RJ-45, RJ-11, RJ-22 connectors

Three major modular connector types used in Telecommunications and computer networking.
The RJ-45 (formally referred to as "8P8C" or "8 pin, 8 Conductor") is the most common type used for Ethernet cabling.
The RJ-11 is the standard for telephone connections between the desk instrument (the phone) and the wall jack.
The Rj-22 is lesser know, but is often confused with the RJ-11. The RJ-22 is mainly just used on the curly cord that connects the hand piece to the phone base.

You videos are very helpful, thank you for sharing your knowledge.

There is a connector not usually seen in networking. It is the 10 pin connector. It is an RJ48 and has 10 pins rather than the 8 pins found on RJ45. It would be understandable for most people to not know that it exists. What are they used for anyhow? I think T1 lines and other things like that.
