The Internet has grown to become the most popular medium used for communication and sharing information. It is a network of computers that are connected to each other, allowing sharing of information. Nothing has connected and brought people together on a common platform the way the Internet has. It has turned out to be one of the most important inventions in the history of mankind, and has become a way of life for many people around the world. Most people have become used to relying totally on the Internet for almost everything they wish to do, whether in their personal or professional lives.

But what happens if we don’t have the Internet. We could not communicate through other people that are far from us and when they are unreachable. Without Internet we couldn’t have Entertainment, we humans need entertainment for us to relieve stress and enjoying our lives to the fullest. If the Internet became non-existent, a long-term global recession will result into millions of people losing their jobs and many businesses closing down. The economy would shrink and be limited to local merchants and stores. For many industries, it might no longer be feasible to do business outside the city or country. Without Internet we couldn’t express our feelings, status, emotions, thoughts to someone or somebody, like using Facebook, Twitter, Instagram, Snapchat and other social media.

There are good and bad sides to virtually everything but I believe the advantages of the internet definitely outweighs its disadvantages. Billions of people are benefited from it each day whether for work or pleasure. So, enjoy living in the paradise we call the Internet, and keep your fingers crossed, as the future brings to us many more Internet technologies and innovations that will totally alter the way we think, act, and live our lives!

The Internet is a vast network that allows the computers in the world to communicate and share information, huge amounts of information in the form of words, images, sounds, and computer software are transmitted through the internet. The internet links computers mainly by the telephone system through copper wires, optical fiber, cables, or radio waves. Access to the Internet begins with the computer link to the telephone lines through a device called a Modem. Special software’s needed to convert computer files into the type of signals that can travel through telephone wires and signals then launched into the phone lines through the modem. The phone lines lead to an Internet Service Provider or a Commercial Online Service which acts as a conduit to the Internet. Computers break the message up into Packets, clusters of 40 to around 1500 characters. Each packet individually mark with its destination is then sent to a series of computers called Routers that directs the path of the packet. Each router examines the packet to see where it’s headed and sends it along the best path to its destination. Packets from the same message may take different routes to reach the same destination. The packets will eventually arrive at the same place and the packets will form again into its original message.

Data packets

When information is being sent from one computer to another it is broken down into small bits of data called 'packets'. Each packet includes information about where the data is going to, where it is from and how to reassemble it.

IP address

Computers use an IP address (Internet Protocol address) to identify each other. It's a bit like a postcode that is unique to each computer connected to the internet. An IP address is a set of numbers that might look like this: 195.188.87.10.

Switch

A smart device that connects together many different devices so they can act as a network. Sometimes simpler devices called 'hubs' are used.

Router

A smart device that directs or routes information around the internet. When a data packet arrives the router reads the IP address information and sends the packet along the best route to its destination.

DNS

The DNS (Domain Name System) is a set of standards for how computers exchange data on the Internet. The DNS turns a user-friendly domain names like bbc.co.uk into an Internet Protocol (IP) address.
