* Codec is for coding analog data into digital form and decoding it back. The digital data coded by Codec are samples of analog waves.
* Modem is for modulating digital data into analog form and demodulating it back. The analog symbols carry digital data.
What is the difference between a data card and an usb modem?
A codec is a standard for compressing and decompressing sound or video. This has nothing to do with the function of a modem.A codec is a standard for compressing and decompressing sound or video.

A coder can accept any kind of analog signal while demodulator can only accept a modulated sine wave. Then they generate the digital signal.

yes
Nothing. They are both modems (MOdulator/DEModulator).
A USB modem plugs into your USB port.A "normal" modem plugs into your RS232 port or your parallel port.
a wireless router is needed when internet modem doesn't have wireless capability.
No, the modem and codec are not exactly the functional inverse of each other. teh modem converts the digital data to analog signal by teh modulating part of it. teh demodulating part of the modem can be used to covert teh ANALOG SIGNAL to digital data....but this analog signal will be modulated analog signal. the coding part of teh codec convert teh analog signals to teh digital signal .these analog signals are pure analog signals. Hence teh codec and modem may seem as functional inverses but do not work as so due to teh fact dat the demodulating part of the modem used only the modulated analog signal and cannot process the pure analog signals .
A codec is a device or computer program capable of encoding and decoding a digital data stream or signal. The word codec is a portmanteau (a blending of two or more words) of compressor-decompressor or, more commonly, coder-decoder. The demodulator takes the wavy analog signal from the line and converts it do a digital signal. The codec puts the transmitted data together from the data the demodulator spits out. A codec is used to more effectively use the bandwidth..
Port speed is how fast the computer talks to the modem. Modem speed is how fast the modem talks across the phone line to the other modem.
An internal modem is housed within the main computer. An external modem is on the outside of the computer and connected to the computer with a cable.
