    An INI file is a configuration file for computer software that consists of plain text with a structure and syntax comprising key–value pairs organized in sections. [1] The name of these configuration files comes from the filename extension INI, short for initialization, used in the MS-DOS operating system which popularized this method of software configuration.

  5. Initialization (programming) - Wikipedia

    en.wikipedia.org/wiki/Initialization_(programming)

    Initialization is done either by statically embedding the value at compile time, or else by assignment at run time. A section of code that performs such initialization is generally known as "initialization code" and may include other, one-time-only, functions such as opening files; in object-oriented programming , initialization code may be ...

  6. Manchester code - Wikipedia

    en.wikipedia.org/wiki/Manchester_code

    In telecommunications and data storage, Manchester code (also known as phase encoding, or PE) is a line code in which the encoding of each data bit is either low then high, or high then low, for equal time. It is a self-clocking signal with no DC component. Consequently, electrical connections using a Manchester code are easily galvanically ...

    A fill device or key loader is a module used to load cryptographic keys into electronic encryption machines. Fill devices are usually hand held and electronic ones are battery operated. Older mechanical encryption systems, such as rotor machines, were keyed by setting the positions of wheels and plugs from a printed keying list. Electronic ...

    Block diagram of count key data track format used on IBM mainframe computers beginning with S/360 shipment in 1965. The reason for CKD track format is to allow data field lengths to vary, each recorded block of data on a DASD track, called a record has an associated count field which identifies the record and indicates the size of the key, if used (user-defined up to 255 bytes), and the size ...
