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.
The dynamic host configuration protocol (DHCP) is an addressing protocol for TCP/IP networks.
IP addresses are leased to individual computers on the network from a DHCP server. DHCP allows users to move to different locations on a network without having to bother a network administrator (and they hate being bothered) to manually assign a new IP address. DHCP is useful in homes with several computers sharing a single high-speed internet connection.
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.
Short for internet service provider, an ISP owns and operates all of the equipment (telephony, digital cable, servers, etc.) that allow you to connect to the internet from your home or office.
Most ISPs sell access to their services for a small monthly fee, which you can access by connecting to your ISP’s computer network through a phone or cable line.
