A modern cell phone has more computer power than all of NASA back in 1969, when it placed two astronauts on the moon.

Also, you know that birthday card you can buy that ‘sings’ “Happy Birthday” to you? Remarkably, the tiny chip inside that card has more computer power than did all the Allied forces in 1945! These facts are accounted for by a rule of thumb within the computer industry called Moore’s Law. This ‘law’ was named after Intel co-founder Gordon Moore, who predicted that the processing power of a computer chip approximately doubles every 24 months. This prediction has served as more of a guideline for the industry than an actual rule, but nevertheless is useful in predicting the rapid progression of contemporary technologies. Here’s one more, just to show how quickly technological advancements are made - the PS3, which costs $300, has the power of a military supercomputer of 1997, which cost several million dollars back then!
