Term: | 100BaseT |
ID: | 10942 |
Category: | A+ Hardware |
Date Added: | 04/12/03 |
Definition: | An Ethernet standard that operates at 100 Mbps and uses STP cabling (shielded twisted pair). Also called Fast Ethernet. Variations of 100BaseT are 100BaseTX and 100BaseFX. |
Term: | 100BaseT |
ID: | 11899 |
Category: | Cisco Systems |
Date Added: | 12/11/05 |
Definition: | 100-Mbps baseband Fast Ethernet specification using UTP wiring. Like the 10BaseT technology on which it is based, 100BaseT sends link pulses over the network segment when no traffic is present. However, these link pulses contain more information than those used in 10BaseT. Based on the IEEE 802.3 standard. See also Fast Ethernet and IEEE 802.3. |

Term: | 100BaseTX |
ID: | 10943 |
Category: | A+ Hardware |
Date Added: | 04/12/03 |
Definition: | The predominant form of Fast Ethernet. 100BaseTX runs over two pairs of wires in category 5 cable. |
Term: | 10Base2 |

Category: | A+ Hardware |
Date Added: | 04/12/03 |
Definition: | An Ethernet standard that operates at 10Mbps and uses small coaxial cable (RG58 or similar) up to 200 meters long per segment. Also called ThinNet. The "10" means 10 Mbps, "base" means "baseband" as opposed to radio frequency and "2" means a maximum single cable length of 200m. |
