What Does Circuit Mean?
In the most fundamental sense, the term circuit refers to a physical or conceptual loop, often with an emphasis on resolving or closing that loop to accommodate various operations associated with electrical systems or other technologies. In IT, the term is often used when discussing the physical manufacturing of devices or pieces of hardware.
Techopedia Explains Circuit
Over time, the physical concept of an electrical circuit has developed along with various other advancements in electronics. For example, a newer type of circuit board called a printed circuit board (PCB) allows for more efficient types of mass production for hardware. These types of boards are also sometimes called etched boards because of the fine manipulation of copper or conductive materials to create core functionality.
