MP3 Players are not an Input Device nor an Output Device but in itself a Small Computer. MP3 Players generally have USB as Input Port for Copying\Deleting Songs, 3.5mm Audio Jack as Output Port to listen, Flash Storage to store Music, A Small Processing Chip and maybe a small LCD Display to select Songs & Audio Settings. MP3 Players are Small Portable & Handheld Music Playing Stereos connected to Headphones or external Speakers to listen to Audio generally in MP3 and WMA format.
It is output (read more below)
An MP3 player uses the file.mp3 (a song for example) as its input.
It then decodes (decompresses) this as an MP3 file is a compressed file.
The resulting decoded data is then used as it's output, usually sent to a speaker with the help of a digital to analog converter and an amplifier.
A MP3 recorder would do the process in reverse and the sound would be its input and the resulting MP3 file would be it's output.

An MP3 Digital Player is an 'Output' device. Basically, anything that is a 'Player' is sending 'out' a signal like music, video and so on, to an audio source. The audio source could be headphones, and amp/speaker set up, a TV and so on. Your smart phone and tablet (iPad Galaxy etc) 'Output' their sounds to their internal speakers and screen or headphones.
You can also 'Input' some devices into a Player. For example, some MP3 players, smart phones, tablets, computers and so on may have a Microphone Input so you can record voice, instruments, sing along to backing tracks and so on.

Because with most MP3 players you can only "output" media. As opposed to "input" meaning it can receive, such as a microphone, or a camera.
A monitor is first and foremost an Output Device because it displays information already held in the computer. Touchscreen monitors that allow you to input information or to use navigational features such as menus, icons and so on are also Input Devices. Another example of a device that is both an input and output device is a joystick with Force Feedback technology.
speaker is an output device. It is said as an output device because, most of the speakers are used to hear audio/sounds. The inputs to hear sound from a speaker can be > power/electricity > a device to play the sound (that may be a mic, vcd, dvd, mp3 player or even your computer)
A song is an input. When you select a song to play, the MP3 file is decoded, and this data is sent to the speaker to be used as the output.
No, an input device is something that carries data into something. In this case, the processor. This incoming information doesn't have to be analog information coming from a human, but it sometimes is. (E.G. a computer mouse, a computer keyboard) It also could be another electronic device interacting with the computer. (E.G. a flash drive, a phone, an mp3 player). For a better way of understanding this, here is how input and output work: Input -> Processor -> Output Keyboard -> Computer -> Monitor
I'm speaking with a little knowlege from djing so what im saying is based on my station (aux) auxiliary input is where I can plug my turntables or any basic sound device onto the music board, and mp3 input is only for your mp3, maybe tell me what device your talking about and I can be more relevant
Output devices are anything that send signals to other devices. A portable MP3 player, for instance, outputs music to your headphones. Your headphones plug into the "input" jack of the MP3 player because they receive a "signal" from the MP3 player in the form of music. Other examples of output devices would be video cards, keyboards, mice, gaming controlers, or dvd/blu-ray players. These all send signals to be used by other devices but do not receieve signals back from those devices.
In ways of features/programs, no. But in reality, it is a computer. It uses a processor and monitor, plus an input device, and an output device. Add the computing power and memory, and it's a computer. Just a really, really, REALLY small one. So in a way, it is a personal computer.
Every designer of MP3 Players has a USB hack output, however the input to the machine is different for every machine. There is no one standard USB jack.
Easily? No. To do so you setup your turntable so that the speaker output goes into your computer aux input and you record it with Audicity (that's what I used when I did mine) and then convert the output from WAV to mp3. It's a slow process but worth it depending on what music you have.
