Transcripts - nano computing- basics
Nano computer is the logical name for a computer smaller than
the minicomputer. The term nano computer is used to refer to general
computing devices of size comparable to a credit card.
It is now used for a wider range of devices, such as Arduino,
BeagleBoard, Olinuxino,Odroid,Miracast dongles, All the PC-on-a-
stick (MK802 series...), Raspberry Pi. The fundamental parts are no
bigger than a few nanometer.
Nano computers will be made out of semiconductor transistors .The
only technology that is required to build nano computers, is
the molecular assembler. There are no commercially available
nano computers in existence at this time.
Current-day computer chips are still very inefficient, two-
dimensional, bulky and crude. Nanotechnology will enable the
creation of nano computers that pack in as many transistors per
unit volume as the limits of the atomic structure of matter
permit. They will be far more efficient, producing much less
waste heat and therefore allow for "stacking" of transistor
elements to be into the third dimension.
According to Moore’s law ,

will fit on a silicon chip

Electronic nano computers would
operate in a manner similar to the
way present-day microcomputers
work. The main difference is one of
physical scale. More and more
transistors are squeezed
into silicon chips with each passing

integrated circuits ( IC s) capable of
ever-increasing storage capacity and
Chemical and biochemical nano
computers would store and process
information in terms of chemical
structures and interactions.
Biochemical nano computers
already exist in nature; they are
manifest in all living things.
Mechanical nano computers would
use tiny moving components called
nanogears to encode information.
Such a machine is reminiscent
of Charles Babbage 's analytical
engines of the 19th century.
A quantum nano computer would
work by storing data in the form of
atomic quantum states or spin.
Technology of this kind is already
under development in the form of
single-electron memory (SEM) and
quantum dots. The main problem
with this technology is instability.
Nano computing would work
by storing data in the form of
atomic quantum steps or spin.
There are several methods of
nano electronic data storage
currently being researched.
Among the most promising
methods are set electron
transistors and quantum dots.
All of these devices function
based upon the principles of

Current nano computing research involves the study of very small electronic
devices and molecules, their fabrication, and architectures that can benefit
from their inherent electrical properties. Nanostructures that have been studied
include semiconductor quantum dots, single electron structures, and various
molecules. Very small particles of material confine electrons in ways that large
ones do not, so that the quantum mechanical nature of the electrons becomes
Quantum dots behave like artificial atoms and molecules in that the electrons
inside of them can have only certain values of energy, which can be used to
represent logic information robustly.

like memory and
backing storage, will

New technologies will be
created to replace
New standards and
architectures will be
needed to make use of
the new systems when
they are created.
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.
We always use the latest generation of technology to create
the next generation of technology, which causes a
compounding effect on the resultant power and capabilities
of that technology.
