|
Ethernet |
A series of LAN standards defined by the IEEE, originally invented by Xerox Corporation and developed jointly by Xerox, Intel, and Digital Equipment Corporation. |
|
|
IEEE |
Institute of Electrical and Electronics Engineers. A professional organization that develops communications and network standards, among other activities. |
|
|
Wireless LAN / Wired LAN |
A local-area-network (LAN) that physically transmits bits using radio waves. The name "wireless" compares these LANs to more traditional "wired" LANs, which are LANs that use cables (which often have copper wires inside.) |
|
|
Ethernet frame |
A generic term for any physical link between two Ethernet nodes, no matter what type of cabling is used. |
|
|
10BASE-T |
The 10-Mbps baseband Ethernet specification using two pairs of twisted-pair cabling (Categories 3, 4, or 5): One pair transmits data and the other receives data. 10BASE-T, which is part of the IEEE 802.3 specification, has a distance limit of approximately 100 m (328 feet) per segment. |
|
|
100BASE-T |
A name for the IEEE Fast Ethernet standard that uses two-pair copper cabling, a speed of 100 Mbps, and a maximum cable length of 100 meters. |
|
|
1000BASE-T |
A name for the IEEE Gigabit Ethernet standard that uses four-pair copper cabling, a speed of 1000 Mbps (1Gbps) and a maximum cable length of 100 meters. |
|
|
Fast Ethernet |
The comman name for all the IEEE standards that send data at 100 megabits per second. |
|
|
Gigabit Ethernet |
The common name for all the IEEE standards that send data at 1 gigabit per second. |
|
|
Ethernet link |
A generic term for any physical link between two Ethernet nodes, no matter what type of cabling is used. |
|
|
RJ-45 |
A popular type of cabling connector used for Ethernet cabling. It is similar to the RJ-11 connector used for telephone wiring in homes in the United States. RJ-45 allows the connection of eight wires. |
|
|
Ethernet Port |
A generic term for the opening on the side of any Ethernet node, typically in an Ethernet NIC or LAN switch, into which an Ethernet cable can be connected. |
|
|
Network Interface Card (NIC) |
A computer card, sometimes an expansion card and sometimes integrated into the motherboard of the computer, that provides the electronics and other functions to connect to a computer network. Today, most NICs are specifically Ethernet NICs, and most have an RJ-45 port, the most common type of Ethernet port. |
|
|
Straight-through cable |
In Ethernet, a cable that connects the wire on pin 1 on one end of the cable to pin 1 on the other end of the cable, pin 2 on one end to pin 2 on the other end, and so on. |
|
|
Crossover cable |
An Ethernet cable that swaps the pair used for transmission on one device to a pair used for receiving on the device on the opposite end of the cable. In 10BASE-T and 100BASE-TX networks, this cable swaps the pair at pins 1,2 to pins 3,6 on the other end of the cable and the pair at pins 3,6 to pins 1,2 as well. |
|
|
Ethernet address |
A 48-bit (6-byte) binary number, usually written as a 12-digit hexadecimal number, used to identify Ethernet nodes in an Ethernet network. Ethernet frame headers list a destination and source address field, used by the Ethernet devices to deliver Ethernet frames to the correct destination. |
|
|
MAC address |
Media Access Control. The lower of the two sublayers of the data link layer defined by the IEEE. Synonymous with IEEE 802.3 for Ethernet LANs. |
|
|
Unicast address |
Generally, any address in networking that represents a single device or interface, instead of a group of addresses (as would be represented by a multicast or broadcast address). |
|
|
Broadcast address |
Generally, any address that represents all devices, and can be used to send one message to all devices. In Ethernet, the MAC address of all binary 1s, or FFFF.FFFF.FFFF in hex. |
|
|
Frame Check Sequence |
A field in many data link trailers used as part of the error-detection process. |
