In tech, “boxen” is an informal pluralization of “box,” which itself is slang for a computer, server, or other computing hardware. While the standard English plural would be “boxes,” some tech professionals playfully use “boxen” instead, following a mock Germanic pluralization pattern.
The term is most commonly heard in system administration contexts when referring to multiple computer systems or servers, as in “We need to update all the boxen in the data center.”
It’s primarily used in casual technical conversation and not in formal documentation or official communication.
