Our Dialup Internet Services

Dial-up Internet access is a connection type that operates through a standard telephone line. By running the telephone line to a modem device in the computer and configuring it to dial a specific phone number, the computer can connect to the Internet. This connection type is usually inexpensive, but slow, and may not be adequate for users who use the web for multimedia and other high-bandwidth applications.

The modem is controlled by software in the computer which allows the user to set up a profile for the ISP, which will tell the modem what phone number to call and how to communicate with the service. Once the modem calls the phone number and makes a connection, a "handshake" takes place in which information is exchanged between the computer modem and the remote server. The subscriber chooses a username and password or has one assigned by the ISP, and this information is transmitted by the modem to allow the user to connect to the service.

Advantages

Dial-up service is usually the least expensive type of Internet access, and may even be free in some places, although often with advertising added to it. It is also available to anyone who has a phone line, so there's no need for a separate connection to be added to a home. Most computers already have modems installed, so there's often no additional hardware to buy to start the service.

Disadvantages

The biggest problem with dial-up Internet is that it's slow. Due to the limited bandwidth, which is the ability for the modem to send and receive data, downloading large files can take a very long time. Most dial-up services operate no faster than 56 kilobits per second (kbps); downloading a file that's several megabytes (MB) large would likely take several hours, which makes it too slow for streaming video or music. Saving copies (called "caching") of frequently visited pages and other software tricks can speed up the experience in some cases, but most people who want to access a lot of multimedia will likely find the speed unsatisfactory.

Dial-up Internet also depends on the regular telephone line, which means that a home must pay for regular phone service to connect. The phone cannot be used for any other purpose, like voice calls, while the computer is using the line in most cases, and any disruption to the line will typically break the connection. In most situations, the user must dial in to the service each time he or she wants to get online, which means that the connection isn't always on; it's also likely to disconnect if the connection isn't being used for some period of time. In addition, only one computer can use the phone line at a time.
