Technology is the application of scientific knowledge for achieving practical goals in a reproducible way. This includes both tangible tools such as utensils or machines and intangible ones such as software.
The optimum design of technological systems must take into account many different constraints. These may include physical laws, economic factors (limited resources), political factors (local and national regulations), social factors (opposition from the public), ecological factors (likely disruption of the natural environment), or ethical factors (disadvantages to some people or risk to future generations).
Often times it is not easy to predict which technological innovations will be adopted by society or how quickly they will spread, especially in developing countries. Most of the time, however, technology moves on its own.
Technology has changed the world in a variety of ways and is changing our way of life in many other ways as well. Some of these changes can be seen in how we communicate with each other, in how we work and in the way we learn.
When it comes to education, technology can have a positive impact on students. It can help students prepare for technical working environments by teaching them computer skills and other technologies that will be useful in the job market of the future.
It can also help teachers improve their teaching by creating engaging lessons that are suited to the needs of their students. This will ultimately lead to better learning outcomes for students, and in turn better results for the school.
