Emerging Technologies 2011-12:

Technology is moving too fast, we see change in products every year with new features or new products with new technologies. 4G, aka 4^th Generation in wireless communication systems, an attention getter to every single person related to Networks around the world. 4G wireless technology promises higher data transfer rates and expanded multimedia services. 4G technologies combine WiFi and WiMax. For cellular networks 4G runs at sped ranging from 100 Mbps and for local WiFi speeds ranging from 1 Gbps. It provides framework that merge that existing cellular technology with wireless access systems. The Internet is the driving force for higher data rates and high speed access for mobile wireless users. To achieve that maximum speed 4G technology is being implemented in smart phone and other computing devices.

Semantic Web, a web of data that allow machines to understand that meaning of data or information written over the World Wide Web. Semantic web technologies are making new horizons for the web users. Semantic web data is a part of web data over World Wide Web which is able to process independently of application, domain or any platform. Data stored on webs in the form of documents that cannot be readable or understandable by the computers. User want to search something over the internet, search engine will display all the content whether relevant or irrelevant for user. User have to find again relevant data whereas, in semantic technologies computer reads the word or phrase searched a user using search engine and produce the specific relevant result by the means of artificial intelligence techniques.

In web development area HTML5/CSS both are emerging technologies. HTML5 use the new semantic elements, like Header, Footer, Section, and Aside. Many others, like hgroup, aside, and figure, are logical additions and enhancements to the existing elements of HTML. The special effects in Photoshop design can be converted into web pages in HTML5 without using any JQuery and JavaScript. Audio and video tags in HTML5/CSS make easier for the developers to add audio and video to the web page easiest than ever. They can style theses tags according to their design without any hesitation just like any other normal tag.

For permanent data storage M-Disc technology will be launched in the market soon for commercial purposes. It is a scratch proof disc and can store data for more than 1,000 years into a stone-like metals and metalloids. Normal CDs and DVDs face loss of data in humidity and in high temperature whereas M-Disc is capable to prevent loss of data in such conditions. M-Disc current available storage capacity is 4.78 GB DVD. It cannot be burn in normal writers, 5X stronger laser burners are required to burn M-Disc. But, can be read by normal DVD players as backward compatible technology is used.
Technology is updating in flash, it is hard to keep up with IT trends as it goes a head. But if your are tech savvy there is nothing that can keep you of it.
