10BASE-T 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.
100BASE-T 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.
1000BASE-T A designation for the type of wiring used by Ethernet
networks with a data rate of 1000 Mbps.
binary 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 11010001.10111111.00000100.11110000 in
binary. See also bit, IP address, network mask.
bit Short for “binary digit,” a bit is a number that can have two
values, 0 or 1. See also binary.
bps bits per second
CoS Class of Service. Defined in 802.1Q, the value range is from
0 to 7.
DSCP Differentiated Services Code Point.
The six most significant bits of the DiffServ field in IP header
is called as the DSCP. The available DSCP values in GigaX
are 0, 8, 10, 16, 18, 24, 26, 32, 34, 40, 46, 48, and 56.
broadcast To send data to all computers on a network.
download To transfer data in the downstream direction, i.e., from the
Internet to the user.
Ethernet 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.
filtering 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.
