A designation for the type of wiring used by Ethernet
networks with a data rate of 10 Mbps. Also known as
Category 3 (CAT 3) wiring. See also data rate, Ethernet.
A designation for the type of wiring used by Ethernet
networks with a data rate of 100 Mbps. Also known as
Category 5 (CAT 5) wiring. See also data rate, Ethernet.
A designation for the type of wiring used by Ethernet
networks with a data rate of 1000 Mbps.
The "base two" system of numbers, that uses only two
digits, 0 and 1, to represent all numbers. In binary,
the number 1 is written as 1, 2 as 10, 3 as 11, 4 as
100, etc. Although expressed as decimal numbers for
convenience, IP addresses in actual use are binary
numbers; e.g., the IP address 209.191.4.240 is 1101000
1.10111111.00000100.11110000 in binary. See also bit, IP
address, network mask.
Short for "binary digit," a bit is a number that can have
two values, 0 or 1. See also binary.
bits per second
Class of Service. Defined in 802.1Q, the value range is
from 0 to 7.
To send data to all computers on a network.
To transfer data in the downstream direction, i.e., from
the Internet to the user.
The most commonly installed computer network
technology, usually using twisted pair wiring. Ethernet
data rates are 10 Mbps and 100 Mbps. See also
10BASE-T, 100BASE-T, twisted pair.
To screen out selected types of data, based on filtering
rules. Filtering can be applied in one direction (ingress or
egress), or in both directions.
A rule that specifies what kinds of data the a routing
device will accept and/or reject. Filtering rules are defined
to operate on an interface (or multiple interfaces) and in a
particular direction (upstream, downstream, or both).
