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.

binary

The “base two” system of numbers, which 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 11010001.10111111.00000100.11

110000 in binary. See also bit, IP address, network mask.

bit
