Detailed explanation-1: -These include computers and microprocessors as they are often used to detect a signal from a sensor. The table below lists a number of OUTPUT devices. These are usually devices such as motors or buzzers. For example, the output to an alarm system will be a buzzer or siren sounding.
Detailed explanation-2: -Output devices A heater: The resistance wire in a heater gets hot when electrical current flows throw it. A buzzer or a beeper produces sound as an output. An electric motor: It converts electrical energy into rotational movement.
Detailed explanation-3: -Most control devices either open or close the path of the circuit. Light switches, thermostats, and time clocks are examples of common control devices found in circuits. A protective device is used to protect either the load or the path from excessive heat from overcurrent or overvoltage conditions.
Detailed explanation-4: -Sensors are used to measure physical quantities such as temperature, light, pressure, sound, and humidity. They send signals to the processor . For example: a security alarm system may have an infrared sensor which sends a signal when the beam is broken.
