Ethernet
Ethernet is the most popular physical layer LAN technology in use today. It defines the number of conductors that are required for a connection, the performance thresholds that can be expected, and provides the framework for data transmission.
Standard Ethernet (10Base-T) network can transmit data at a rate up to 10 Megabits per second (10 Mbps).
Fast Ethernet (100Base-T) standard (IEEE 802.3u) has been established for Ethernet networks that need higher transmission speeds. This standard raises the Ethernet speed limit from 10 Mbps to 100 Mbps with only minimal changes to the existing cable structure.
Gigabit Ethernet (1000Base-T) was developed to meet the need for faster communication networks with applications such as multimedia and Voice over IP (VoIP). Also known as “gigabit-Ethernet-over-copper” or 1000Base-T, GigE is a version of Ethernet that runs at speeds 10 times faster than 100Base-T.
10 Gigabit Ethernet (10GBase-T) is the fastest and most recent of the Ethernet standards. IEEE 802.3ae defines a version of Ethernet with a nominal rate of 10Gbits/s that makes it 10 times faster than Gigabit Ethernet.
Ethernet is popular because it strikes a good balance between speed, cost and ease of installation. These benefits, combined with wide acceptance in the computer marketplace and the ability to support virtually all popular network protocols, make Ethernet an ideal networking technology for most computer users today.
The Institute for Electrical and Electronic Engineers developed an Ethernet standard known as IEEE Standard 802.3. This standard defines rules for configuring an Ethernet network and also specifies how the elements in an Ethernet network interact with one another. By adhering to the IEEE standard, network equipment and network protocols can communicate efficiently.
Standard Ethernet Code
In order to understand standard Ethernet code, one must understand what each digit means. Following is a guide:

For example: 100BASE-TX indicates a Fast Ethernet connection (100 Mbps) that uses a twisted pair cable capable of full-duplex transmissions.

Standard Ethernet Code
In order to understand standard Ethernet code, one must understand what each digit means. Following is a guide:
| Position in code and meaning | |
|---|---|
| 10 | at the beginning means the network operates at 10Mbps. |
| BASE | means the type of signaling used is baseband. |
| 2 or 5 | at the end indicates the maximum cable length in meters. |
| T | the end stands for twisted-pair cable. |
| X | at the end stands for full duplex-capable cable. |
| FL | at the end stands for fiber optic cable. |
For example: 100BASE-TX indicates a Fast Ethernet connection (100 Mbps) that uses a twisted pair cable capable of full-duplex transmissions.
