Tools and machinery are essential devices used to perform specific tasks, often making work easier and more efficient. Tools can be simple, like hammers and screwdrivers, or more complex, such as power drills and saws. They are typically handheld and require human effort to operate. Machinery, on the other hand, refers to larger, often powered equipment designed to automate tasks. Examples include tractors for farming and conveyor belts in factories. These machines can perform repetitive tasks quickly and with precision, significantly increasing productivity in various industries.
