Introduction
Over thousands of years, people have invented tools and systems to meet their needs. The technological journey began with controlled fire, the wheel, and farming, and has advanced to the internet, smartphones, robots, and artificial intelligence.
Technology often develops by building on earlier knowledge and tools. For example, modern smartphones combine ideas and inventions from computing, radio communication, semiconductors, batteries, and software.
