hi,

a perfect network would be right as you search something it would work in a snap, super protected, no hackers, would have maintenance every week, everyone one would share anything and everything as long as its safe, no viruses or over 18 stuff.communication would be like hangouts, and a network administrators would check what is happening and check if everything is safe.

hope this !
