Wiring a Wall Type RJ45 Jack
See also: PCI-E. Supposedly, at insane data rates (real circuit bandwidth 1GHz), even if signal quality can be managed, propagation skew between bus lines is ever more difficult (have you seen all the squiggles on a motherboard between processor, northbridge and RAM?). So why not skip bus width altogether, crank the clock rate (pushing circuit bandwidth even more though), and use multiple asynchronous channels. The advantage lies in clocking each stream at its own rate, rather than clocking 32 or 64 bits at an identical rate. Bytes could arrive out-of-order, but buffering done on-chip is a lot faster than a maze of wires on-board. Tim I've got no argument with what you're saying. There's are newer bus technologies in the works but until a serialized processor comes out, what's the point of switching to serial peripherals? If the processor is outputting parallel data lines and has to be addressed in the same way, why not deal with the race conditions of the parallel busses? I'm having a major headache right now trying to adapt an LG Electronics optical drive to an older Intel ICH4 SATA controller. IMHO, Intel released the controller long before it was workable. Even the next generation, ICH5, was limited in structure. It allowed for 2 PATA controllers and a SATA controller with the provision that all could not be used together. Intel did not make them BIOS selectable because they knew certain combinations could be disasterous. So they left the configuration up to the OS manufacturer. Thanks!! Now I can't get information from Intel, Silicon Image, Microsoft or LG Electronics. They dump this crap on you with the spin that they are new technology and will improve things. When I heard that about twisted-pair technology, I nearly crapped. People bought into it, some thinking twisted pair had suddenly become superior to coax, just because they twisted it better. Anyone believing that has a serious issue with technological understanding, like the fatbytestard. |

Wiring a Wall Type RJ45 Jack
This 'reflects' proper avenues as clock rates climb (a little data transfer joke there). Definitely the right way. Managing little capture buffers is far better than managing errant data. I'll bet that serial allows one to downsize error correction overhead as well... or could/should anyway. **** off you dumb ****. You use a lot of words without having the vaguest sense of what they mean. |

Running light weight, cheap twisted pair is a LOT cheaper than running coax was, and coax topped out at 2Mb/s back then as it was ABANDONED by the ETHERNET standard, and was a hell of a lot harder to make the drops for. 10base2 was about 5 times faster than that over RG58A/U coax. perhaps you are thinking of arcnet. |

No, you said coax Ethernet "topped out at 2Mb/s." 10base2 is (thin) coax Ethernet running 10Mb/s. As Jasen said, "5 times faster" than what you said. 10base Ethernet is 10Mb/s whether it's twisted pair (-T) or coax (2 or 5) or fiber (-FL). That's what the "10" means. Except that the coax implementations were tied to the cards they were attached to and those were 2Mb/s. By the time the 10Mb/s stuff hit the streets, folks were buying twisted pair solutions, and coax was practically completely abandoned. The card makers stopped putting coax I/O ports on the cards, and rj45 became all you could get, Ethernet wise. TCNS and MS had some proprietary protocol Star configurations, and there were a few others, but Ethernet ended up winning because it kept up speed wise, and was considerably cheaper. Now, I don't even know if any other methods exist, except for fiber, of course. What other wired solutions are there currently? |

Maybe whatever the heck you had was 2Mb/s but my Ethernet cards were 10Mb/s and I've still got the cards, cable, and T connectors around here somewhere but it's been so long I don't recall where that 'old parts' box ended up.

The card makers stopped putting coax I/O ports on the cards, and rj45 became all you could get, Ethernet wise. The 10Mb/s cards with both coax and RJ45 connectors I can still find because some are in the PCI 'old parts' box. Coax connectors on the cards ended with 100Mb/s I still have a 4 computer network running with 10base ethernet on coax, ending at a NetGear Etherhub, to connect to my router(Speedtouch). And the speed is 10 Megabyte/sec, or 100Megabit/second, which it achieves without a problem. |

"Cheapernet" used the same card, but the comm protocols meant that you would only see about 2, and that only on a good day.

The 10Mb/s cards with both coax and RJ45 connectors I can still find because some are in the PCI 'old parts' box. Yes, and the RJ45 DOES do 10Mb/s, but the coax does NOT. Coax connectors on the cards ended with 100Mb/s Not in Ethernet. TCNS and a couple other proprietary bits of hardware made it out, but Ethernet was twisted pair only by the time is was actually able to push the 10Mb/s streams it touted itself as being able to push. The coax never did from my memory. What other wired solutions are there currently? Not even going to try? |

Ethernet is specified in Mbits/sec. 10-base-anything is 10 Mbits/sec. 10base2 is coax with RG-58A/U connectors. 10base5 is thick coax with vampire taps. 10baseT is Cat5 with RJ-45 connectors. All of the above are 10Mbit/sec. 100baseT is 100Mbit/sec, and uses Cat5 with RJ-45 connectors; there are no coax versions. |

The interface (Ethernet) is declared in BITS per second, and they were NOT EVER 100 Mb/s on 10 base T. Not ever at any time. |
