Components are the individual parts that make up a larger system, particularly in electronics. They can include items like resistors, capacitors, and integrated circuits, each serving a specific function within a device. Understanding these components is essential for designing and troubleshooting electronic circuits. In addition to electronics, the term 'components' can also refer to parts of a larger system in various fields, such as software development, where modules and libraries are considered components. Each component plays a crucial role in ensuring the overall functionality and efficiency of the system it belongs to.
