    Crisp, clear “difference”.
    Perhaps it would have been better if:
    “Although you can plug an RJ11 connector into an RJ45 slot, you should avoid doing that …”
    was
    “Although you can ^physically^ plug an RJ11 connector into an RJ45 slot, you should avoid doing that…”

    Yes, great explanation.

    I have one question for clarification about damage to a device that has an RJ45 slot by plugging in an RJ11 connected to a phone line. Wouldn’t that only be true if, as you mention, the telephone company is supplying power in it’s lines that will keep your phone working in a power outage? Wouldn’t it be safe to run both RJ45 (e.g. ethernet) and your phone through the same RJ45 slot if you have a digitized phone line such as Verizon FIOS service rather than the old fashioned analog phone service powered by a telephone company central office?

    “Although you can plug an RJ11 connector into an RJ45 slot, you should avoid doing that because you might damage the device that has the RJ45 slot, whether it is a switch or a network adapter. This is true when you use an RJ11 connector that is connected to your phone line. The reason behind this is the power that is being delivered by the telephone company into your handset that allows it to function even during a power outage.
