What is this???

Nanotechnology:

Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced. (http://crnano.org/benefits.htm). Besides, there have a lot of advantages can we obtain from nanotechnology.

1.      Advanced nanotech can solve many human problems.

2.      Many diverse problems are related to water.

3.      Cheap greenhouses can save water, land, and food.

4.      Nanotech makes solar energy feasible.

5.      Living spaces can be greatly improved.

6.      Computers will be cheap enough for everyone.

7.      Nanotech can help the environment.

The advantages of nanotechnology were really help users not only in one element but it is covered major of element.

Grid computing:

Grid computing is a service for sharing computer power and data storage capacity over the Internet. Grid computing uses the Internet to help us share computer power, while the Web uses the Internet to help us share information. There have information regarding this services in http://www.gridcafe.org/grid-in-30-sec.html.

Grid computing is making big contributions to scientific research, helping scientists around the world to analyze and store massive amounts of data.

In grid computing reality, there are already hundreds of grids around the world, each one created to help a specific group of researchers, or a particular group of users. And across the world, researchers and software engineers are working to bring “the Grid” closer to achieving the dream.

 Quantum Computing:

Quantum computing relies on quantum physics by taking advantage of certain quantum physics properties of atoms or nuclei that allow them to work together as quantum bits, or qubits, to be the computer’s processor and memory.

A quantum computer can do an arbitrary reversible classical computation on all the numbers simultaneously, which a binary system cannot do, and also has some ability to produce interference between various different numbers.

Quantum computing is not well suited for tasks such as word processing and email, but it is ideal for tasks such as cryptography and modelling and indexing very large databases. To get more detailed please refer to http://www.webopedia.com/TERM/Q/quantum_computing.html.

Semantic Web:

The Semantic Web is the extension of the World Wide Web that enables people to share content beyond the boundaries of applications and websites. It has been described in rather different ways: as a utopic vision, as a web of data, or merely as a natural paradigm shift in our daily use of the Web. Most of all, the Semantic Web has inspired and engaged many people to create innovative semantic technologies and applications. This info take from
