This document discusses technology, including its definition, types, and advantages and disadvantages. Technology is defined as the application of science to solve problems through tools, machines, techniques and systems. There are two types of technology: simple technology with two or less simple machines, and advanced technology with several simple machines working together. Some key advantages are that technology reduces time to complete tasks, removes drudgery, and allows multitasking. However, disadvantages include potential negative environmental impacts, unemployment if machines replace humans, and inactivity if devices require little energy.
