A computon is a combined unit of computing power, including processor cycles, memory, disk storage and bandwidth. The term was proposed in 2005 by researchers at Hewlett Packard, with the word being a cross between "computation" and "photon", the name for a packet of electromagnetic energy. HP hopes that the computon will become the computing industry's equivalent to public utility's watt-hour.
