Technology is the application of scientific knowledge for practical aims. It uses the results of science to create tools, systems and processes that improve human environments. It draws on a broad range of science, engineering, mathematical, linguistic, and historical knowledge.
A key advantage of technology is that it allows people to communicate with each other across long distances. It also makes it easier for companies to sell their products worldwide and for consumers to find them. Technology is also making machines smarter. This is helping some jobs be done by robots, freeing humans to do more complex tasks.
Modern communication technologies like television, radio, telephone, and the Internet allow people to exchange information quickly and easily. Computers and smartphones are examples of technological advances that have made it possible to share information electronically.
Another benefit of technology is that it helps people learn more efficiently. Educational technology includes devices that help students learn, such as projectors and smartboards. Students can use them to follow classroom lectures, research topics, and write papers. This technology is also used by students who are studying abroad because it can help them understand the culture of their host country more easily.
People who are addicted to their gadgets can suffer from many health issues, including obesity and sleep problems. They can also lose their social skills.
