"The CPU" is also a CPU, which is installed onto a piece of plastic (the motherboard PCB); typically CPU works with an electric motor - its cooling fan. Or, by the way, the heatsink, and the computer case as a whole, are also pieces of metal. Should I go down to similarity between screws, voltage regulators, decoupling caps, resistors, etc. ? ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
