What Is A Modem?
Computers send lots of type of information back and forth when they are connected. We often say this information is “digital” because it’s made up of digits. Billions of ones and zeros get sorted into words, sounds, images and everything else you see on your screen.
We use a modem to transmit data between computers in different ways. For example, modems often used to connect over phone lines and transmitted in different sound frequencies. More recently, fiber-optic modems use light, which is much faster, instead.
The name modem comes from the term modulator-demodulator. Its job is to change the digital information to transmit, and then receive information to put back into digital form.
If you’d like to visualize this a little better, check out this example of a typical dial-up modem’s different frequencies. Those frequencies represent different types of information.
Take the number 200. In binary, it would be written 11001000, but we can modulate that number to make it easier to share. Instead of ones and zeros, try telling a friend the number using “beep” for one and “boop” for zero. You can substitute any type of noise (or even dance moves) that you’d like. See if you can correctly share your number with a friend.
