10BASE-T
IEEE 802.3 specification for 10 Mbps Ethernet over Category 3, 4, or 5 twisted pair wiring.
100BASE-Tx
IEEE 802.3 specification for 100 Mbps Fast Ethernet over Category 5 twisted pair wiring.
1000BASE-T
IEEE 802.3 specification for 1000 Mbps Gigabit Ethernet over Category 5 twisted pair wiring.
802.1Q
IEEE specification for the operation of Virtual LAN (VLAN) Bridges that permit the definition, operation
and administration of Virtual LAN topologies within a Bridged LAN infrastructure.
802.3
The IEEE standard defining the hardware layer and transport layer of (a variant of) Ethernet. The maximum
segment length is 500m and the maximum total length is 2.5km. The maximum number of hosts is 1024.
The maximum packet size is 1518 bytes.
802.3ab
Gigabit ethernet over Copper (also known as 1000BaseT) is an extension of the existing Fast Ethernet
standard. It specifies Gigabit Ethernet operation over the Category 5e/6 cabling systems already installed,
making it a highly cost effective solution.
802.3u
The IEEE committee working on standards for Fast Ethernet.
ADSL
Short for asymmetric digital subscriber line, a technology that allows data to be sent over existing copper
telephone lines at data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and
from 16 to 640 Kbps when sending data (known as the upstream rate).
