What are the types of technology?
There are many types of technology, we can go one by one.

Green technology is using renewable sources like solar, wind, tidal energy to produce energy environment friendly.
Communication technology: brought revolution, communication is used for transfer of information by mobile, media, computer, email, text messages, etc. with this technology everyone is easily accessible and changed the whole scenario where it Si easy to exchange information, ideas, news, where about etc.
Construction technology: there are sky scrapers, buildings, complexes, malls and all this with this technology, where construction has reached to high limits, with technology days’ work is completed within few hours. Tractors, software for the structure of the building are used for construction of buildings. Both the commercial and the residential buildings are improved with this technology.
Assistive technology: this technology is used to provide assistance to the disabled people. Assistive is providing assistance, for the people who are impaired in speech, hearing, moving this technology gives them great assistance as speech recognition system, hearing tool, rolling chair which is very easy to handle and requires minimum effort. This has greatly helped them.

3. Saves time
4. Solves problem
5. Accessible communication
6. Cost efficiency
Disadvantages of technology

Difference between science and technology?
There is fine line between them, science is discovering new facts, studying the causes, studying nature and explaining the facts.
Technology is which solves the daily problem. It is not only results from the scientific knowledge but mathematical, and historical knowledge etc. Technology is very often a consequence of scientific knowledge.
Example: science has discovered that energy is never lost it changes its forms like how the chemical energy is converted to mechanical energy and then the technology of automobiles using the scientific knowledge.
