High-speed Internet: What's best for you? Here's some information to help you decide:

DSL (digital subscriber line)

Lucent Technologies. (ENLARGE)

Color-coded glass fibers - which transmit voice and data as light impulses - are at the core of this fiber-optic cable produced at a Lucent Technologies plant in Norcross. The fiber strands are surrounded by layers designed to protect them from moisture and gnawing rodents once the cable is buried underground.

Best for those who ... check e-mail sometimes and browse Web sites. If the basic speed of 768 kilobits per second (kbps) is too slow, faster speeds, like 3 megabits per second (mbps), are available.

Cost and speed: Around $20 a month for 768 kbps. Downloads a 1-megabyte photo in about 10 seconds.

Keep in mind: DSL works through copper phone lines, so if your phone is out of service, your Internet connection might be, too.

Cable

Best for those who ... regularly read and send e-mails; enjoy downloading music and watching videos online.

Cost and speed: Around $40 a month for 6 mbps. Downloads a 1-megabyte photo in about 1.5 seconds.

Keep in mind: You and your neighbors share the cables that deliver the connection, so you may hit a few speed bumps during peak usage hours (such as after dinner).

Fiber optics

Best for those who ... share a lot of photos and videos online and download or upload movies and other large files from the Web.

Cost and speed: About $53 a month for a 15-mbps connection. Downloads three 1-megabyte photos in about 1.6 seconds.

Keep in mind: Fiber optics (super-speedy networks of glass wires) are not available everywhere. (Verizon FiOS, the largest national provider, is available in 16 states so far.)
