The “internet” is the system of data connections between different networks of computers; it can support a variety of protocols for sharing data between computers, allowing activities such as email and FTP. The “world wide web” is a system of linked documents (“web pages”) accessed via the internet with a web browser.

I started using the internet on a regular basis in 1994 while at university. We had workstations that used an early web browser called NCSA Mosaic. The number of web pages in existence at that time could be counted in the thousands. I setup my own website on the university’s servers in 1995.

The utility of the world wide web has been growing exponentially over the past 10 years to the point where many people like me can now think of it as a modern-day oracle.

This week I bought a second-hand car. Sure, I found it on the WWW at autotrader.co.uk. That itself is not surprising. It is a 1999 Ford Focus.

When I collected the vehicle, I found that the heating system was not working properly. The fan has 4 speed settings. On 1 and 2 there was no fan action at all. It would only work on 3 and 4.

Rather than taking a day off work and taking the car to a garage and paying hundreds of pounds on labour, I Googled for a solution.

After spending a little while reading through a number of forum posts, I realised that this was a common problem with the Ford Focus. More importantly, it was really easy to fix - this forum post gave detailed instructions including photos.

Now the heating system and fan works perfectly, and I have saved myself a lot of money and hassle.

In the past, people and societies used to consult oracles for answers to their problems. These days we have the WWW which is fulfilling a similar function.
