This power point will tell you all the basics about the internet

1. The Internet
The internet is a global computer network
which provide information across the world, it
consists interconnected networks which use
standardized communication protocols.
Translation from oxford dictionary.

2. The relationship between Domain names
and IP addresses
o The Domain name is the address which you would type into
your web browser to get to whatever website you would like
to. E.g. I would type in vle.brgs.org, to get onto the BRGS
Moodle.
o The IP address is the series of binary code which actually
shows you the main address. It also tells you everything which
you would need to know about the website.
o The Domain name and the IP address may have two different
identities to the world but really they are both the same. Both
of them are connected and are supporting each other, the IP
address needs the Domain name to function properly and the
Domain name needs the IP address or it cannot connect to
the internet.

3. Data Packets & Packet switching
• Data packets are basically just data which is broken into
smaller parts then packaged up and then it is redirected.
Data packets are how most of the data travels over the
internet and it is even used on phones today.
• Packet switching is the same as data packets except this is
how you send them. As usual the data is broken up into small
chunks and then packaged away but it really does depend
on the amount of MB’s and bytes because that decides the
size of the packet.

4. Routers
o Routers are the machines behind it all. They
decide where to send the data packets to
make sure that they get to their destination
but, it has to be done in the most fastest and
cleverest way.
