Of course there is.  The advantage of a 20 amp (120 volt) socket is that
it can take either the standard NEMA 5-15P plug (the normal standard 15
amp plug we are all familiar with) and the NEMA 5-20P (the 20 amp
version).  That allows you to plug a 15 amp device into either a 15 or
20 amp 110 volt socket.  But you can't plug a 20 amp device into a 15
amp socket.

Here's a link to some images of plugs/sockets:
