ARQ is an acronym for Automatic Repeat reQuest. A function of a modem that enables it to detect flawed data and request that it be retransmitted.

ARQ is also short for advanced RISC computing, a reduced instruction set computer (RISC) based computer architecture standard, associated with the ACE consortium. The Advanced RISC Computing Specification (ARC Spec) defines the architecture for an industry standard computing platform based on the MIPS family of microprocessors.
