(b) Parallel virtual machine is a distributed computing system developed by joining a set of parallel computers

(c) Parallel virtual machine is a centralised computing system developed by joining a set of parallel computers

(d) Parallel virtual machine is a distributed computing system developed by joining a set of serial computers

Answer 1

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.
