The document provides an overview of the internet and how it functions. It discusses what the internet is, how domain names and IP addresses direct users to websites, how data is broken into packets and sent via packet switching through routers to reach its destination, and references for further information. The internet is a worldwide system that allows sharing of information, images, and social connections between over 2 billion users globally. Data is transmitted between computers by being broken into packets and sent individually through routers then reassembled at its destination.

4. DOMAIN NAMES AND IP ADDRESSES
A domain name is the website address such as google.com or Hotmail.com
A domain name uses words and letters rather than numbers
A domain name is something that is specific to a certain website
An IP address is an individual set of numbers which send you to a website. These numbers are usually separated by dots.
A domain name and an IP address are the same thing yet domain names are used more since they are easier to remember.
By typing in a domain name into the search bar, your computer will then change it into it’s IP address and direct you to your desired website.

5. DATA PACKETS AND PACKET SWITCHING
A data packet is used over a network as a form of digital communication.
Data packets are used when information has to be sent. It is broke down, transmitted and then reassembles once the data has been sent.
Packet switching is a mode of sending data in a message. Although, this message is broken down into smaller parts and sent individually.
The data is then put back together. Data packets and packet switching is very similar.

6. ROUTERS
A router is where all of the data is sent in a computer.
Data from a device is sent to the router in order to be in it’s desired place.
The router directs the data to where it is supposed to be.
The router organises the data so that the computer can function correctly.
