21 Facts About Ethernet port
2.
Over time, Ethernet port has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET.

3.
Original 10BASE5 Ethernet port uses coaxial cable as a shared medium, while the newer Ethernet port variants use twisted pair and fiber optic links in conjunction with switches.

4.
The Ethernet port standards include several wiring and signaling variants of the OSI physical layer.
| FactSnippet No. 1,200,665 |
5.
Per the OSI model, Ethernet port provides services up to and including the data link layer.
| FactSnippet No. 1,200,666 |
6.
Ethernet port is widely used in homes and industry, and interworks well with wireless Wi-Fi technologies.
| FactSnippet No. 1,200,667 |
8.
Ethernet port initially competed with Token Ring and other proprietary protocols.
| FactSnippet No. 1,200,669 |
9.
Ethernet port was able to adapt to market needs and with 10BASE2, shift to inexpensive thin coaxial cable and from 1990, to the now-ubiquitous twisted pair with 10BASE-T.

11.
Since then, Ethernet port technology has evolved to meet new bandwidth and market requirements.
| FactSnippet No. 1,200,672 |
12.
Ethernet port has evolved to include higher bandwidth, improved medium access control methods, and different physical media.
| FactSnippet No. 1,200,673 |
13.
Ethernet port establishes link-level connections, which can be defined using both the destination and source addresses.
| FactSnippet No. 1,200,674 |
14.
Ethernet port frames are said to be self-identifying, because of the EtherType field.
| FactSnippet No. 1,200,675 |
15.
Ethernet port was originally based on the idea of computers communicating over a shared coaxial cable acting as a broadcast transmission medium.
| FactSnippet No. 1,200,676 |
16.
Original Ethernet port's shared coaxial cable traversed a building or campus to every attached machine.
| FactSnippet No. 1,200,677 |
17.
Bandwidth advantages, the improved isolation of devices from each other, the ability to easily mix different speeds of devices and the elimination of the chaining limits inherent in non-switched Ethernet port have made switched Ethernet port the dominant network technology.
| FactSnippet No. 1,200,678 |
18.
Advanced networking features ensure Ethernet port security, provide protection features such as MAC lockdown and broadcast radiation filtering, use VLANs to keep different classes of users separate while using the same physical infrastructure, employ multilayer switching to route between different classes, and use link aggregation to add bandwidth to overloaded links and to provide some redundancy.

19.
In 2016, Ethernet port replaced InfiniBand as the most popular system interconnect of TOP500 supercomputers.
| FactSnippet No. 1,200,680 |
20.
Fiber optic variants of Ethernet port are very popular in larger networks, offering high performance, better electrical isolation and longer distance .

21.
Notably, Ethernet port packets have no time-to-live field, leading to possible problems in the presence of a switching loop.
