Here is a link to Wikipedia: Moore's Law
Moore’s law is the observation made in 1965 by Gordon Moore, the famous chip manufacturer Intel Corporation co-founder. The law dictates that about every 18 months, the number of transistors will be doubled, the performance will also be doubled, when the price unchanged; or that with an amount of money to buy a computer today, you can buy a computer which has double performance in 18 months later. Moore's Law summed up the speed of advances in information technology.
As you can see in the video above, it has well visualized the Moore’s Law. Only 30 years, a computer from a mysterious giant monster has become an indispensable tool for most people. Information technology which was only available in laboratories has now been brought into countless ordinary family and the world been linked to the Internet, multimedia, audio visual equipment to enrich the lives of everyone.
Lets examine the Moore’s Law by looking at the three main components of a computer: CPU, Memory, and Storage. Back to year 1982, we had 80286; 1985, 80386; 1989, 80486; and 1993 the first Pentium, then 1997 Pentium II. Nowadays, what do we have? We got a 2nd Gen Intel Core i7 at just about $200. With that $200; we can’t even buy a floppy drive back then. Things are getting more powerful whilst prices getting lower and lower. At the same time, internal memory capacity expanded from 480K to 8M, 16M. Now, 16 Gigabyte is nothing so uncommon. In the old year, computer storage capacity was so limited. We all may remember Prof. Kent’s story, how much he spent on a floppy drive and compare to how much we can buy a 2 Terabyte today at any store? We can see that there’s a huge different in capacity and price only in a decade.
Moreover, the Moore’s Law seems not only applied to computer components but also to digital electronic device like mobile phone, tv, and digital camera. The capabilities of many digital electronic devices are strongly linked to Moore's law: processing speed, memory capacity, sensors and even the number and size of pixels in digital cameras. All of these are growing in exponential rate and this growth trend will be continued.
We should keep in mind that Moore’s law is not mathematics or physical laws but rather a trend analysis or forecasting. However, it is pretty accurate and effective. As we can see, technology is getting faster, more powerful, and more affordable. Some experts have argued that the law will eventually obstruct in near future, but let’s assume they’re wrong, then one day we should not be surprised when we see a computer like one appeared in the following video.
