10.6 The World Wide Web
The Internet was growing as more and more networks were being joined together. However it was only being used by the military and academics due to it's compliexity.
In 1990 an Englishman known as Dr Tim Berners-Lee developed a simple document formatting language called 'HTML' which enabled documents to be stored on the fledgling Internet and to link to other documents using 'Hyperlinks'. He also developed an application to read these documents called a 'Browser'.
Due to the simplicity and huge scope of these inventions there are billions of websites all around the World written by anybody with a connection to the Internet.
The linking of these websites to other websites means there is a web of links spanning the globe. This is known as the World Wide Web.

10.6 The Internet
The start of the network which is now known as The Internet was first developed in the 1950's by the US Defence.
It wanted to be able to link their missile bases around the US to be able to strike back at anybody that fired missiles at them. They wanted to remove any possibility of problems so built in 'redundancy'. They created a 'mesh network'.
Other countries around the World developed similar national networks and when IBM linked the US to the UK via a trans-Atlantic cable called FatPipe in the early 1980's, the International Network was born - the Internet.

10.6 The Role of Communication Systems
If you wanted to send the entire Encyclopedia Britanica to your Aunty in Australia, you wouldn't send it by SMS (text message). You probably wouldn't email it either. These communications systems are useful for specific reasons but are limited.
In this particular instance you would probably blow it onto a DVD and send it by snail mail.
The choice of communication system is dependent upon several things:

The choice of communication system is dependent upon several things:

When deciding upon what communication device is best for a particular scenerio, think about these 6 areas.
