Technology is the application of conceptual knowledge to achieve practical goals, especially in a reproducible way. It includes tangible tools such as utensils and machines and intangible ones like software. It is also a broad term that encompasses all human activities related to the use of tools and materials, including manufacturing, agriculture, mining, energy production, transportation, communication systems and more.
Modern technology has become a key component of everyday life, providing many advantages to humans. It has changed the world, allowing us to communicate with one another and work more efficiently. The rapid growth of technology has also raised concerns about its impact on society. For example, some experts believe that robots will soon replace human workers. Others are worried that people will become addicted to technology and suffer from addiction.
In education, advanced technology helps students of all ages to learn better. It improves their cognitive skills and makes learning more fun for them. For instance, VR/AR devices help kids to keep their attention in class and improve their academic marks. These technologies also enable students to access a huge variety of educational materials through the internet, which is very helpful in their studies.
Generally, most technological innovations spread or disappear on the basis of free-market forces. However, sometimes they become controversial and may be subject to public debate or formal regulation. This has happened with contour plowing, vaccines, genetic engineering, nuclear power plants and some other technologies. Moreover, most technological products need to be operated, maintained and occasionally repaired, which increases their overall cost. This is a major reason why some apparently promising early technologies stall midway through their development.
