The internet is a worldwide network of interconnected computers that allows for the sharing of information. Domain names provide easy-to-remember addresses for websites, while IP addresses are the actual numeric identifiers for computers on the network. Data is broken into packets when sent over the internet and reassembled at its destination to help ensure efficient transmission. Routers are specialized computers that determine the best path for data packets to travel and help prevent network congestion.

1. THE INTERNET

2. DEFINITION OF THE INTERNET
The internet is a worldwide network on
computers which can provide
information and communication of all
sorts. It uses interconnected networks.

3. DOMAIN NAMES AND IP ADDRESSES
Domain names
 The domain name is
the part of a network
address that tells you
which domain it is
from. A domain is a
particular territory
controlled by a ruler.
IP addresses
An IP address is a way
to identify a computer.
It consists of a line of
individual numbers
separated by full
stops.
Domain addresses are what people type in their web
browser to find your website and the that finds the real
address that contains the website. The real address is the IP
address. They are both linked because they both help find
the website

4. DATA PACKETS AND PACKET SWITCHING
 A data packet is a unit of data carried by a packet -
switched network
A data packet is a basic type of communication over
a network. When data is transmitted it is broke down
into smaller pieces and then reassembled when it
reaches the other side.

5. ROUTERS
An internet determines where to send information
from one computer to another computer. Routers are
specialised computers that send your messages
directly and quickly to their destination. A router has
two jobs:
 It ensures that information doesn't go where it's not
supposed to. This is important so the internet does not
get clogged up.
 It makes sure that information makes it to the intended
destination.
