# IP - is responsible for moving packet of data from node to
node. IP forwards each packet based on a four byte
destination address (the IP number). The Internet
authorities assign ranges of numbers to different
organizations. The organizations assign groups of their
numbers to departments. IP operates on gateway machines that
move data from department to organization to region and then
around the world.
# TCP - is responsible for verifying the correct delivery of
data from client to server. Data can be lost in the
intermediate network. TCP adds support to detect errors or
lost data and to trigger retransmission until the data is
correctly and completely received.
