Moore\u2019s Law is a computing term which originated around 1970; the simplified version of this law states that processor speeds, or overall processing power for computers will double every two years.\u00a0 A quick check among technicians in different computer companies shows that the term is not very popular but the rule is still accepted.<\/p>\n

To break down the law even further, it specifically stated that the number of transistors on an affordable CPU would double every two years (which is essentially the same thing that was stated before) but \u2018more transistors\u2019 is more accurate.<\/p>\n

If you were to look at processor speeds from the 1970\u2019s to 2009 and then again in 2010, one may think that the law has reached its limit or is nearing the limit.\u00a0 In the 1970\u2019s processor speeds ranged from 740 KHz to 8MHz; notice that the 740 is KHz, which is Kilo Hertz \u2013 while the 8 is MHz, which is Mega Hertz.<\/p>\n

From 2000 \u2013 2009 there has not really been much of a speed difference as the speeds range from 1.3 GHz to 2.8 GHz, which suggests that the speeds have barely doubled within a 10 year span.\u00a0 This is because we are looking at the speeds and not the number of transistors; in 2000 the number of transistors in the CPU numbered 37.5 million, while in 2009 the number went up to an outstanding 904 million; this is why it is more accurate to apply the law to transistors than to speed.<\/p>\n

With all this talk of transistors the average technician or computer user may not understand what the figures mean; a simpler way to explain is that the earlier CPUs on the market had a single speed or frequency rating while the newer models have a rating which refers to more than one CPU.<\/p>\n

The limitation which exists is that once transistors can be created as small as atomic particles, then there will be no more room for growth in the CPU market where speeds are concerned<\/p>\n\n\t\t\t
