22 Facts About Ethernet cable
2.
Ethernet cable has since been refined to support higher bit rates, a greater number of nodes, and longer link distances, but retains much backward compatibility.

3.
Over time, Ethernet cable has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET.
| FactSnippet No. 1,200,642 |
4.
Original 10BASE5 Ethernet uses coaxial cable as a shared medium, while the newer Ethernet variants use twisted pair and fiber optic links in conjunction with switches.
| FactSnippet No. 1,200,643 |
5.
The Ethernet cable standards include several wiring and signaling variants of the OSI physical layer.
| FactSnippet No. 1,200,644 |
6.
Per the OSI model, Ethernet cable provides services up to and including the data link layer.
| FactSnippet No. 1,200,645 |
7.
Ethernet cable is widely used in homes and industry, and interworks well with wireless Wi-Fi technologies.
| FactSnippet No. 1,200,646 |
9.
Ethernet cable initially competed with Token Ring and other proprietary protocols.
| FactSnippet No. 1,200,648 |
11.
Since then, Ethernet cable technology has evolved to meet new bandwidth and market requirements.
| FactSnippet No. 1,200,650 |
12.
Ethernet cable has evolved to include higher bandwidth, improved medium access control methods, and different physical media.
| FactSnippet No. 1,200,651 |
13.
Ethernet cable establishes link-level connections, which can be defined using both the destination and source addresses.
| FactSnippet No. 1,200,652 |
14.
Ethernet cable frames are said to be self-identifying, because of the EtherType field.
| FactSnippet No. 1,200,653 |
15.
The method used was similar to those used in radio systems, with the common cable providing the communication channel likened to the Luminiferous aether in 19th-century physics, and it was from this reference that the name "Ethernet" was derived.

16.
Original Ethernet's shared coaxial cable traversed a building or campus to every attached machine.
| FactSnippet No. 1,200,655 |
17.
The network interface card interrupts the CPU only when appliEthernet cable packets are received: the card ignores information not addressed to it.
| FactSnippet No. 1,200,656 |
18.
Use of a single Ethernet cable means that the data bandwidth is shared, such that, for example, available data bandwidth to each device is halved when two stations are simultaneously active.
| FactSnippet No. 1,200,657 |
19.
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 cable have made switched Ethernet cable the dominant network technology.
| FactSnippet No. 1,200,658 |
20.
In 2016, Ethernet cable replaced InfiniBand as the most popular system interconnect of TOP500 supercomputers.
| FactSnippet No. 1,200,659 |
21.
Fiber optic variants of Ethernet cable are very popular in larger networks, offering high performance, better electrical isolation and longer distance .
| FactSnippet No. 1,200,660 |
22.
Notably, Ethernet cable packets have no time-to-live field, leading to possible problems in the presence of a switching loop.
