What is end-to-end encryption?

Much of the encryption that is performed online is so-called end-to-end encryption. End-to-end encryption means encryption and decryption are performed at the ends of the connection: on the client and server, or on both peers of a peer-to-peer connection. This is in contrast to link-layer encryption, where encryption is potentially performed only on one part of a connection-​such as a wireless link.

Also, you only said what end to end DOES, the title of the video claims you were about to explain HOW it does it. I want my 4 minutes of life back.
