Answer» The correct choice is (b) Parallel virtual MACHINE is a distributed computing SYSTEM developed by joining a set of parallel computers Easy explanation: A parallel virtual machine is a distributed computing system developed by joining a set of parallel computers into a single virtual machine. Complex COMPUTATIONAL problems MAY be solved more efficiently by utilizing collective power and memory of many computers. It may be used for RESOURCE allocation in cognitive radio.
