Ooh..., tough one. You could say it is the user. But that is lame. You could also say processor, since no computer could work without one. My first computer worked with a 5¼" floppy drive, no hard drive, 256 kb of RAM and a 4.7 Mhz processor. No mouse either. The graphics were CGA and EGA.
It is a vibration dampener. A primary application for the device is to reduce vibrations in pumping systems.
A transformer is the primary device which transforms voltage to a higher or lower voltage. In electronics, capacitors and resistors perform this function.
The primary advantage is that it makes your files smaller. Smaller files do not take up as much room on your storage device as larger files. The primary disadvantage is that you might loose sound quality or fidelity.
Auxiliary contacts are additional contacts used in conjunction with a primary switch or relay to provide additional control or indication functions. They operate in synchronization with the main contacts, either opening or closing alongside them as the primary device is activated or deactivated. These contacts can be normally open (NO) or normally closed (NC) and are commonly used in control circuits to signal the status of the primary device or to control other devices in a system. Their versatility allows for more complex control schemes and automation in electrical systems.
You would need an inverter http://en.wikipedia.org/wiki/Inverter_%28electrical%29
No it's the handset that is a primary device
A primary device would be the main system drive. Almost always a hard drive. A primary storage device might just be another way to refer to it.
