alculations is called a DNA puter. It was in 1994 that University of Southern California puter scientist Leonard Adelman suggested that DNA could be used to solve plex mathematical problems. While still in their infancy, DNA puters will be capable of storing billons of times more data than your personal puter. OPTICAL COMPUTER An optical puter is a puter that uses light instead of electricity. An optical puter uses photons to manipulate, store and transmit data. You also know the modern electric puter use transistors. In optical puters electronic ponents are replaced with optical ones and ‘optical transistors’ must be used. Optical puter technology is still in early stages. CHEMICAL COMPUTERS A chemical puter is an unconventional puter based on a semi – solid chemical ‘soup,’ where data is represented by varying concentration of chemicals. The putations are performed by naturally occurring chemical reactions. So far, it still in very early experimental stage, but may have great potential for the puter industry. NANO COMPUTER A nano puter is a puter that is microscopic size. It is smaller than micro puter, which is smaller than mini puter. We can also say it is a puter whose fundamental parts are no bigger than a few nanometers. It is monly used nano technology which is the building of extremely small machines. WETWARE COMPUTERS A wetware puter is an organic puter. Organic refers any thing that is derived from living organisms. A wetware puter is from living neurons, which are cells found in brain, spinal column and nerves. A wetware puter is some times called an artificial organic brain or a neuroputer. A wetware puter has already been constructed from leech neurons. SHOE COMPUTERS A shoe puter is a type of puter that uses law level electrical impulses emitted by our bodies, when we walk we generate the energy, and this energy powers the processors of the puter.
