3. explanation of data packets and
packet switching
Packet switching happens when you want
to send a file through the internet such
as an email. Packet switching breaks up
the 5 mb file and splits it up into smaller
files and sends it through many routers
but they all get sent to the same IP
address.

4. Routers.
The internet is made up of many paths
and the paths are used to transmit data,
routers read the paths and find the
quickest route available for your file, it
can also use many different paths for the
same file as it breaks the file up.
