3. What is Nano computing Nano computing describes
Those components that uses
Extremely small or nano scale
devices .
Nano computers comes from
Two sources:
It will be integrated into
Existing products and
technology(disk , driver).
Fundamentally new products , software, and architecture will be develop.

4. ARCHITECTURE Two forces driving the needs for new circuits designs
And architecture.
Invention of device and technologies that have completely different principles from FET.
New proccessing technologies combining CMOS function with other functions.
3D integration .
Quantum cell automata.
Quantum computing.

5. MOORE’S LAW
In 1965, engineer Gordon Moore predicted that the number of transistors on an integrated circuit would
Approximately every two years .Today , we call this prediction MOORE’S law , though it is not really a scientific law at all .
Microprocessor manufactures strive to meet the prediction, because if they don’t their

6. TYPES OF NANOCOMPUTING
Electronic nanocomputer.
Chemical & bio-chemical nanocomputers.
Mechanical nanocomputer.
Quantum nanocomputer.

7. ELECTRNIC NANOCOMPUTER
Electronic nanocomputers would operate in a manner simmilar to the way present day microcomputers work.The main difference is the physical scale.
To further decreases the size of the concept , “nanolithography”.

8. NANOLITHOGRAPHY
Nanolithography is the study and application of a number of techniques for creating nanometer scale structure ,meaning patterns with at least one literal dimensions between the size of an individual atom(100nm).

9. Chemical & bio-chemical
Chemical and bio chemical computers would store and process information in terms of chemical structures and interactions .
Bio-chemical nano-computers seems far off because the mechanism for animal brains are not properly understood by humans .
In general terms chemical computer is one that process information in terms of making and braking chemical bonds and stored resulting information in terms of chemical structure .

10. Mechanical Nanocomputers
Computers would be assembled by the mechanical positioning of atoms or molecules at a time.This process is known as “mechanosysthesis”.
Mechanical nanocomputers would use tiny moving components called Nanogears to encode informations.

11. QUANTUM NANOCOMPUTERS
A Quantum nanocomputer would work by storing data in the form of atomic quantum states or spin.
Technology of this is already under development in the form of single-electron memory(SEM)and quantum dots.
An electron can easily fall to a lower energy state , emitting a photon striking an atom can cause one of its electron to jump to a higher energy state.

12. HOW NANOCOMPUTER WORK
Nano computer would work by storing data in the form of atomic quantum states or spin (SEM and quantum dots)
There are several methods of Nano electronic data storage currently being researched among the most promising are set electron transistor and quantum dots.
All of these device function based upon the principles of quantum mechanics

13. APPLICATION OF NANOTECHNOLOGIES
Washing machine that that inhibits bacterial growth it washes the clothes
It is on the market today and 60% of cars these fuel lines
They make a refrigerator
Contact lens that let you check your mind blood sugar level by looking at a mirror

14. Risks in nanocomputing
Electron scientists need to develop new circuits to cope with nano circuits working with carbon nano tubes.
The transistors will be 100 times smaller than the thickness of human hair
The ultra capacitors produces high heat till today there is no remedy given tio cool it.

15. Conclusion
Nano based quantum computers would revolutionize computing and increase their computing power tremendously. It covers the underlying physics , reliability and nano scale quantum , optical and molecular computing.
