Communication Between Two Hosts
When two hosts wish to communicate, they must roughly follow these steps
 * 1) Host A breaks up message into chunks and attach header bytes to them which creates packets
 * 2) Host A sends off these packets to his local ISP through the TCP/IP
 * 3) Host B receives all of the packets and reassembles them into the original message
