Yes, a modem (modulator-demodulator) converts digital signals from a computer into analog signals that can be transmitted over various types of networks, such as telephone lines or cable systems. It also performs the reverse function, converting incoming analog signals back into digital form for the computer. This process enables communication between digital devices and external networks.

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.
An ADC, or Analog-to-Digital Converter, is an electronic device that converts analog signals, which are continuous in nature, into digital signals, which are discrete. This conversion allows analog data, such as audio or sensor readings, to be processed by digital systems like computers and microcontrollers. ADCs are essential in various applications, including telecommunications, audio processing, and instrumentation, enabling better data manipulation and analysis in digital formats.
In Information and Communication Technology (ICT), ADC stands for Analog-to-Digital Converter. It is a device that converts analog signals, which are continuous waveforms, into digital signals, which are discrete values that can be processed by computers and digital systems. ADCs are essential in various applications, such as audio and video processing, where they allow analog inputs to be digitized for further manipulation and storage.
yes
a modem
A modem converts the digital signals(used by computer)into analog signals(in telephones) and vice versa.
The hardware used to convert the digital signals of a computer to signals that can be transmitted is called a modem (modulator-demodulator). It converts digital data from the computer into analog signals for transmission over telephone lines or cable systems. Additionally, network interface cards (NICs) and routers can also play a role in this process by facilitating data transmission over local networks and the internet.
speech recognition system
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.
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.
MODEM:A modem takes digital signal from computer and converts them to analog for the phone and reconverts them back
no it dont
Assuming there was supposed to be a "What" at the start of that question.... The answer is a Network Interface Card (NIC).
