moore’s law

number of transistors per square inch on an integrated chip doubles every 18 months

moore’s law implications

computers are getting exponentially faster, cost of data processing is approaching 0

metcalfe’s law

value of a network = square of the number of users connected to it

metcalfe’s law implications

more digital devices are being connected together, value of digital & social networks is increasing exponentially

nielsen’s law

network connection speeds for high-end users will increase by 50% per year, take half of a half then add that.

nielsen’s law implications

network speed is increasing. higher speeds enable new products, platforms, & companies

kryder’s law

storage density on magnetic disks is increasing at an exponential rate

kryder’s law implications

storage capacity is increasing exponentially, cost of storing data is approaching 0
