If you are interested in switching to DSL, you may be curious to know what DSL is all about and how it compares to dial-up. For the purpose of this comparison, we will assume that by DSL, we are talking about ADSL, the typical DSL connection available that uses a phone line to connect. Here are a few of the basics.
For starters, dial-up and DSL both connect using your land line phone line. Simply put, a dial-up modem converts the analog communication your phone line uses into digital information needed for your computer. The same thing happens on your phone company's end. Their modem converts the from digital to analog so it can travel on the phone lines. DSL, on the other hand, uses the same wires that your analog phone line used and bypasses the digital-analog-digital conversion dial-up must use.
Therefore, DSL transmits information much faster than dial-up, and works at a higher frequency (higher than can be detected by the human ear), and by doing so, it does not effect the analog communication (phone conversations, etc.) on those same lines.
The most obvious difference, other than the speed, is the price. The total monthly cost of dial-up is between 10 and 20 dollars a month with little or no additional fees including set up or equipment fees. DSL has a monthly fee somewhere between 20-100 dollars a month (based on speed desired and location), not including the price of equipment, installation, and other fees such as repair plans, technical support, or contract fees.
Most computers have a dial-up modem already installed on the computer, so there aren't typically many equipment costs associated with dial-up. Other than a land line and a phone cord, that is the extent of the "equipment" and "installation" costs for dial-up.
Availability and transportability are two categories where dial-up exceeds DSL. Connecting to the internet with most dial-up services is available to any computer that has a land line phone. It is not confined to the home where the DSL modem is installed.
DSL is only available in very limited areas. DSL is rarely available in rural areas because they are too far from the phone company's central office. The choices of connection speeds on DSL could cut in half based solely on your locations. Often, a few hundred feet means the difference of DSL or no DSL for suburban homes.
DSL and dial-up can be provided both by your phone company or through your phone company. While you can set up nearly any dial-up service with any analog phone service, DSL is usually only available with your phone company or a DSL company that partners with your phone company.
Many phone companies will not let any other DSL company use their phone lines, so this could even further limit or prevent you from getting DSL. If they do, further problems can occur in the process of communication during the activation period and the resolving of technical issues. Even with no complications, DSL usually takes at least several days to set up.
Dial-up has a very simple set up procedure that takes about half an hour or less (unless you are mailed a setup CD, which is often not necessary). Since it is so simple to set up, you can easily move the connection, set up multiple connections, and take your service with you when you travel or move. Rarely does your phone company need to be involved or even notified, other than to make sure your access number is a local call.
DSL is a fast, dedicated connection for those who require it for gaming, downloading, and streaming of videos, etc. Dial-up excels in price, availability, and simplicity for people who need to save money or don't have many other options.
