  2. 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 ...

  3. Personal area network - Wikipedia

    en.wikipedia.org/wiki/Personal_area_network

    A wireless personal area network (WPAN) is a PAN carried over a low-powered, short-distance wireless network technology such as IrDA, Wireless USB, Bluetooth, NearLink or Zigbee. The reach of a WPAN varies from a few centimeters to a few meters. WPANs specifically tailored for low-power operation of the sensors are sometimes also called low ...

    Claude Shannon's diagram of a general communications system An electronic communications system using electronic signals. A communications system or communication system is a collection of individual telecommunications networks systems, relay stations, tributary stations, and terminal equipment usually capable of interconnection and interoperation to form an integrated whole.

  6. Joint Direct Attack Munition - Wikipedia

    en.wikipedia.org/wiki/Joint_Direct_Attack_Munition

    The Joint Direct Attack Munition (JDAM) is a guidance kit that converts unguided bombs, or "dumb bombs", into all-weather precision-guided munitions (PGMs). JDAM-equipped bombs are guided by an integrated inertial guidance system coupled to a Global Positioning System (GPS) receiver, giving them a published range of up to 15 nautical miles (28 km).

  7. Wire-guided missile - Wikipedia

    en.wikipedia.org/wiki/Wire-guided_missile

    A wire-guided missile is a missile that is guided by signals sent to it via thin wires connected between the missile and its guidance mechanism, which is located somewhere near the launch site. As the missile flies, the wires are reeled out behind it (command guidance). This guidance system is most commonly used in anti-tank missiles, where its ...

  8. 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.

  9. Guided bomb - Wikipedia

    en.wikipedia.org/wiki/Guided_bomb

    This structure had previously been the target of 800 American sorties [5] (using unguided weapons) and was partially destroyed in each of two successful attacks, the other being on 27 April 1972 using Walleyes. That first mission also had laser-guided weapons, but bad weather prevented their use.
