NANOTECHNOLOGY: This is science, technology from a very infinitesimal point of consideration that is thee nanoscale which is about 1 to 100 nanometers.
Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering. Nanotechnology is not just a new field of science and engineering, but a new way of looking at and studying
BASIC CONCEPT OF NANOSCIENCE
It’s hard to imagine just how small nanotechnology is. One
nanometer is a billionth of a meter, or 10-9 of a meter. Here are a few
illustrative examples:
- A sheet of newspaper is about 100,000 nanometers thick
- On a comparative scale, if a marble were a nanometer, then one meter would be the size of the Earth

Nanoscience and nanotechnology involve the ability to see
and to control individual atoms and molecules. Everything on Earth is made up
of atoms—the food we eat, the clothes we wear, the buildings and houses we live
in, and our own bodies.
GRID COMPUTER: Imagine several million computers from all over the world,
and owned by thousands of different people. Imagine they include desktops,
laptops, supercomputers, data vaults, and instruments like mobile phones, meteorological
sensors and telescopes...
Now imagine that all of these computers can be connected to
form a single, huge and super-powerful computer! This huge, sprawling, global
computer is what many people dream "The Grid" will be.
this is how the idea of grid computer looks like.
"The Grid" takes its name from an analogy with the
electrical "power grid". The idea was that accessing computer power
from a computer grid would be as simple as accessing electrical power from an
electrical grid".
Though the concept isn't new, it's also not yet perfected.
Computer scientists, programmers and engineers are still working on creating,
establishing and implementing standards and protocols. Right now, many existing
grid computer systems rely on proprietary software and tools. Once people agree
upon a reliable set of standards and protocols, it will be easier and more
efficient for organizations to adopt the grid computing model. We may consider the server of an cyber cafe as a grid computer .
QUANTUM COMPUTERS: Quantum computing is the area of study focused on developing
computer technology based on the principles of quantum theory, which explains
the nature and behavior of energy and matter on the quantum (atomic and
subatomic) level. Development of a quantum computer, if practical, would mark a
leap forward in computing capability far greater than that from the abacus to a
modern day supercomputer, with performance gains in the billion-fold realm and
beyond. The quantum computer, following the laws of quantum physics, would gain
enormous processing power through the ability to be in multiple states, and to
perform tasks using all possible permutations simultaneously. Current centers
of research in quantum computing include MIT, IBM, Oxford University, and the
Los Alamos National Laboratory.

brief history on the origin of quantum computers
The essential elements of quantum computing originated with
Paul Benioff, working at Argonne National Labs, in 1981. He theorized a
classical computer operating with some quantum mechanical principles. But it is
generally accepted that David Deutsch of Oxford University provided the
critical impetus for quantum computing research. In 1984, he was at a
computation theory conference and began to wonder about the possibility of
designing a computer that was based exclusively on quantum rules, then
published his breakthrough paper a few months later. With this, the race began
to exploit his ideas. However, before we delve into what he started, it is
beneficial to have a look at the background of the quantum world. The biggest question in my mind and probably the minds of other is that how well is this going to be authentic and function? Lets keep our fingers cross until that time!
SEMANTIC WEB: Semantic Web is
focused on machines unlike the web 2.0 which focus on humans. The Web requires a human operator, using computer systems
to perform the tasks required to find, search and aggregate its information.
It's impossible for a computer to do these tasks without human guidance because
Web pages are specifically designed for human readers. The Semantic Web is a
project that aims to change that by presenting Web page data in such a way that
it is understood by computers, enabling machines to do the searching,
aggregating and combining of the Web's information — without a human operator.

WHO USES SEMANTIC WEB?
It has taken years to put the pieces together that comprise
the Semantic Web, including the standardization of RDF, the W3C release of the
Web Ontology Language (OWL), and standardization on SPARQL, which adds querying
capabilities to RDF. So with standards and languages in place, we can see
Semantic Web technologies being used by early adopters.
Semantic Web technologies are popular in in areas such as
research and life sciences where it can help researchers by aggregating data on
different medicines and illnesses that have multiple names in different parts
of the world. On the Web, Twine is
offering a knowledge networking application has been built with Semantic Web
technologies. The Joost online television service also uses Semantic technology
on the backend. Here Semantic technology is used to help Joost users understand
the relationships between pieces of content, enabling them to find the types of
content they want most. oracle offers a Semantic Web view of its Oracle
Technology Network, called the OTN Semantic Web to name a few of those
companies who are implementing Semantic Web technologies. Let us see how its works!
FOOD FOR THOUGHT
Will the world cease to exist if technology stops to advance?
