Orthogonal persistence refers to inherent support provided by a programming language or operating system of a computer that enables the state of programs written in a persistent programming language, or of the operating system itself, to remain persistent even after a crash or unexpected shutdown. The computer stays in the same state even if you turn it off, behaving much like a TV or similar device. One operating system that employs this ability is EROS. One programming language that employs this ability is PS-Algol.
