DARPA's objective was to:
explore the Internet in science labs around the world
connect supercomputers are universities
develop protocols
see how they could connect together different packet networks
TCP/IP is:

The Internet works by:
moving your emails around the network in one big packet
breaking the information you want to communicate into very small parts
routing packets to avoid problems
unique IP addresses
A packet can contain up to 1,500:
IP addresses
loads
bytes
emails
Which information does a packet NOT contain?
where it came from
what language it is in
where it is going
how many packets the email has been broken into
An IP address is:
another word for packet

composed of between 1,000 and 1,500 bytes
a unique string of numbers that identifies a computer on a network
To ensure that all parts of your message arrives, the Internet uses:
packet switching
load balancing
IP addresses
return receipts
