It stands for Direct Current. There is AC or Alternating Current which is what you have in the home. The receptacle is for a Wallwart or external power supply that converts 120 Volts AC to 4.5 Volt DC. Hope this answers your question.

If you buy a AC adapter, make sure it has the correct polarity and the necesary amps. The diamnds with the circle in the middle that may exist next to the 4.5 v sign shows the polarity. Most devices accept positive polarity in the middle and negative at the rim.
