A modem is a device or program that enables a computer to transmit data over, for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts between these two forms.
Fortunately, there is one standard interface for connecting external modems to computers called RS-232. Consequently, any external modem can be attached to any computer that has an RS-232 port, which almost all personal computers have. There are also modems that come as an expansion board that you can insert into a vacant expansion slot. These are sometimes called onboard or internal modems.
While the modem interfaces are standardized, a number of different protocols for formatting data to be transmitted over telephone lines exist. Some, like CCITT V.34, are official standards, while others have been developed by private companies. Most modems have built-in support for the more common protocols -- at slow data transmission speeds at least, most modems can communicate with each other. At high transmission speeds, however, the protocols are less standardized.
Aside from the transmission protocols that they support, the following characteristics distinguish one modem from another:
Modem is short for MODulate/DEModulate. It modulates a signal to send across a serial wire, and demodulates the signal that comes back.In other words, a modem is both an input AND an output device.
Modem is a device which modulates and demodulates a signal.
The modem if what provides the internet, so yes, you will need the modem, the computer, and the router to have Wi-Fi for an iPod touch.
To send digital across an analog wire the signal is first laid on top of an analog signal. The process is called "modulation". It's the same thing that's done with television and radio, it's just a different type of signal.The modulated signal is sent across the wire and the MODEM at the other end receives the signal and decodes it.The process is called, "MOdulate, DEModulate, or more simply, MODEM.
If it's modulates and demodulates a signal then yes, it's a modem.
modem means modulator demodulator. it converts digital signal to analog signal. it is use to transmit computer signal (digital signal) over the telephone line to communicate to other computers. modem converts the computer digital signal into frequency (analog signal) so that it can transmit over the telephone line and at the receiving end the modem converts the analog signal back to digital for the receiving computer to understand it.
A modem converts a digital signal into an analog signal. Allowing us to use a phone line as a transmission medium.
You can use a wireless modem if there is an unlocked signal available.
Demodulation the opposite is Modulation And when you put them together you get MODEM Modulation/Demodulation = MODEM
MODEM stands for modulator/demodulator. Outgoing it modulates a carrier wave with information and transmits this data on a wire or through the air. When it receives a modulated signal it demodulates the signal and separates out the information.
Umm yeah GET ROAD RUNNER
Modem is a what not a who. A computer modem is a device that uses an analog carrier signal to encode digital information. The modem is how you connect to dial up Internet.
