Modem comes from the abbreviation MOdulator DEModulator. Modulator is part of the signal information into the carrier signal (Carrier) and is ready to be sent, while the Demodulator is a separate information signal (which contains the data or message) of the carrier signal (carrier) so that the received information can be well received. Modem is a merging both, that means the modem is a two-way communication tool. Each communication device remote two-way general use which is called the "modem", such as VSAT, Microwave Radio, and others, but the term is generally known as a modem device that is often hard to use for communication on the computer.
Data from the computer in the digital signal to the modem to be converted to analog signals. Analog signals can be transmitted through several media such as telecommunication and radio telephone.
Arriving at the destination modem, the analog signal is converted into digital signal and sent back to the computer. There are two types of modems are physical, that is an external modem and internal modem.
Type of modem
Abbreviation of Modulator and demodulator. Modem functions to include the information signal to carrier wave; Instead demodulator take back the information signal from the combined signal. Modem divided into:
1. Amplitude Modulation (AM), which is a series of electronic waves that change the amplitude of the signal amplitude in accordance with the information.
2. Frequency Modulation (FM), which is a series of electronic waves that change the frequency of changes in accordance with the frequency information signal.
3. Pulse Modulation (PM)
