Domain Names And IP Addresses A domain name is
a unique name that identifies an internet
resource, an example of this is a website. It is
an identification string that allows a user to
access and view websites, but without memorising
and typing a series of numbers which is called an
IP Address (internet protocol), or memorising the
http address, this provides a much more memorable
alternative, which is just the websites name.

Their link is that the domain name is the name
people would type into their browser to get the
website, this then directs the user to the IP
address which then directs the user to the
location of the files.

Data Packets And Package Switching A data
packet is block of information sent over a
digital network, for example the internet when
data has to be sent it is broken down into
smaller parts and then sent, they are put back
together to the original data chunk once they
reach where they are meant to. For example a 4MB
file would be broken up into chunks 500 bytes in
size.
This is a diagram explaining how data packets
work to go to their location. The data splits,
then goes to the IP address via routers across
the Digital Network
The switching process flows this way

The Function Of A Router A router is a machine
which works out the fastest connection through
the digital network and sends each data packet on
its journey to the desired locations, sometimes
going through hundreds of routers through many,
many countries. If one of these branches gets
broken in anyway, getting broken can mean either
the branch is too busy or the server is down,
and the router redirects the packet down another
branch.
