Digital to analog converter.
An analog to digital converter and digital to analog converter are present in a computer. they serve this purpose. They are present in the form of ICs inside.
The basic elements in digital signal processing are an analog to digital converter, digital signal processor, and digital to analog converter. This process can take an analog input signal, convert it to digital for processing and offer an analog output.
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.
In digital electronics "1" generally means on," 0 " means off. This simple system is the basis of all electronics that male up computers and the uses of digital signal analysis. All the data in computers can be broken down to one and zero.

An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
Digital computers are purely digital, i.e. they use digital(electronic) means to process data. Hybrid computers conversely use both digital and analog technologies.
There are several devices called digital to analog converters for this purpose. 1s and 0s of the digital signal are used to represent the digital signal in analog form.
The set top box that your provider gives you is what converts the Digital signal to the analog signal. The digital signal is compressed at the provider and sent to the end user. The "tuner" (which can be built into a tv, a set top box or a cable card) Then decompresses the digital signal and converts it into an analog signal. There is much more to this did not know how technical you wanted your answer.
Some are, but most have been made obsolete by modern inexpensive high speed digital computers. The few that remain now are in specialized applications where speed and smooth transitionsare more important than very accurate results. Even in those places digital computers called DSPs (Digital Signal Processors) are rapidly encroaching.
