Nano Computer Technology
The computer has already gone through a dynamic revolution. Thirty years ago, computers were the size of a room and incredibly slow. Few people probably would have imagined supercomputers that can do over a trillion calculations per second. Today, he average person’s desktop computer is more powerful than the fastest computers were 30 years ago. The only way this can continue is if a new type of computer is developed. his computer is known as a nano computer. It may one day replace the modern computer due to many economic and scientific constraints that will one day halt the odern computer’s advancement.
The constraints for computers come from the circuits that form them. The most important component of a computer is its “brain”, commonly referred to as the central processing unit. Computer chip manufacturers, such as Intel, spend billions of ollars to build plants and do research that will allow these chips to shrink in size. However, the costs of research and plants are increasing at a substantial rate. Once the omponents of these chips come close to the size of atoms, the costs to build plants may be in the trillions of dollars (Ellis). What’s worse is nothing can become smaller than an tom, so advances in computer speed will not be possible. However, two upsides do exist. Scientists estimate the end will come around the year 2010, and scientists are orking on developing a nano computer (Markoff). 
The earliest computers, built in the middle of the 20th century, used vacuum tubes for switching. These machines were so massive and bulky, and demanded so much electricity to operate, that they required buildings and power plants of their own. In addition ,they used more processing power as well as much more energy . So,Scientists needed to shrink computers to make them more powerful.as The smaller an electronic ystem can be made, the more processing power can fit into a given physical volume, the less energy is required to run it, and the faster it can work (because distances among components are reduced, minimizing charge-carrier transit time).
