Electrum Transaction Preview Questions (Input & Output)

When previewing a transaction on Electrum, we are given two pieces of information that I cannot find any information on. There is a bit listing “Inputs”, and one listing “Outputs”. The public key of the address being sent money is in the Outputs. Then there is an unfamiliar address in the input, and output section.

Can someone tell me what these are? Are they Electrum’s own addresses from which they make the transactions?
