The theoretical maximum speed of a typical dial-up modem is 56 kilobits per second (56 Kbps),
which may sound like something extra special, but it??™s not. In most cases, you won??™t get very
close to the full theoretical speed because of phone line noise and other factors. At this speed,
tasks that are typical for today??™s Internet users, such as video conferencing and watching movie
trailers, won??™t be a pleasant experience at all. Some services, like using a Voice over Internet
Protocol (VoIP) phone carrier such as Vonage, are impossible at dial-up speeds. Another mark
against dial-up is that the connection isn??™t always on, and when you are connected, your phone
line is tied up by the modem; to make or receive a call, you must suspend the Internet connection.
The positive side to this kind of connection is the price, which is lower than any broadband
service, but the difference in cost between dial-up and broadband is fairly negligible these days.
Some dial-up ISPs offer free Internet access, but the time allotted is limited and you have to
contend with advertisements, which is what the ISP uses to support this free service.
