[dba-Tech] Wireless Terminology Question

Hi All,

What is the difference between a wireless router and a wireless access 
point?  I'm reading up on the "how to" of installing wireless networks.  
I have one little one that I cobbled together by hit and miss tactics, 
but now I would like to know what I am really supposed to be doing.  The 
page at http://www.microsoft.com/athome/moredone/wirelesssetup.mspx says 
to be sure to get a wireless router not a wireless access point.  I know 
I have a router - it says so right on the box.  But I don't know the 
difference between the two things.  Thanks for any wisdom you care to share.
