The Internet: Everything You Need to Know

[ed. A sharp, concise primer for understanding the internet, in nine big themes.]

by John Naughton

A funny thing happened to us on the way to the future. The internet went from being something exotic to being boring utility, like mains electricity or running water – and we never really noticed. So we wound up being totally dependent on a system about which we are terminally incurious. You think I exaggerate about the dependence? Well, just ask Estonia, one of the most internet-dependent countries on the planet, which in 2007 was more or less shut down for two weeks by a sustained attack on its network infrastructure. Or imagine what it would be like if, one day, you suddenly found yourself unable to book flights, transfer funds from your bank account, check bus timetables, send email, search Google, call your family using Skype, buy music from Apple or books from Amazon, buy or sell stuff on eBay, watch clips on YouTube or BBC programmes on the iPlayer – or do the 1,001 other things that have become as natural as breathing.

The internet has quietly infiltrated our lives, and yet we seem to be remarkably unreflective about it. That's not because we're short of information about the network; on the contrary, we're awash with the stuff. It's just that we don't know what it all means. We're in the state once described by that great scholar of cyberspace, Manuel Castells, as "informed bewilderment".

Mainstream media don't exactly help here, because much – if not most – media coverage of the net is negative. It may be essential for our kids' education, they concede, but it's riddled with online predators, seeking children to "groom" for abuse. Google is supposedly "making us stupid" and shattering our concentration into the bargain. It's also allegedly leading to an epidemic of plagiarism. File sharing is destroying music, online news is killing newspapers, and Amazon is killing bookshops. The network is making a mockery of legal injunctions and the web is full of lies, distortions and half-truths. Social networking fuels the growth of vindictive "flash mobs" which ambush innocent columnists such as Jan Moir. And so on.

All of which might lead a detached observer to ask: if the internet is such a disaster, how come 27% of the world's population (or about 1.8 billion people) use it happily every day, while billions more are desperate to get access to it?

So how might we go about getting a more balanced view of the net ? What would you really need to know to understand the internet phenomenon? Having thought about it for a while, my conclusion is that all you need is a smallish number of big ideas, which, taken together, sharply reduce the bewilderment of which Castells writes so eloquently.

The most common — and still surprisingly widespread — misconception is that the internet and the web are the same thing. They're not. A good way to understand this is via a railway analogy. Think of the internet as the tracks and signalling, the infrastructure on which everything runs. In a railway network, different kinds of traffic run on the infrastructure — high-speed express trains, slow stopping trains, commuter trains, freight trains and (sometimes) specialist maintenance and repair trains.

On the internet, web pages are only one of the many kinds of traffic that run on its virtual tracks. Other types of traffic include music files being exchanged via peer-to-peer networking, or from the iTunes store; movie files travelling via BitTorrent; software updates; email; instant messages; phone conversations via Skype and other VoIP (internet telephony) services; streaming video and audio; and other stuff too arcane to mention.

And (here's the important bit) there will undoubtedly be other kinds of traffic, stuff we can't possibly have dreamed of yet, running on the internet in 10 years' time.

So the thing to remember is this: the web is huge and very important, but it's just one of the many things that run on the internet. The net is much bigger and far more important than anything that travels on it.

Understand this simple distinction and you're halfway to wisdom.
