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.
Calibrated airspeed (CAS) is the IAS corrected for instrument and position error . An aircraft's indicated airspeed in knots is typically abbreviated KIAS for  Knots -Indicated Air Speed (vs. KCAS for calibrated airspeed and KTAS for true airspeed ). The IAS is an imp Express yourself. Organize your knowledge. Expand your mind. Discover the world.
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.
