A bridge (not to be confused with a router) is a data network device used to connect two network segments of different protocols.

For example, if you want computers on a TCP/IP network to talk to computers on a token ring network, you need a bridge to connect the two segments.

Broadband is a general term used to describe any high-speed, high-bandwidth, “always on” internet connection.

Cable modems, DSL modems, satellite link-ups, and T1 lines are all broadband devices. Dial-up modems and other low-bandwidth devices are called “narrowband.”

Channels refer to the conduits in which to deliver content or data.

In web development, channels may refer to the data feeds allowing content onscreen without reloading the page or redrawing the whole screen. Channels may also refer to the paths a computer uses to transmit information between peripherals.

A digital subscriber line, or DSL, is a communications technology that allows data to travel at very high speeds over standard telephone wire without interrupting normal telephone service.

The primary market for DSL is the home office since the technology makes it easy for residential homes to receive high-speed internet access at a reasonable price. DSL speeds, on the average, run at about 600kbps for downstream and 128kbps for upstream.
