It\u2019s forty five years since the commercial introduction of the first microcomputer chip set which evolved into the modern microprocessor, changing computers from tools for scientists into the engines which power today\u2019s electronic consumer appliances. So how did the silicon chip evolve and where might this revolution be heading next?\nBridget Kendal is joined by four distinguished computer and internet pioneers who helped spearhead some of the most important inventions of the computer age. \nVinod Dham invented the first Pentium micro-processor and went on to become Vice-President at the world\u2019s largest chip maker-Intel. His early work in this field earned him the nickname \u201cThe Father of the Pentium chip.\u201d Sophie Wilson\u2019s computer design was used to build the Acorn Micro-Computer. She also led the development of the ARM microprocessor, found in over half of the world\u2019s consumer electronics. David Laws is a technology historian and a curator of the Computer History Museum in California. Dame Wendy Hall is a Professor of Computer Science at the University of Southampton in the UK.
