Internet 
BY BRYCE JOHNSTONE
What exactly does the internet mean? 
The Internet is a global system of interconnected computer 
networks that use the standard Internet protocol suite (TCP/IP) to 
link several billion devices worldwide. It is an international network of 
networks that consists of millions of private, public, academic, 
business, and government packet switched networks, linked by a 
broad array of electronic, wireless, and optical networking 
technologies. The Internet carries an extensive range of information 
resources and services, such as the inter-linked hypertext documents 
and applications of the World Wide Web (WWW), 
the infrastructure to support email, and peer-to-peer networks 
for file sharing and telephony. More than 100 countries are linked 
into exchanges of data, news and opinions. According to Internet 
World Stats, as of December 31, 2011 there was an estimated 
2,267,233,742 Internet users worldwide. The number of Internet users 
represents 32.7 percent of the world's population.
Link between the IP address & Domain 
Name 
The IP address and domain name are two different identities, but their roles are same 
to the world. They are connected and supporting each other, the IP address needs the 
domain name to function properly. So does to domain name, it cannot go online 
without connecting to IP address.
What’s a Data 
packet? 
What’s 
packet 
switching? 
A packet is a basic unit of 
communication over a digital network. A 
packet is also called a datagram, a 
segment, a block, a cell or a frame, 
depending on the protocol. When data 
has to be transmitted, it is broken down 
into similar structures of data, which are 
reassembled to the original data chunk 
once they reach their destination. 
Packet switching is where protocols in which messages 
are divided into packets before they are sent. Each 
packet is then transmitted individually and can even 
follow different routes to its destination. Once all the 
packets forming a message arrive at the destination, 
they are recompiled into the original message.
Function of a router 
The routers determine where to send information from one computer to another. 
Routers are specialized computers that send your messages and those of every other 
Internet user speeding to their destinations along thousands of pathways.
