What is technology?
Technology is a term that has become deeply ingrained in our everyday lives. We often associate with gadgets, computers, or the latest scientific advancements daily. At its core, technology refers to the application of scientific knowledge for practical purposes, encompassing a wide range of tools, systems, and processes designed to solve problems and enhance human capabilities. The word technology is derived from the Greek words “techne” (art or craft) and “logos” (word or discourse). It’s not just about modern tools but encompasses processes, systems, and methods that solve problems and improve lives.
The Evolution of Technology
Technology has been a constant companion of human progress. Its journey can be divided into key eras:
