Components are the individual parts or elements that make up a larger system or object. For example, in a computer, components include the CPU, RAM, motherboard, and hard drive. Each component has a specific function that contributes to the overall operation of the system. In everyday products, components can be found in items like bicycles, where parts such as the frame, wheels, and brakes work together to create a functional vehicle. Understanding components helps in troubleshooting, maintenance, and improving the design of various systems and products.
