Glossary

Category 5 unshielded twisted pair (UTP) cabling. An Ethernet network 
operating at 10 Mbits/second (10BASE-T) will often tolerate low quality 
cables, but at 100 Mbits/second (10BASE-Tx) the cable must be rated as 
Category 5, or Cat 5 or Cat V, by the Electronic Industry Association (EIA). 
This rating will be printed on the cable jacket. Cat 5 cable contains eight 
conductors, arranged in four twisted pairs, and terminated with an RJ45 type 
connector. In addition, there are restrictions on maximum cable length for 
both 10 and 100 Mbits/second networks.

NETGEAR.com is the domain.
