# Problem Exists Between Computer and Chair (PEBCAC) PEBCAC (also written as PEBKAC — "Problem Exists Between Keyboard and Chair") is tech slang for user error. It describes situations where the root cause of a technical issue is the person using the system, not the system itself. Variants: - **PEBCAC** — Problem Exists Between Computer and Chair - **PEBKAC** — Problem Exists Between Keyboard and Chair - **ID10T error** — "Idiot" error, same concept - **Layer 8 problem** — User layer above the OSI model's 7 layers The term is used (often humorously) among IT professionals and developers to label issues caused by misuse, misunderstanding, or lack of training rather than a genuine software or hardware defect. ## References - ## Related -
