Modem
From Simple English Wikipedia, the free encyclopedia
A Modem is a piece of computer hardware. It is used to send data from one personal computer to another personal computer. A modem both sends and receives data. The term modem stands for modulator - demodulator.
- Modulation is changing the digital data in the personal computer to analog data (audio tones or sounds) so that it can be sent.
- Demodulation is changing the analog data (audio tones) that is received over the telephone lines to digital data to be used by the computer.
Pieces of data are sent from one modem to another modem at a set speed or rate. This rate is called the baud rate.
