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

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.
