Explanation:
A communications device is any type of hardware capable of transmitting data, instructions, and information between a sending device and a receiving device. One type of communications device that connects a communications channel to a sending or receiving device such as a com- puter is a modem. Computers process data as digital signals. Data, instructions, and information travel along a communications channel in either analog or digital form, depending on the com- munications channel. An analog signal consists of a continuous electrical wave. A digital signal consists of individual electrical pulses that represent bits grouped together into bytes.
For communications channels that use digital signals (such as cable television lines), the modem transfers the digital signals between the computer and the communications channel. If a communications channel uses analog signals (such as some telephone lines), however, the modem first converts between analog and digital signals.
The following pages describe the following types of communications devices: dial-up modems, ISDN and DSL modems, cable modems, wireless modems, network cards, wireless access points, and routers.
