The 10-Mbps baseband Ethernet specification that uses two pairs of twisted-pair
cabling (Category 3 or 5); one pair for transmitting data and the other for receiving
data.
An electrical circuit that is represented by means of continuous, variable physical
quantities (such as voltages and frequencies), as opposed to discrete representations
(like the 0/1, off/on representation of digital circuits).
Address Resolution Protocol is a protocol for mapping an Internet Protocol address (IP

Frames from one LAN are forwarded across a bridge to a connected LAN, although
filtering can be employed to selectively forward frames. Bridging works similar to the
way repeaters work except that bridges forward frames based on their MAC (Medium
Access Control) addresses which are hardware-level addresses of NICs (Network
Interface Cards).
A set of bits that represent a single character. There are 8 bits in a Byte.
Call Detail Record. This is a name used by telephone companies for call-related
