Transmission (data communications)

Transmission is the transfer of information between devices through a communication channel. It encodes information as signals that travel over wired or wireless media.

Digital modulation: Digital modulation represents digital data by varying a carrier signal's amplitude, frequency, or phase. It maps transmitted bits onto signals suited to a physical channel.
Data: Data are representations of facts, measurements, or other information that can be stored or processed. Transmission carries data as encoded signals rather than as abstract meaning.
Ethernet: Ethernet is a family of wired networking technologies standardized for local area networks. It carries data between devices over wired network links.
Serial communication: Serial communication sends data symbols sequentially over a communication link. It contrasts with parallel transmission, which sends multiple symbols simultaneously.
Line coding: Line coding maps digital data to signal patterns for transmission over a physical medium. It shapes bit patterns into electrical or optical signals on wired links.
Signal (electronics): An electronic signal is a time-varying physical quantity that conveys information or represents a system's state. Signals are the physical forms that carry transmitted information through channels.
Wi-Fi: Wi-Fi is a family of wireless networking standards based on IEEE 802.11. It transmits network data by radio between devices and access points.
Parallel communication: Parallel communication sends multiple data bits simultaneously across separate signal paths. It contrasts with serial links, which send symbols sequentially on fewer paths.
Communication channel: A communication channel is a medium or path through which signals carry information between a sender and receiver. It is the path whose limits and distortions shape every transmission.
Bit: A bit is a binary digit, taking one of two values, commonly represented as 0 or 1. Digital transmissions commonly encode information as sequences of bits.
