IT Technology is Changing! From the Era of Computer
to the Era of Network
Overview of the Changing environment of IT Technology First of all, let's see changing environment of the software technology.
A remarkable change has been witnessed in the past decade.
It was basically an advancement of hardware that enabled such a change.
This kind of change started from hardware technology heading to the network is one of the significance in 21st century.
Thus, it is obvious that a continual change will persist in the IT technology.
Changes of Software Java is 10 years old.
XML is 7 years old.
Web Service is 5~6 years old.
2005-2006: EJB3.0, JBI, SCA, …
The Laws of Moore and Gilder SOA has been appeared in the Network during tremendous historical background which is also known as advancement of paradigm shift from computer to Network.
Network can provide the services!
The Law of Moore In every 18 months, the number of transistors in a circuit will reach 2 times, whereas the price will be reduced into half, the prediction widely known as Moore’s law has already been 40 years since it has been published. Now, as we look back at 30 years of its development, will the progress of approximately 1000 folds in 15 years be continued from now on too?

“Moore’s Law Limit” It is the fact that the growth of semiconductors technology in such degree had continued exponentially, however, there is a limit on it. If growth continues at this speed, finally, it means that one electron has to bear the information of a single bit.
Furthermore, this law will probably be invalid within a decade.
With the existing technology, it would be so difficult to produce a chip of Tera bit memory, similarly, it would almost be impossible to produce a chip of Peta bit memory.

Exploring for a new principle
To exceed this limit, many information can be stored in a single electron as a superposition of multi state of the information. Quantum Computing

Road Map for Quantum Computing
However, even in the context of relatively optimistic research and development projects, it is said that the feasibility of the quantum computing technology will require 20-30 years more to come. In fact, the goal of implementation has not yet been in their sight. Implementation of Encrypted network technology 2020
Implementation of Quantum communication network 2030
Implementation of general-purposed quantum computer 2035 onward
The law of Gilder If we believe Moore’s law will be invalid within a few year, and if the implementation of quantum technology of the next generation is also not in the sight, then, what will support/pull the IT technology in the future?
According to the law of Gilder, the growth of network speed will doubles in every 6 months. Enlargement of such kind of bandwidth is due to the contribution of optical fibers network technology.
