thin client
Alternative to desktop PC's. Often with no moving parts (eg hard drive, fans) - low power in terms of processor speed and electrical consumption. Relies on server infrastructure to run applications and process data. In fact, these products come in a range of thin-ness from thin to tubby - depending on how reduced the processing and storage capability is compared to a "fat" PC. Extreme thin clients are sometimes called "Zero Clients" - and may have extremely low power consumption (say 4 Watts) - and can even be designed within a form factor which resides within an enclosure resembling an electrical wall socket but with keyboard, screen and mouse connectors in the place of a mains connector.
