A powerpoint that hopefully provides some useful information on aspects of the Internet. Enjoy :)

1. PACKETS, ROUTERS, AND IP ADDRESSES
“The Internet is a global computer network providing a
variety of information and communication facilities,
consisting of interconnected networks using
standardized communication protocols.”

2. DOMAIN NAMES AND IP ADDRESSES
 Are you confused about the relationship (and difference)
between domain names and IP addresses? You’re not
alone.
 If you’re familiar with the internet at all, which you likely
are since you are on this site, you’ve no doubt seen a
domain name before. It’s the address at the top of this
page, in the URL bar. After the prefix (http://www.) of any
website, you’ll find the domain name associated with
that website. An IP Address, however, is a loooong
string of numbers, unique to every website.

3. HOW DO DOMAIN NAMES AND IP ADDRESSES
RELATE?
 Well, it wouldn’t really do to type in a long string of
numbers when you want to visit your favourite blogs,
read the news, or find out about the weekend weather
forecast, so domain names are used as more user-friendly
cousins of IP addresses where websites are
stored.
 So, for example, say you have a website. You therefore
will find out the IP address for the server where you’re
storing your files. It might be formatted something like
this: xxx.xx.xxx.xxx.
 No one wants to type that into a URL bar, so you do a
domain name search to find the perfect domain name
for your site, so that when people type in your domain
name, they’ll be taken to your site.

4. DATA PACKETS
 A data packet is a unit of data made into a single
package that travels along a given network path.
Data packets are used in Internet Protocol (IP)
transmissions for data that navigates the Web, and
in other kinds of networks.

5. PACKET SWITCHING
 Packet switching is a digital network transportation
process in which data is broken into suitably-sized
pieces or blocks for fast and efficient transfer via
different network devices. When a computer
attempts to send a file to another computer, the file
is broken into packets so that it can be sent across
the network in the most efficient way.

6. ROUTERS
 A router is a computer networking device that
determines the next network point to which a data
packet should be forwarded toward its destination,
a process known as routing.

Considerable
amounts of
further research
were needed.
Helped create a more
detailed understanding,
a small amount of
further research was
needed.
