Moore"s law - # of transistors per square inch on integrated chip doubles every 18 months. Increasing processing power has enabled new devices, applications, companies, and platforms. Metcalfe"s law value of a network = square of the number of users connected to it. As more digital devices connected together, value of that network will incr. Nielsen"s law network connection speeds for high-end users will incr by 50% per year. Faster networks new companies, new products, new platforms. Kryder"s law storage density on magnetic disks is incr at exponential rate. Abstract reasoning ability to make and manipulate models.
