Technology is the application of knowledge to create tools and devices that improve human lives. It includes everything from telescopes and microscopes to nuclear power and computers. Technology drives the world’s most profitable industries, including information technology, entertainment, materials science, and energy. It is the key to modern conveniences such as microwave ovens, automobiles, and aircraft.
Most technological innovations spread or disappear on the basis of free-market forces. But some become issues of public debate and, occasionally, formal regulation, as is the case with contour plowing, vaccination, genetic engineering, and nuclear power plants.
Many businesses find that technology makes it easier to increase output and reduce the amount of time and labor required to do so. This is particularly true of automation technologies, which can eliminate tedious manual tasks and help to reduce the risk of error. Technology can also enable organizations to handle large volumes of data more quickly and accurately, allowing for better decision making.
In education, technology brings learning to life for students. Tablets, laptops, and VR/AR devices can make classes interesting for kids, keeping them engaged and improving their academic marks.
There are some disadvantages of technology, however. Overuse of technology can cause eye strain, back pain, and addiction, and reliance on it can lead to a lack of face-to-face communication and social skills. Online security is also an issue, with the threat of malware attacks increasing daily. In addition, the digital divide can leave some people behind as they struggle to access affordable and effective devices.
