It assigns a unique address to every device on the Internet.

It returns the IP address given the name of a website.

It forwards a message from one machine to another.

It has more bits so you can make a longer, unique address.

IP v6 is easier to use.

IP v4 does not work on old hardware.

IP v4 was not encrypted.

We are running out of IP v4 addresses.

Packets are numbered so they can be reordered when received.

Packets are routed on different paths from sender to receiver.

A message can be contained in one single packet.

The receiver must confirm that the message has been received.

Protocols ensure that a single path between two computers is established before sending packets over it.

Routers are hierarchical and the "root" router is responsible for communicating to sub-routers the best paths for them to route internet traffic.

A packet traveling between two computers on the Internet may be rerouted many times along the way or even lost or "dropped".

Routers act independently and route packets as they see fit.

Packets are numbered so if they arrive out of order the message can be reassembled.

TCP guarantees that no packets are ever dropped

Packets can be routed on different paths from sender to receiver.

Messages are broken into packets to improve reliability of the internet

data compression algorithm that allows the original data to be perfectly reconstructed from different compressed data.

Irreversible compression - a data compression method that uses inexact approximations, discarding some data to represent the content.

Backwards compression - a data compression that restores data backwards.
