Let’s get to know to emerging technologies….


In this era of information explosion, information and communication technology (ICT) are becoming more important. Almost every time people use technology, it is because people can dominate and control almost everything in the fingertips. Country that does not prioritize in ICT will be the mainstream of development. ICT progress has brought many benefits to individuals, communities and nations. Now, the technology has emerges to its fullest potential. The advancement has revolutionized to innovation in various field of modern technology. These are some list of emerging technologies:

1) Nanotechnology


Nanotechnology can be described as big things from a tiny world. A basic definition: Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced (CRN,2008). Nanotechnology has started since the year of 1980’s, by K.Eric Dexler. At that time, he was talking about building machines on the scale of molecule, a few nanometers wide—motors, robot arms, and even whole computers, far smaller than a cell. Before we go further, lets first understand how small nanometer is; A nanometer (nm) is one-billionth of a meter, smaller than the wavelength of visible light and a hundred-thousandth the width of a human hair [source: Berkeley Lab]. As small as a nanometer is, it is still large compared to the atomic scale. Nobel Prize Winner Dr. Horst Stormer has claimed that nanoscale is more interesting than the atomic scale because the nanoscale is the first point where we can assemble something – it is not until we start putting atoms together that we can make anything useful. Nanotechnology is so new; no one is really sure what will come of it. Even so, predictions range from the ability to reproduce things like diamonds and food to the world being devoured by self-replicating nanorobots.

2) Grid Computing

Have you ever heard about grid computing? Let’s see how it is function and benefits the world! At its most basic level, grid computing is a computer network in which each computer's resources are shared with every other computer in the system. How is Grid different from other technologies such as Clusters/P2P/ASP? The key distinction between clusters and grids is mainly lie in the way resources are managed. In case of clusters, the resource allocation is performed by a centralized resource manager and all nodes cooperatively work together as a single unified resource. In case of Grids, each node has its own resource manager and don't aim for providing a single system view. The grid computing concept isn't a new one. It's a special kind of distributed computing. In distributed computing, different computers within the same network share one or more resources. To make this understanding more fun, grid computing could be illustrated by this simple story:

“You and couple of friends is going to sit for examination, all of you decided to form a study group in order to share the resources, you are master in mathematics and you going to share the knowledge with the others. The other friends offer to share some programming knowledge. During the group study, the three of you share your knowledge and skills to make the study more efficient. If you had made the study on your own, you would need more time to assemble the resources you would need and you probably would have had to work a lot harder”.

3) Quantum Computing


The definition of quantum computing is complicated as its name. Heard people talking about quantum computing, but not really sure you understand what they mean? Here I have some basic information what is quantum computing about. The question here will we ever have the amount of computing power we need or want? One day it will not be enough for us, if we look through the large amounts of data generated by scientific research, the proliferation of personal computers or the emergence of the Internet, which have only fueled our need for more, more and more computing power. If, as Moore's Law states, the number of transistors on a microprocessor continues to double every 18 months, the year 2020 or 2030 will find the circuits on a microprocessor measured on an atomic scale. And the logical next step will be to create quantum computers, which will harness the power of atoms and molecules to perform memory and processing tasks (Bonsor, K. & Strickland, J. 2013).

A wise man once said that investigators are eagerly describing what the more sophisticated machines will be like if they can ever be constructed is quantum computation. Perhaps the most surprising thing about quantum computing is that it was so slow to get started. Physicists have known since the 1920s that the world of subatomic particles is a realm apart, but it took computer scientists another half-century to begin wondering whether quantum effects might be harnessed for computation. The answer was far from obvious (Grover L.K, 1999).   Honestly I open 5-6 tabs to find quantum computing information, most of them delivered they information in a very complicated way, but finally I found one article that help me to understand it, so for more details please click on this link, to go to the article. 

4) Semantic Web

Now, let’s turn our attention to the next emerging technology called Semantic Web. According to semanticweb.org the semantic web is the extension of the World Wide Web that enables people to share content beyond the boundaries of applications and websites. The Semantic Web proposes to help computers "read" and use the Web. The big idea is pretty simple -- metadata added to Web pages can make the existing World Wide Web machine readable. This won't bestow artificial intelligence or make computers self-aware, but it will give machines tools to find, exchange and, to a limited extent, interpret information.
