We would like to understand the names that can be assigned for 
routers and how they are used and the importance of each.
We have read alot of posts and all the config information, but
we  still have not quit understood what the function of each is ?
What is the purpose of the following, if you have a moment and
have a good understanding of their uses.
Internet
Host name :  DIR-615   
                                             
Wireless

Thank You so very much
