â¢ In hibernation, the computer completely turns off while, on standby (or sleep mode), computer is at a minimal power consuming state where the memory elements are consuming power. â¢ In hibernation, an image of the memory is saved to the hard drive while, on standby, the memory is retained.
Indicated airspeed (IAS) is the airspeed read directly from the airspeed indicator (ASI) on an aircraft, driven by the pitot-static system . It uses the difference between total pressure and static pressure, provided by that system, to either mechanically or electronically measure dynamic pressure.
Speed is a scalar (dimensionless) quantity, while velocity is a vector quantity consisting of speed and direction. We might say a car is traveling at 20 m/s, and this tells us its speed. Or we might say the car is traveling at 20 m/s at a compass bearing of 25 degrees (north-by-northeast); this tells us its velocity.
