Moore's Law, a well-known principle in the computer world, states that every 18 months the speed at which microprocessors perform calculations doubles, and the price of hardware falls by half. This accelerates the rate at which computers become obsolete, and the life cycle of computer equipment, which was once as much as six years, has been growing ever shorter.
電腦界有所謂的「摩爾定律」，電腦中央處理機的運算速度，每十八個月加速一倍，售價下降一半，也加速電腦報廢的速度，使得電腦的生命周期，從平均六年不斷向下縮短。
