  2. Wired communication - Wikipedia

    en.wikipedia.org/wiki/Wired_communication

    Wired communication refers to the transmission of data over a wire-based communication technology (telecommunication cables). Wired communication is also known as wireline communication . Examples include telephone networks , cable television or internet access , and fiber-optic communication .

  3. Transmission medium - Wikipedia

    en.wikipedia.org/wiki/Transmission_medium

    There are two main types of transmission media: guided media—waves are guided along a solid medium such as a transmission line; unguided media—transmission and reception are achieved by means of an antenna. One of the most common physical media used in networking is copper wire. Copper wire to carry signals to long distances using ...

  4. Network media - Wikipedia

    en.wikipedia.org/wiki/Network_media

    Network media refers to the communication channels used to interconnect nodes on a computer network. Typical examples of network media include copper coaxial cable , copper twisted pair cables and fiber-optic cables used in wired networks, and radio waves used in wireless data communications networks.

  5. Signal transmission - Wikipedia

    en.wikipedia.org/wiki/Signal_transmission

    In telecommunications, transmission (sometimes abbreviated as "TX") is the process of sending or propagating an analog or digital signal via a medium that is wired, wireless, or fiber-optic. [ 1 ] [ 2 ]

  6. Computer network - Wikipedia

    en.wikipedia.org/wiki/Computer_network

    The media and protocol standards that enable communication between networked devices over Ethernet are defined by IEEE 802.3. Wireless LAN standards use radio waves, others use infrared signals as a transmission medium. Power line communication uses a building's power cabling to transmit data.

  7. Telecommunications - Wikipedia

    en.wikipedia.org/wiki/Telecommunications

    Despite the modest popularity of Token Ring in the 1980s and 1990s, virtually all LANs now use either wired or wireless Ethernet facilities. At the physical layer, most wired Ethernet implementations use copper twisted-pair cables (including the common 10BASE-T networks).

  8. Data communication - Wikipedia

    en.wikipedia.org/wiki/Data_communication

    Data communication, including data transmission and data reception, is the transfer of data, transmitted and received over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires , optical fibers , wireless communication using radio spectrum , storage media and computer buses .

  9. Wireless - Wikipedia

    en.wikipedia.org/wiki/Wireless

    Wireless communication (or just wireless, when the context allows) is the transfer of information (telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves.
