  • ENIAC

    Acronym for Electronic Numerical Integrator And Computer, the first operational electronic digital computer in the U.S., developed by Army Ordnance to compute World War II ballistic firing tables. The ENIAC, weighing 30 tons, using 200 kilowatts of electric power and consisting of 18,000 vacuum tubes, 1,500 relays, and hundreds of thousands of resistors, capacitors, and […]

  • scattering

    In fiber optic transmissions, scattering is the loss of signal caused by the diffusion of a light beam, where the diffusion itself is caused by microscopic variations in the transmission medium. Scattering typically happens when a light signal hits an impurity in the fiber.

  • NNTP

    Short for Network News Transfer Protocol, the protocol used to post, distribute, and retrieve USENET messages. The official specification is RFC 977. NNTP replaced UUCP, the original USENET protocol.

  • 802.11ac (Gigabit Wi-Fi)
