Electronic parts are physical components that make up an electronic system or device. They are typically passive or active components that are used to manipulate and control the flow of electrical currents and signals.

Passive electronic parts include resistors, capacitors, inductors, diodes, and transformers. These components do not require a power source to operate, and they are used to control the flow of electrical signals, store electrical energy, and filter or amplify signals.

Active electronic parts include transistors, integrated circuits (ICs), and micro-controllers. These components require a power source to operate, and they are used to amplify, control, and manipulate electrical signals.

Other types of electronic parts include connectors, switches, sensors, relays, and motors. Connectors are used to establish electrical connections between different parts of a system, while switches are used to turn circuits on and off. Sensors are used to detect physical changes or conditions and translate them into electrical signals, and relays are used to switch high voltage or current circuits on and off. Motors are used to convert electrical energy into mechanical energy.

Overall, electronic parts are the building blocks of electronic systems, and their correct selection, integration, and operation are critical to the performance and reliability of electronic devices and equipment.
