answer:There are four categories of internet service. Dial-up service, Cable service, DSL service and T-1 service. The availability, speeds and prices vary. Dial-up is the least expensive, most available, but the slowest (56 Kbps). Cable and DSL are relatively similar in availability, price and speed, depending on variables like, how many people in your neighborhood are using the circuit you are on at the same time you are online….how far away from the telephone company’s equipment site (called the “CO”, or “Central Office”) you live. Your cable provider choices are usually limited, because it is typical for a city to award the contract for cable service in any given area to only one provider, who then is your only choice for cable service: “Deal with us, or do without,” could be their motto. DSL service is usually offered through the local Bell phone company or through other companies that lease the service from the Bell phone company. T-1 service is the fastest and the most expensive. 1.5 Mbps, dedicated to your site, not shared. Not available in all locations. Costs between $700 and $1,200 per month.
