Happy 40th Birthday Arpanet!

The first step towards the internet, DARPA's Arpanet, took place 40 years ago this week. The BBC reports on how a remote login was established between UCLA and Stanford networks, with the intention of better utilisation and sharing of computer resources. The test proved that it was possible to connect two networks with a telephone line. The test proved that packet switching (breaking large messages down into chunks and sorting them like a post office sorting office) was more efficient than having to wait for a complete message to arrive before forwarding it. This was the first step towards a "network of networks", the building blocks of todays internet.
