Appendix A Glossary

Address mask
A bit mask used to select bits from a set of IP address for subnet addressing. The mask is 32 bits long and
network devices uses these bits to identify which bits in an IP address are network number, and which bits are
hosy number. Address mask is also known as subnet mask.
AAL5
ATM Adaptation Layer 5 - This layer maps higher layer user data into ATM cells, making the data suitable for
transport through the ATM network.
ADSL
Asymmetric digital subscriber line.
ATM
Asynchronous Transfer Mode - A cell-based data transfer technique in which channel demand determines packet
allocation.
ATM offers fast packet transfer technology, real time; demand led switching for efficient use of network resources.
AWG
American Wire Gauge - The measurement of the thickness of a wire.
Bridge
A device connects two or more physical networks and forwards packets between them. Bridges can also filter
packets, that is, to forward only certain traffic. Related devices are: repeaters which simply forward electrical
signals from one network to the other, and full-fledged router which make routing decisions based on several
criteria.
Broadband
Characteristic of any network multiplexes independent network carriers onto a single cable. Broadband
technology allows several networks to coexist on one single cable; traffic from one network does not interfere with
traffic from another. Broadcast a packet delivery system where a copy of a given packet is given to all hosts
attached to the network. Example: Ethernet. **Ethernet is based on basdband technology! It's recommended to
use cable TV as example for 'multiplexes independent network carriers onto a single cable'.
CO
Central Office. Refers to equipment located at a Telco or service provider's office.
