP) provides access to the Internet. Whether you’re at work or home, each time you connect to your Internet connection, your connection is routed through an ISP. First, ISPs provide Internet access through the dial-up modems that took place over regular phone lines and was limited to 56 Kbps. In the late 1990s, Internet Service Providers began offering faster broadband Internet access via the DSL and cable modems. Most of the ISPs now offer high-speed fiber connections that provide Internet through fiber optic cables.

Glossary Web explains ISP (Internet Service Provider)

In order to link to an ISP, you need a modern modem and an active account, and when you connect a modem to the cable or telephone in your house, it automatically communicates with your ISP. The ISP verifies your details and assigns your modem an IP address. Once you get your IP address, you are linked to the Internet. You can use a router to connect several devices to the Internet. Each device is routed through the same modem; they will share all the same public IP address that is assigned by the ISP.

Internet Service Providers (ISPs) act as hubs on the Internet since they are connected directly to the Internet. Because of the great number of traffic ISPs handle, it requires high bandwidth connections to the Internet. In order to get faster speeds to customers, ISPs can add more bandwidth to their connection to prevent bottlenecks. That can be done by upgrading all the existing lines or adding new ones.
