Where would we be without access to all that astonishing information, email and messaging, shopping, blogs, home videos and bad jokes?
Tangled Web. There would be no web without the internet. Before its invention, you could only connect to one other computer at a time, using an expensive telephone connection.
The internet began as a computer network in the US defense department, which was designed to let computers communicate with one another even if there were a nuclear war. Thankfully, Armageddon never arrived, but the internet did.
It was made possible by ‘packet switching’, a way of sending data invented in the 1960s by Donald Davies and Paul Baran, working independently of one another in the UK and the USA.
Most people’s experience of the internet is the World Wide Web, all those billions of pages of incredibly useful, or sometimes completely useless, stuff. That was invented by an English computer scientist called Tim Berners-Lee who was working for the European Center for Nuclear Research (CERN) in Switzerland.
His invention meant that the information on the internet was much easier to get at, and made it possible to easily transfer text, images, sound and video. The web was being used by the scientists at CERN in 1990, and the following year it was available for everyone. Today there are more than 1 billion users around the world.
info.cern.ch is the address of the first ever website, created in 1990. The indexed World Wide Web now contains over 14 billion pages – and that’s just the indexable pages (the ones everybody can find on search engines). And there are new ones added every day.
A network roughly demonstrates how your router sends and receives information via the internet. Once requested, the information travels through a series of connections, including modems, ISP (Internet Service Providers) ports and reefers.
Routers help to get your messages from one computer to another. There is not one set route to send information – it depends on which will be quickest. The combinations are limitless, but you still end up with the same information.
