Detailed explanation-1: -A speaker is an output device that produces sound through an oscillating transducer called a driver. The equivalent input device is a microphone. Speakers are plugged into a computer’s sound card via a myriad of interfaces, such as a phone connector for analog audio, or SPDIF for digital audio.
Detailed explanation-2: -Speakers receive information from computers (think smartphones, laptops, tablets, etc.) and are, therefore, output devices. This information is in the form of digital audio.
Detailed explanation-3: -Headphones are a hardware device that can be plugged into a computer, laptop, smartphone, mp3 player or other device to privately listen to audio without disturbing anyone in the vicinity. They are plug-and-play devices and do not require any sort of installation before use.
