Dial up Internet service providers, or ISPs, are mostly organizations, companies or business that provides people who want access to the information superhighway the chance to do so. People who use dial up ISP are provided immediate access to the Internet through their own telephone lines. All you need is a computer, a telephone line and a modem that serves as the medium and channel between the phone line and the computer. Dial up ISPs provides users Internet connections that are around 56 kilobytes per second, or less.

Dial up ISPs also provide other services they are not just limited to dial up access. They also provide Internet transit, domain name registration and domain name hosting. These dial up ISPs are mostly telephone companies, but not all of them are.

This sluggishness can be particularly annoying to people who are use to accessing the Internet through fast DSL, cable or broadband subscriptions. The average Internet speed through dial up ISP services is only 30 kilobytes per second, or 50 at most. But many people like dial up ISP because it is less expensive; if you don't need speed, use dial up.
