MODEM Stands for MOdulator DEModulator.
It acts both as an input & output (SIGNAL) as it converts incoming analog signals to digital and viceversa.

Outgoing - while uploading.
Devices for communication between computers, such as modems and network cards , typically serve for both input and output. Also, a touch screen can be considered as an input and output. 1.Modems 2.Network Cards. 3.Touch Screen. 4.Headsets. 5.Facsimile (Fax). 6.Audio Cards/Sound Card.
A serial port is neither strictly an input device nor an output device; rather, it is a communication interface that can handle both input and output data. It allows for the transmission of data between a computer and peripheral devices, such as modems or printers. Depending on the direction of data flow, a serial port can function as an input, output, or both simultaneously.

Neither, it is not classified under input or output. It has its own identity
The devices that perform both input AND output operations are referred to as I/O (input/output) devices and their operations are called I/O operations. Examples of common input and output components are disk drives and modems. A touch screen monitor on an ATM or a video game controller that shakes when the player is hit can both be considered an I/O device. A CD or DVD burner would also be an I/O device, since it can both read and write data to discs.
What is the difference between output and input?If you sing into a microphone you can hear the microphone's output.Sound coming out of the power amp to the speakers.That is the input of the loudspeaker.Do you see the difference?Your voice is the microphone's input. Its output is electrical impulses that are input to the amplifier. The amplified impulses are the output of the amplifier and input to the speaker. Sound waves are output of the speaker and input to your ears.
The formula for work exerted by each simple machine is: Lever: Work = Input force × Input distance = Output force × Output distance Inclined plane: Work = Input force × Input distance = Output force × Output distance Pulley: Work = Input force × Input distance = Output force × Output distance Wheel and axle: Work = Input force × Input radius = Output force × Output radius Wedge: Work = Input force × Input distance = Output force × Output distance Screw: Work = Input force × Input distance = Output force × Output distance
