Use this at your own risk.
I'm not responsible for
what you do with it.
Happy cheating ^^

===========================================================================
What is one advantage of defining network communication by the seven layers of the OSI model?
It increases the bandwidth of a network.
It makes networking easier to learn and understand.
It eliminates many protocol restrictions.
It increases the throughput of a network.
It reduces the need for testing network connectivity.
