IP is a secret protocol shared between the sender and receiver.

Each network on the Internet uses its own protocol to address messages.

Each device or computer on the Internet is assigned a unique IP address.

IP is the shared way that all devices and computers label their messages with the sender and receiver's addresses.

In order to communicate two devices on the Internet must have the same IP address.

The mailman would sometimes take a different path to deliver each letter to your home.

Letters would be written on the outside of the envelope for all to read instead of letters put inside envelopes.

Your mail could not be delivered if a road your mailman was planning to take were under construction.

One mailman would be responsible for delivering a letter from sender to receiver.

The first 4 bits of the address specify the router number that your friend is on.

Messages are routed over different paths.

You set the "other router" bit in the message.

Everyone is on the same router.

Information does not travel in one piece, but rather as a datastream of packets.

If a single packet is dropped, the entire file must be resent.

Because of the reliability of the Internet, packets always arrive in the same order they were sent.

Information flows on a dedicated direct connection from the sender's device to the receiver's device using binary electrical signals.

A packet contains addressing information to allow routers to decide how best to forward along that packet towards its destination.

A packet travelling between two computers on the Internet may be rerouted many times along the way.

There is one router which receives and redirects all the traffic of the Internet.

Your router receives all the traffic of the Internet and delivers to your computer only the messages intended for you.

Information travelling between two computers over the Internet will always take the same path.

A single direct connection is established between any two devices connected to the Internet.

Both devices are directly connected to at least one part of the Internet.

Both devices are using the same shared and open protocols.

The data of the image is routed through a sequence of directly connected devices before arriving at its destination.

It is possible that the data travels through any of the devices in the network before arriving at device E.

If the data travels through Device D then it will not travel through Device B.

Correct Answer

The data will never be sent to Device G since there are other shorter paths available.

The data will always travel through Device B as it is the shortest path.
