What is an Input Device? Function

Input devices are those that provide the input signals or input data from the outside to inside into a system or processing device. The main function of input devices is to collect data from the outside world and transfer it into the system or processor. Input devices are consist of so many sensors, transducers, and mechanical arrangements for the gathering of signals. For example, a microphone uses a transducer either a diaphragm or a capacitive transducer to convert the real voice into electrical. So the input device also does the energy conversion process to gather the data.

The input devices can be divided according to different types of factors such as mode of input, nature of input, power supply requirements. according to the power supply requirement, the input devices can be two types such as - active and passive. The active input devices do not need an external power supply for their working mechanism such as a microphone, switches, etc. The input devices having piezoelectric transducer also does not require an external power supply, they can generate power supply itself.

The passive input devices are those which require an external power supply for their working. For example digital keyboards, scanners are that they required a power supply. When they are connected to a processing device or any system they take the power supply from that processing device and generate an input signal according to the changes in the real world then send it to the processor.


What is an Output Device? Function

Output devices are those which take or receive the signals from a processing device or any system and deliver it to the real world by making it the proper understanding to the user. The main function of the output devices is to receive the signal and convert it to deliver the real world. For example, a speaker receives the audio signal from an amplifier or computer in the form of electrical energy and converts it into sound energy to deliver the real world, so we can listen to the audio or music.

An output device provides signals or data in different formats such as the speaker providing in the form of sound energy, a monitor providing in the visual format, the printer printing the virtual objects into real objects, and the GPS(Global Positioning System) provides in the form of data. The main difference between an input and output device is the input device sends the signal to the processor whereas the output device receives that data pr signal from the processor.
