Technology is a broad term that can refer to a wide range of tools and machines that may be used to solve real-world problems. These tools can be as simple as a crowbar or as complex as a particle accelerator. It can also include virtual technologies such as computer software and business methods.
In a more specific way, technology is often described as the application of scientific knowledge to the practical aims of human life or to the change and manipulation of the human environment. This can be accomplished by using machines, equipment, or materials such as metals, plastics, or electronics. It can also be achieved through the use of new systems, techniques, or processes such as computer simulations and artificial intelligence.
Education is one of the fields that uses technology extensively. The development of educational technology has allowed for many changes, including the ability to provide differentiated instruction to students, to allow students to work at their own pace and to connect with instructors remotely. The use of technology in education also prepares students for technical working environments.
However, technology can have negative effects on society. For example, people who are engrossed in their devices can be distracted from other tasks and may neglect to take care of themselves. They can also suffer from health issues like eye strain and obesity. Privacy and security are other concerns associated with technology. In addition, overuse of technology can lead to addiction.
