Document Summary

Moore"s law :the number of transistors per square inch on an integrated chip (circuit) doubles every 18 mo. drive for economy. Information age: period in history where production, distribution, and changing of information is. Digital revolution: conversion of mechanical and analogue devices to digital. Bell"s law: new computer class formed each decade forming new industry. Thanks to moores law the cost of data processing is approaching zero, are being held back because cost. However, innovations are held back because cost of sufficient processing powers are high. Metacafe"s law: network values equal to square number of users connected to it (v=u^2), which means more digital service increases digital value. (ex: google, amazon, ebay exist due to large number of internet users) Nielsen"s law: network connection speed will increase by 50% for high end users. Kryder"s law: storage density on disk is increasing at an exponential rate and the cost of storing data approaching zero.
