codec

Definition

A magical piece of software or hardware that compresses video files so they don't take up your entire hard drive, then decompresses them so you can actually watch the cat videos you hoarded. Short for 'coder-decoder,' it's why your 4K movie doesn't require a forklift to transport. The reason video conferences are possible and also the reason they look terrible when your internet hiccups.

Example Usage

The video wouldn't play because nobody had the right codec installed, leading to the age-old IT question: 'Did you try installing VLC?'

back-end

The behind-the-scenes machinery of websites and apps that users never see but would definitely notice if it stopped working—like stagehands in black running a Broadway show. While the front-end gets all the glory with its pretty buttons and animations, the back-end is busy doing the actual work: processing data, managing databases, and keeping everything from exploding. It's where the real magic happens, assuming you think database queries and server logic are magical.
