Network Exponentials Network vs. computer performance

– Computer speed doubles every 18 months– Network speed doubles every 9 months– Difference = order of magnitude per 5 years

1986 to 2000– Computers: x 500– Networks: x 340,000

2001 to 2010– Computers: x 60– Networks: x 4000

Moore’s Law vs. storage improvements vs. optical improvements. Graph from Scientific American (Jan-2001) by Cleo Vilett, source Vined Khoslan, Kleiner, Caufield and Perkins.
