Source: Sleep Talking Mode To Save Energy
Sleep Mode - which goes under the name standby, sleep or suspend depending on the operating system in use - has been created to save energy in situations where a computer system does not perform any active calculations. The operating system will power down most of the connected hardware devices except for the computer memory which is being used to restore the previous state once the computer ends sleep mode. The unresponsiveness of computer systems that are in sleep mode made it impracticable for certain situations where response is required. This includes staying connected to a computer network, being available in Instant Messengers and VOIP software or availability for remote access
