it is an DAC (Digital to analogue converter
modem
You would find a digital to analog conversion taking place when you have a monitor with a VGA connection plugged into the computer. The computer would then have to convert digital signals into analog signals so the monitor could comprehend the data it is given.
Modulating. The word modem comes from Modulator/Demodulator
True, dawg.
yes
a modem
A modem converts the digital signals(used by computer)into analog signals(in telephones) and vice versa.
A microphone converts voice sound waves into electrical signals, which are then digitized by an analog-to-digital converter (ADC) to produce digital signals. These digital signals can then be processed and transmitted digitally.
speech recognition system
MOdulate/DEModulate. It converts digital computer signals into analog ones for transmission over analog telephone lines, and then converts the signal back into digital on the other end.
it is an DAC (Digital to analogue converter
A "modem" is considered a transceiver. It receives data, and sends data. But it also converts signals in the sense that it can be seen as a DAC (digital to analog converter) and a ADC (analog to digital converter). Most dialup, DSL, and cable modems are examples of that - they plug into your computer and converts from-and-to your ISP the data you're receiving and sending. The signals you send from your computer are typically digital and the modem converts them into analog ones.
no it dont
MODEM:A modem takes digital signal from computer and converts them to analog for the phone and reconverts them back
Actually you have this backwards, the telephone lines can only carry analogue signals (voice band, 20Hz to 3KHz) not digital signals.The device that converts digital signals to analogue signals for transmission over telephone lines is called a phone MoDem(this stands for phone modulator demodulator). At the opposite end of the line it of course converts the telephone analogue signals back to digital signals.
Assuming there was supposed to be a "What" at the start of that question.... The answer is a Network Interface Card (NIC).
