Nano Computing Revolution and Future Prospects
Recent Research in Science and Technology 2012, 4(3): 16-17 ISSN: 2076-5061 Available Online: http://recent-science.com/ Nano computing revolution and future prospects Deepti Hirwani and Anuradha Sharma Maharaja Agrasen International College, Raipur C.G, India Abstract There are several ways nanocomputers might be built, using mechanical, electronic, biochemical, or quantum technology. It is unlikely that nanocomputers will be made out of semiconductor transistors (Microelectronic components that are at the core of all modern electronic devices), as they seem to perform significantly less well when shrunk to sizes under 100 nanometers.The research results summarized here also suggest that many useful, yet strikingly different solutions may exist for tolerating defects and faults within nanocomputing systems. Also included in the survey are a number of software tools useful for quantifying the reliability of nanocomputing systems in the presence of defects and faults. Keywords: Nano computing, electronic devices, technology INTRODUCTION classical computer would have to repeat 2 x input numbers, Nanocomputer is the logical name for the computer smaller performing the same task that a classical computer would have to then the microcomputer, which is smaller than the minicomputer. repeat 2 x times or use 2 xprocessors working in parallel. In other (The minicomputer is called “mini” because it was a lot smaller than words a quantum computer offers an enormous gain in the use of the original (mainframe) computers.) More technically, it is a computational resources such as time and memory. This becomes computer whose fundamental part is no bigger than a few mind boggling when you think of what 32 qubits can accomplish. -

Numerous small and low-‐cost spacecraft have been launched, often based on the CubeSat format. There is an emerging recognition that nano-‐satellites (1-‐10 kg) and micro-‐satellites (10-‐100 kg) will play a major scientific role in space exploration. A critical enabling technology that is required to revolutionize planetary space exploration with small satellites is a suitable efficient compact propulsion system. Under the constraints of high delta-‐V missions, this necessarily leads to an electric propulsion requirement. The MicroThrust consortium has developed a breadboard of a highly efficient microfabricated electric propulsion system prototype to -‐ enable sub 50 kg satellites to perform large orbit changes, thus allowing small satellites to perform exploration missions and mission chitectures ar that were not possible up till now. -

Now set yourself down in front of the typewriter — and write the damned thing!" In Re John D. Clark by Isaac Asimov I first met John in 1942 when I came to Philadelphia to live. Oh, I had known of him before. Back in 1937, he had published a pair of science fiction shorts, "Minus Planet" and "Space Blister," which had hit me right between the eyes. The first one, in particular, was the earliest science fiction story I know of which dealt with "anti-matter" in realistic fashion. Apparently, John was satisfied with that pair and didn't write any more s.f., kindly leaving room for lesser lights like myself. -
