10.4.1 Drivers of e-commerce and Internet growth

Reading 2

View links on the Internet’s history and growth at the Internet Society: http://www.isoc.org/Internet/history/ and read the Brief History of the Internet at http://www.isoc.org/Internet/history/brief.shtml

You should also refer to and examine a timeline of the development of the Internet, see Hobbes' Internet Timeline at http://www.zakon.org/robert/Internet/timeline/

Activity 3

Consider the information presented with the readings listed under Reading 2 Now respond to the following.

  1. Reflect on the fact that the Internet and e-commerce use of this medium has only really been available to the public since 1991/92.
  2. Would you consider the Internet a new technology or a well developed technology?
  3. What is the distinction between the Internet and the World Wide Web?
  4. In what ways is the Internet still evolving?

A lot of computer networking activity developed from Robert Metcalfe’s invention of the Ethernet protocol for computer networks. He also identified that the value or power of a network increases in proportion to the square of the number of nodes on a network. This is known as Metcalfe’s Law, and it suggests that, for example, the more people who own a phone, fax or are connected to a computer network, the more useful it is for people to have a phone, fax or be connected to a computer network.

This is reflected in the following comments from Marc Andreesen, one of the founders of the web :

A network in general behaves in such a way that [as] more nodes … are added to it, the whole thing gets more valuable for everyone on it because all of a sudden there's all this new stuff that wasn't there before. You saw it with the phone system. The more phones that are on the network, the more valuable it is to everyone because then you can call these people. Federal Express, in order to grow their business, would add a node in Topeka and business in New York would spike. You see it on the Internet all the time. Every new node, every new server, every new user expands the possibilities for everyone else who's already there.

This effect has been driving the growth of the Internet for several decades. Its growth appeared to particularly accelerate with the emergence of the World Wide Web (aka WWW or the Web. Briefly, the Web is a use of the Internet much as a word processor is a use of a computer and operating system. This will be covered in more detail in the next chapter). The Web was developed and released by Tim Berners-Lee of CERN, which is the European Organisation for Nuclear Research. CERN explain the origins and significance of the web as follows:

In late 1990, Tim Berners-Lee, a scientist at CERN, invented the World Wide Web …The Web, as it is affectionately called, was originally conceived and developed to meet the demand for automatic information sharing between scientists working in different universities and institutes all over the world.

The basic idea of WWW was to merge the technologies of personal computers, computer networking and hypertext into a powerful and easy to use global information system.

Hypertext is text with links to further information, on the model of references in a scientific paper or cross-references in a dictionary. With electronic documents, these cross-references can be followed by a mouse-click, and with the World-Wide Web, they can be anywhere in the world. There is no need to know where the information is stored, and no need to know any detail on how it is formatted or organized.

‘Wandering from one document (webpage) to another’ is called browsing. Some people do this just for fun, following links just to see what's there. This is usually called ‘surfing the Web’.

Of course, behind this apparent simplicity there is a set of ingenious design concepts, protocols and conventions.

Nowadays, the WWW has expanded from its original scientific environment and has millions of academic and commercial users. CERN, 2004

Apart from the effects described by Metcalfe’s Law, technology has become cheaper and more powerful over time, allowing more data to be created, processed, stored and communicated via networks.
