What is the definition of technology?

The definition of technology is accurately captured by the notion of applying science to develop practical solutions to problems. This understanding emphasizes the role of technology as a tool that stems from scientific knowledge and principles, aiming to address real-world challenges in various fields, including medicine, engineering, information systems, and more. By utilizing scientific methodologies and insights, technology transforms theoretical discoveries into tangible applications that can improve efficiency, efficacy, and quality of life.

Exploring other choices, one option focuses on the study of physical and chemical processes, which pertains specifically to the field of science rather than the broader concept of technology. Another option relates to mathematical models for solving complex issues, which, while important in fields like data science and engineering, does not encompass the full spectrum of technology's application beyond mathematics. Finally, the exploration of human behavior in digital environments is a relevant area of study, especially in fields like psychology and user experience design, but it is too narrow to define technology as a whole. Hence, choice A is the most comprehensive and fitting definition.
