Densely packed decimal (DPD) is an efficient method for binary encoding decimal digits.. The traditional system of binary encoding for decimal digits, known as binary-coded decimal (BCD), uses four bits to encode each digit, resulting in significant wastage of binary data bandwidth (since four bits can store 16 states and are being used to store only 10), even when using packed BCD.
ASN.1 is a data type declaration notation. It does not define how to manipulate a variable of such a type. Manipulation of variables is defined in other languages such as SDL (Specification and Description Language) for executable modeling or TTCN-3 (Testing and Test Control Notation) for conformance testing.

X.690. X.690 is an ITU-T standard specifying several ASN.1 encoding formats: The Basic Encoding Rules (BER) were the original rules laid out by the ASN.1 standard for encoding data into a binary format. The rules, collectively referred to as a transfer syntax in ASN.1 parlance, specify the exact octets (8-bit bytes) used to encode data.
The algorithm, named after its inventor, Jay Earley, is a chart parser that uses dynamic programming; it is mainly used for parsing in computational linguistics. It was first introduced in his dissertation [ 2] in 1968 (and later appeared in an abbreviated, more legible, form in a journal [ 3] ).
This is a list of file signatures, data used to identify or verify the content of a file. Such signatures are also known as magic numbersor Magic Bytes. Many file formats are not intended to be read as text. If such a file is accidentally viewed as a text file, its contents will be unintelligible. However, some file signatures can be ...
Telex or TELEX ( Vietnamese: Quốc ngữ điện tín, lit. 'national language telex '), is a convention for encoding Vietnamese text in plain ASCII characters. Originally used for transmitting Vietnamese text over telex systems, it is one of the most used input method on phones and touchscreens and also computers. Vietnamese Morse code uses ...
The Encoding Control Notation (ECN) is a standardized formal language that is part of the Abstract Syntax Notation One (ASN.1) family of international standards. ECN is designed to be used along with ASN.1, and each ECN specification (a coherent set of encoding definitions) is explicitly related to a particular ASN.1 specification (a coherent set of type definitions).
