My appologies for a late week post it's been a bit hectic with a friend having surgery (who is now fine), but helping out my friend took priority.  I digress that is not the purpose of this post/  Although one could argue that no matter how often one may want to be alone no one does not have a network.  "Network" was not a common word in the early days of computers but since the 90's they have become more common and more complicated.  Homes can now have as complicated a system as some businesses. 

There are a variety of network capabilities from room to rooom ie a college dorm Lan or Wan.
