  2. 8b/10b encoding - Wikipedia

    en.wikipedia.org/wiki/8b/10b_encoding

    Because 8b/10b encoding uses 10-bit symbols to encode 8-bit words, some of the possible 1024 (10 bit, 2 10) symbols can be excluded to grant a run-length limit of 5 consecutive equal bits and to ensure the difference between the count of zeros and ones to be no more than two. Some of the 256 possible 8-bit words can be encoded in two different ...

  4. Cryptographic key types - Wikipedia

    en.wikipedia.org/wiki/Cryptographic_key_types

    This page shows the classification of key types from the point of view of key management. In a key management system, each key should be labeled with one such type and that key should never be used for a different purpose. According to NIST SP 800-57 (Revision 4) the following types of keys exist: [2] [1] [3] Private signature key

  5. PETSCII - Wikipedia

    en.wikipedia.org/wiki/PETSCII

    PETSCII (PET Standard Code of Information Interchange), also known as CBM ASCII, is the character set used in Commodore Business Machines' 8-bit home computers.. This character set was first used by the PET from 1977, and was subsequently used by the CBM-II, VIC-20, Commodore 64, Commodore 16, Commodore 116, Plus/4, and Commodore 128.

  6. Num Lock - Wikipedia

    en.wikipedia.org/wiki/Num_lock

    Num Lock would be used to select between the two functions. On some laptop computers, the Num Lock key is used to convert part of the main keyboard to act as a (slightly skewed) numeric keypad rather than letters. On some laptop computers, the Num Lock key is absent and replaced by the use of a key combination. [1]

    Locking your keys in your car is never fun—especially when you’re running late. Here’s a tip: Keep a roll of string around, and you’ll never have to cash out for a locksmith again. Don’t ...

  8. 6b/8b encoding - Wikipedia

    en.wikipedia.org/wiki/6b/8b_encoding

    In telecommunications, 6b/8b is a line code that expands 6-bit codes to 8-bit symbols for the purposes of maintaining DC-balance in a communications system. [1] The 6b/8b encoding is a balanced code-- each 8-bit output symbol contains 4 zero bits and 4 one bits. So the code can, like a parity bit, detect all single-bit errors.

  9. Mnemonics (keyboard) - Wikipedia

    en.wikipedia.org/wiki/Mnemonics_(keyboard)

    In Microsoft Windows, mnemonics are called "Access keys". [1] In Web browsers, Access keys may or may not be engaged by the Alt key. Using mnemonics is limited to entering the underlined character with a single key stroke; for this reason, localized versions of software omit letters with diacritics that need to be input via an extra dead key ...
