The notion that computers could be linked together is 40 yeas old this month,
which marks the delivery of the technical paper which coined the phrase "packet
switching".
Donald Davies was working at the UK's
National
Physical Laboratory (NPL) in Middlesex when he delivered a paper in August
1968 which detailed how distinct packets of data could be sent over public
telephone and later dedicated networks.
Davies then set about actually building what is claimed to be the world's
first local area network (LAN) at the NPL, which consisted of approximately half
a dozen nodes each with three or four machines attached.
"This was more than just an idea, they actually built the first LAN," said
chief scientific advisor at the NPL, Prof. John Pethica
Davies was asked to present his ideas to the US Advanced Research Project
Agency (Arpa) which was then working on the development of the precursor to the
modern internet.
