Glossary

The following is a list of common cable and networking terms.

Amp-hour (Ah)

A measure of battery capacity. For example, a 1.0Ah battery can nominally

supply one Ampere of current for one hour.

Category 5 (Cat5)

A high-quality type of cable, used for Fast Ethernet (100BaseT) connections.

When purchasing Ethernet cables, always look for Category 5 cable.

Coaxial cable (coax)

A thin wire, used to connect your television and Telephony Modem to the

cable TV system. You can buy coax from any electronics retailer and many

discount stores.

CPE

Customer Premise Equipment. This is the equipment that is plugged in to the

Telephony Modem; typically a computer or hub.

Cross-over

An Ethernet cable used to connect two hubs (or a hub and a cable modem)

together. Also, some Ethernet hubs may have built-in cross-over on one or

more ports (which eliminates the need for a cross-over cable).

DHCP

Dynamic Host Configuration Protocol. An IP protocol used to provide an IP

address and location of services (such as DNS and TFTP) needed by a de-

vice connecting to the network. DHCP allows the cable company to configure

your computer’s networking software for you.

DNS

name (such as www.example.com) with an IP address.
