A machine is a mechanical device that is used to make human work easier and faster. In the modern era, machines have become an integral part of our daily lives. Machines are used everywhere from home to industry, agriculture, transportation, communication, and medicine. Machines reduce human labor and speed up work. From simple to complex, small to large, each machine has its specific function. For example, a clock tells time, establishes telephone communication, and a computer stores and analyzes information.
The use of machines in industry has increased productivity many times over. In agriculture, tractors and harvesting machines have freed people from labor. Power or fuel is required to run machines, which can be human power, electricity, or any other power. In today's technology-dependent world, the importance of machines is immense. It is difficult to imagine modern civilization without machines. Therefore, machines play an important role in human development and will continue to do so in the future.
