Packet switching is one of the crucial technologies that made the internet possible.
It's 40 years since the technique was invented by a team at the National Physical Laboratory (NPL) in Bushy Park, Middlesex, led by professor Donald Davies (pictured in 1974).
Speaking to silicon.com, NPL chief scientist, professor John Pethica explained: "The whole idea of packet switching is what underlies the idea of a set of distributed nodes, which is now the internet. It's the hardware side of the internet."
