Why is a modem is both input and output devices?

Answer 1

A modem is considered an output /input devices because a modem sends and receives data at the same time. For example,whenever you are Surfing, you send a web - page request that its info out or output. When you receive or access web pages which would entail an input device.

Answer 3

This shouldn't be a puzzle to you. You can talk and listen at the same time, using your voice to talk and your ears to listen. Your body has an input channel and an output channel. So does a MODEM.

A modem allows 2 devices such as computers or terminals to communicate with each other through a telephone line.

The telephone line is designed for audio (talking) only and in order for computing equipment to use a phone line, the modem converts information from the computer in the form of 0 and 1 bits to audio (sound) signals.

The name "MODEM" stands for MODulator/DEModulator where each modem modulates the information into sounds to be sent through the phone line and demodulates the received sounds back to computer bits.

By convention, the calling (originating) modem uses one pair of sounds (a sound for 0 and a sound for a 1) to send data. The called modem receives those sound as incoming data and uses a separate pair of sound frequencies to send information to the originating modem. These are the beeping noises you might hear over the phone line when using a mode.

Answer 4

The name modem is short for MOdulator-DEModulator. To modulate means to put a signal onto a carrier wave so it can be transmitted. To demodulate means to extract the original signal from a carrier wave. Put another way, a modem converts digital signal data into sound waves to send them to another computer, and receives those sound waves from another computer and coverts them back into digital data.

Answer 5

a modem do modulation(analog to digital) and demodulation(digital to analog) both.so it acts as an input device and as an output device

Answer 6

Modem stands for MOdulater DEMdulator. It sends pulses through the phone line, converted from the 1001010 of a computer, and visa versa. This allows the internet.
