Differences between RJ-11 and RJ-45:

• RJ-11 (connectors) have positions for 6 wires (3 pairs), used primarily used for voice transmission over typically 2 ranging up to 6 of the wires.

• RJ-45 has 8 wires (4 twisted pairs), primarily used for data transmission over 4 to 8 wires.

• Connectors are physically different sizes.

That said, they have many similarities as well. Some you may not have thought of:

• RJ-11 and RJ-45 both have pin spacing that is identical. This is by design.

• RJ-11 and RJ-45 both have connectors of identical height.

• RJ-11 and RJ-45 both use the same shape and size centralized plastic locking pin.

Thus, the only sfdifference being RJ-45 allows for 2 extra pins and is a slight bit wider. So In a pinch, an RJ-11/14 6 wire cable can be used to connect two RJ-45 devices provided that that RJ-11 cable has all four or six wires and the RJ-45 socketed devices are only 10 or 100-base-T (sub gigabit) devices as they only use 4 wires. Gigabit devices require use of all 8 wires so it doesn't work for 1000-base-T devices. Also, if the RJ-11 cable is flat-wire (not twisted pair UTP) then the run will have to be very short due to noise considerations. This makes it harder to achieve full speed on 100 Megabit class connections.

what is the name of the jack the CAT 5 plugs into?

The form factor is RJ-45. However, RJ-45 is not necessarily CAT-5; many RJ-45 jacks are intended for phone use and only spec to CAT3 or even less. Typically, the jack that CAT5 plugs into is called a CAT5 jack, to differentiate it from the CAT3 RJ-45.
