I am learning the basics of windows server 7so please don't flame me:When referring to a network's "medium", the book basics say that it is usually referring to the cabling used in the network infastructure, but my question is does this term (medium) apply to wireless as well? If the network is wireless versus using ethernet, does that mean the word applies to method of transmission or just any kind of physical cabling used?

Hello,Since question is concerning Windows 7,please try the windows 7 networking forum as the expert there might be able to helpIsaac Oben MCITP:EA, MCSE

With a wireless network, the medium is the "ether", or empty space between each tranceiver.Ether is a concept that represents a ficticious medium through which electromagnetic waves travel. When physicists first discovered the wave nature of light, they thought that if there is a wave, there must be a medium. But that was before relativity and quantum theory.Issac, the OP referred to Windows 7 Server, which I have seen Server 2008 R2 refered as in the eta.
