What does the term 'electronics' refer to?

The term 'electronics' specifically refers to the control of systems using electrical signals. This encompasses a broad range of technologies and applications where electrical signals are utilized to manage and operate devices and systems.

Electronics involves the manipulation of electric currents through various components such as diodes, transistors, and integrated circuits to produce a desired outcome, such as control signals or communication functions. This is evident in devices like computers, smartphones, and communication systems, where the arrangement and behavior of electronic components enable the operation of complex systems.

In contrast, the focus on only the study of electrical components or merely the examination of electric voltages does not fully capture the essence of electronics. Additionally, while programming electrical devices relates to the operation of some electronic systems, it is a subset of the broader field, which primarily emphasizes how electrical signals are used to control systems.
