2. What is nano computing?
• Nano computing describes computing that
uses extremely small, or nano scale, devices.
• Nano computing come from two sources:
• It will be integrated into existing products and technology
(disk drives, for example).
• Fundamentally new products, software, and architectures will
be developed.

3. Why bother?
• Nano computing change the computer
industry in many ways.
• Existing technologies, like memory and backing storage, will
become even more plentiful than they already are.
• New technologies will be created to replace obsolete
machines.
• New standards and architectures will be needed to make use of
the new systems when they are created.
• All of this requires enormous effort and
resources. So why bother?

4. Types of nano computers
• Nano electronic computers
• Nano mechanical computers
• Nano chemical and biochemical computers
• Nano Quantum computers

5. Basic terms
• Quantum-Computer : A quantum computer
is a machine, that performs calculations based
on the behavior of particles at the sub-atomic
level .
• Qubits : Engineers have coined the term qubit
( pronounced KYEW - bit ) to denote the
fundamental data unit in a quantum computer.

6. Basic terms (contd…)
• Teleportation: it involves dematerializing an
object at one point, and sending the details of that
object's precise atomic configuration to another
location, where it will be reconstructed.
• Quantum mechanics :a quantum computer
involves quantum mechanics quantum computer
uses subatomic particles, such as electrons and
protons, to solve problems

7. Devices of nano computing
ipad, iPhone, HP Slate, Android devices like ICD Gemini etc

8. How nano computing works?
• 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 transistors and quantum
dots.
• All of these devices function based upon the
principles of quantum mechanics…

9. Potential
• The simple answer is that it should be worth it
• Nano computers could be small enough to fit in a
jacket pocket and still have enough storage to fit all
of today’s Internet and more
• The same computer would have processing
capabilities surpassing today’s super computers by
far.
• Not for at least 15 years, though.

10. Risks in nano computing
• Electrons 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 to cool it.

11. Application of nano
technologies
• Washing machine that inhibits bacterial
growth it washes the cloths.
• It is on the market today and 60% of cars
these fuel lines.
• They make a refrigerator.
• Contact lens that let you check your blood
sugar level by looking at a mirror.

12. Advantages
• High computing performance
• Low power computing
• Easily portable flexible
• Faster processing
• Lighter and small computer devices
• Noise Immunity: isolating the circuits
from noise from both inside and outside
the circuit.

13. Disadvantages
• Possible loss of jobs in the traditional farming and
manufacturing industry
• It is very expensive and developing it can cost you
a lot of money. It is also pretty difficult to
manufacture, which is probably why products made
with nanotechnology are more expensive.
• These particles are very small, problems can
actually arise from the inhalation of these minute
particles.
• Products made with nanotechnology are more
expensive.

14. Future of nano computing
• National science and technology council
(USA) claim that
“Nano computing is an enabling
technology that change the nature of
almost every human made object in the
next century.”
