Key Differences
A part refers to a piece or segment of something that may or may not be essential to the whole's function. For example, a part of a car can be as independent as a spare tire, not necessarily required for the car's operation.
A component, on the other hand, is inherently necessary for the system's functionality. In the context of a computer, a hard drive is a component because it is essential for data storage and the computer's operation.
Parts can often be substituted or removed without disrupting the basic function of the whole. A decorative part of a piece of furniture, like a knob, can be replaced or removed without affecting the furniture's purpose.
Components are usually interdependent within systems, meaning removing or altering a component can disrupt or change the system's function. For instance, changing the graphics card in a computer can significantly alter its performance capabilities.
The distinction also lies in the level of integration. Parts might be more loosely connected to the whole, while components are often integrated into a system in such a way that they share a direct relationship with other components.
