    The drivers of both engines held the correct token, issued from Tyer's token machines as they started their respective journeys, but the electrical circuits linking the machines at either end were also used for telephones and, together with a possible line fault caused by bad weather, this allowed the issue of two tokens at the same time.

    en.wikipedia.org/wiki/Morse_code

    Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs. [3] [4] Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy . International Morse code encodes the 26 ...

  4. Code signing - Wikipedia

    en.wikipedia.org/wiki/Code_signing

    Code signing is the process of digitally signing executables and scripts to confirm the software author and guarantee that the code has not been altered or corrupted since it was signed. The process employs the use of a cryptographic hash to validate authenticity and integrity. [1] Code signing was invented in 1995 by Michael Doyle, as part of ...

    Nvidia NVENC. Nvidia NVENC (short for Nvidia Encoder) [1] is a feature in Nvidia graphics cards that performs video encoding, offloading this compute-intensive task from the CPU to a dedicated part of the GPU. It was introduced with the Kepler -based GeForce 600 series in March 2012 (GT 610, GT620 and GT630 is Fermi Architecture).

    Detail. The PKCS #11 standard defines a platform-independent API to cryptographic tokens, such as hardware security modules (HSM) and smart cards, and names the API itself "Cryptoki" (from "cryptographic token interface" and pronounced as "crypto-key", although "PKCS #11" is often used to refer to the API as well as the standard that defines it).
