Updated: 10/07/2019 by A communication device is a hardware device capable of transmitting an analog or digital signal over the telephone, other communication wire, or
wirelessly. A classic example of a communication device is a computer modem, which converts a computer's digital information to an analog signal for transmission over a
telephone line. Similarly, a modem receives analog signals, and converts them to digital, for processing by the computer. This process is called modulation/demodulation, from which the modem gets its name. Other examples of communication devices include a NIC (network interface card), Wi-Fi devices, and access points. Communication device examplesBelow is a full listing of all the different types of communications devices you may encounter when dealing with a computer.
Communication device errorsAny time a communication device encounters problems communicating with another device, you may encounter a communication error. Below is a list of general steps that can be verified when this error is encountered.
Why do computers need communication devices?A computer can work fine without a communication device. However, for a computer to communicate with other computers, they need a communication device. For example, for your computer to connect to the Internet to view this web page, it needs a communication device. Without a communication device, you'd have to use a sneaker net to transfer or share data between computers. Hardware terms, Modem terms, Network terms
Which of the following remote access technologies converts digital signals generated by a computer to analog signals that can be carried over standard telephone wires?Dial-up Modems: communication devices that convert a computer's digital signals into analog signals before transmission over telephone lines. A dial-up modem can be either internal or external.
Which networking device can convert the digital data into analog signal and vice versa?Modem used to converts digital signals to analog signals. It enables a computer to transmit data.
Which hardware is used to convert the digital signals of a computer to signals that can be transmitted through telephone lines?A modulator-demodulator or modem is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio.
How modems can convert data between analogue and digital?To transmit digital data, the sending modem must first modulate, or encode, a computer's digital signal into an analog signal that can travel over the phone line. The receiving modem must then demodulate, or decode, the analog signal back into a digital signal recognizable to a computer.
