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.
Wind observations are taken at a fixed location using two parameters: wind speed and wind direction. Referenced with respect to true North, the direction that the wind is flowing from is measured in degrees. It also described by the compass points its flowing from (N, NE, NNE, etc.). Wind speed is a measurement of the speed of movement of the air, and is typically reported in miles per hour (mph) or kilometers per hour (kph). Reports for maritime and aeronautical operations may use those or knots (nautical miles per hour). Wind speed and wind direction can be measured with a variety of tools. The most common is the anemometer, which typically consists of a rotating vane to measure direction and a shaft with cups attached that spins with the wind to measure its speed.
