To clearly see the role of science and technology in economic growth, it is important to understand the concepts of: what is science, what is technology, between science and technology? Science is a conscious system of phenomena, things, laws of social nature and thought. The purpose of science is to search, to explain the cause of things, phenomena, processes in nature and society of thought. The content of science answers the "why" question. According to the approach from the way of organizing scientific research people divided into basic science and applied science. If science is a consciousness system, technology is a collection of methods, procedures, techniques, know-how, tools, means to convert resources into desired products and services. Technology has four elements: tools, people, information and organization. These four elements interact with one another and together carry out the production process, referring to technology, which refers to " how".
Fifty years ago, the tools we rely upon to communicate today were only science fiction. Today, you can purchase a smartphone and make calls, surf the Web, play games, run applications and accomplish more than most speculative fiction authors dared to dream. So what's next?
In the short term, we'll likely see basic cell phones slowly fade away. As smartphones become more common and less expensive, more people will adopt them. The process is gradual. As with most new technologies, a group of enthusiastic adopters lead the way. Sometimes, the general population will follow the early pioneers -- the compact disc is a good example of such technology. In other cases, the early adopters end up owning technology that becomes obsolete without ever finding wide acceptance -- like LaserDiscs.
Smartphones seem to be in the first category. Products like the Apple iPhone and Google's Android operating system have pushed the smartphone out of the world of gadget geeks and into the mass market. In 2010, the first 4G smartphone for a major carrier in the United States made an appearance. It was the HTC EVO 4G, running on Sprint's WiMAX network [source: CNET]. The 4G network allows for faster data transfer speeds than other networks.
The Internet will continue to play an increasing role in communication. Voice over Internet protocol (VoIP) already plays a large role in several communication products and services. Sites like Facebook and Twitter allow users to communicate with networks of people. With the rise of the Web, people now have a platform from which they can address the world. In the past, only celebrities and politicians could address so many people at one time. Now, anyone with an Internet connection can do the same thing.
This may lead to changes in everything from entertainment to politics. Using the Web as a communication tool, people with aspirations may be able to find an audience more easily than ever before. It may not be long until a relatively unknown person uses the Internet to win enough support to be elected president of the United States.
