COMPUTERS

History of Computers.
Long and a fascinating history.
 Started with huge and complicated
machines.
 First, second, third and fourth Generation.
 Exponential progress.
 Compare computers before and today

Future computers

Quantum computers.

Nano Computers.

DNA Computers.

Optical Computers.
Quantum computers

A quantum computer is a computer that makes direct use
of distinctively quantum mechanical phenomena to
perform operations on data.

Data is measured by qubits.

Quantum properties of particles can be used to represent
and structure data, and quantum mechanisms can be
devised and built to perform operations with these data.

neutral or chargeless atoms, trapped like individual eggs
in an egg carton by a lattice created by interfering laser
beams and super cooled to the point of zero motion, will
work for quantum computing. Contd…

Replacing transistors with single atoms.

Quantum computer, allows you to enter all possible
inputs at one time and perform all the corresponding
computations in parallel.

Quantum computer would simultaneously carry out a
number of computations equal to two to the power of the
number of input bits

Solve a number of problems conventional computers
cannot.

It can be used to crack secret codes or to communicate
information more securely .

Nano Computers

Nanotechnology is the process whereby matter is
manipulated at the atomic level, providing the ability to
“build” objects from their most basic parts.

November 1st, 2011 that's the day Nanocomputer Dream
Team unveil a revolutionary kind of computer, the most
powerful ever seen.

It will be used to control simple molecular construction
machines, which can then build more complex molecular
devices, ultimately giving complete control of the
molecular world.

Immensely difficult problem of physically piecing together
molecular structures.

Massive calculations are required to determine if
particular molecular configurations are even possible.

Already in use in many places, providing everything from
stain resistant clothing to better suntan lotion.
DNA Computers
Use DNA to store information and perform complex
calculations.
 Vast amount of storage capacity.
e.g a single gram of DNA can hold as much information as
one trillion compact discs.
 Dr. Leonard Adleman has shown that DNA can be used
to solve complex mathematical problems
 used for the first time to find the only correct answer from
over a million possible solutions to some computational
problems.

Optical Computers

The computers we use today use transistors and
semiconductors to control electricity. Computers of the
future may utilize crystals and metamaterials to control
light.

Optical computers make use of light particles called
photons.

Electrons travel between transistor switches on metal
wires or traces to gather, process and store information.
The optical computers of the future will instead use
photons traveling on optical fibers or thin films to perform
these functions.

The speed of computers becomes a pressing problem as
electronic circuits reach their maximum limit in network
communications.

"What we are accomplishing in the lab today will result in
development of super-fast, super-miniaturized, superlightweight and lower cost optical computing and optical
communication devices and systems," - Dr. Donald
Frazier (NASA scientist)
