KOI-7
KOI-7 (КОИ-7) is a 7-bit character encoding, designed to cover Russian, which uses the Cyrillic alphabet. In Russian, KOI-7 stands for ''Kod Obmena Informatsiey, 7 bit'' (Код Обмена Информацией, 7 бит) which means "Code for Information Exchange, 7 bit". It was first standardized in GOST 13052-67 (with the 2nd revision GOST 13052-74 / ST SEV 356-76) and GOST 27463-87 / ST SEV 356-86. Shift Out (SO) and Shift In (SI) control characters In computing and telecommunications, a control character or non-printing character (NPC) is a code point in a character set that does not represent a written character or symbol. They are used as in-band signaling to cause effects other than ... are used in KOI-7, where SO starts printing Russian alphabet, Russian letters (KOI-7 N1), and SI starts printing Latin alphabet, Latin letters again (KOI-7 N0), or for lowercase and uppercase switching. This version is also known as KOI7-switched aka csKOI7switched. On ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO/IEC 646
ISO/IEC 646 ''Information technology — ISO 7-bit coded character set for information interchange'', is an International Organization for Standardization, ISO/International Electrotechnical Commission, IEC standard in the field of character encoding. It is equivalent to the Ecma International, ECMA standard ECMA-6 and developed in cooperation with ASCII at least since 1964. The first version of ECMA-6 had been published in 1965, based on work the ECMA's Technical Committee TC1 had carried out since December 1960. The first edition of ISO/IEC 646 was published in 1973, and the most recent, third, edition in 1991. ISO/IEC 646 specifies a 7-bit character code from which several national standards are derived. It allocates a set of 82 unique graphic characters to 7-bit code points, known as the ''invariant'' (INV) or ''basic character set'', including letters of the ISO basic Latin alphabet, Numerical digit, digits, and some common English language, English pun ...

KOI Character Encodings
KOI (''КОИ'') is a family of several code pages for the Cyrillic script. The name stands for ''Kod obmena informatsiey'' () which means "Code for Information Interchange". A particular feature of the KOI code pages is that the text remains human-readable when the leftmost bit is stripped, should it inadvertently pass through equipment or software that can only deal with 7 bit wide characters. This is due to characters being placed in a special order (128 codepoints apart from the Latin letter they sound most similar to), which, however, does not correspond to the alphabetic order in any language that is written in Cyrillic and necessitates the use of lookup tables to perform Sorting algorithm, sorting. These encodings are derived from ASCII on the base of some correspondence between Latin and Cyrillic (nearly phonetical), which was already used in Russian Morse code, Russian dialect of Morse code and in MTK-2 telegraph code. The first 26 characters from А (0xE1) in KOI8-R are � ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KOI-8
KOI-8 (КОИ-8) is an 8-bit character set standardized in GOST 19768-74. Маркелова Л. Н. Эксплуатация программоуправляемой вычислительной машины «Искра 226». — М.: Машиностроение, 1987. — С. 41—42. It is an extension of KOI-7 which allows the use of the Latin alphabet along with the Russian alphabet, both the upper and lower case letters; however, the letter Ёё and the uppercase Ъ are missed, the latter to avoid conflicts with the delete character (both are added in most extensions, see KOI8-B). The first 127 code points are identical to ASCII with the exception of the dollar sign $ (code point 24hex) replaced by the universal currency sign ¤. The rows x8_ and x9_ (code points 128–159) might be filled with the additional control characters from EBCDIC (code points 32–63). This standard has become the base for the later Internet standards such as KOI8-RU. Unicode is pref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
YUSCII
YUSCII is an informal name for several JUS standards for 7-bit character encoding. These include: * JUS I.B1.002 (ISO-IR-141, ISO 646-YU), which encodes Gaj's Latin alphabet, used for Serbo-Croatian and Slovenian language * JUS I.B1.003 (ISO-IR-146), which encodes Serbian Cyrillic alphabet, and * JUS I.B1.004 (ISO-IR-147), which encodes Macedonian Cyrillic alphabet. The encodings are based on ISO 646, 7-bit Latinic character encoding standard, and were used in Yugoslavia before widespread use of later CP 852, ISO-8859-2/ 8859-5, Windows-1250/ 1251 and Unicode standards. It was named after ASCII, having the first word "American" replaced with "Yugoslav": "Yugoslav Standard Code for Information Interchange". Specific standards are also sometimes called by a local name: SLOSCII, CROSCII or SRPSCII for JUS I.B1.002, SRPSCII for JUS I.B1.003, MAKSCII for JUS I.B1.004. JUS I.B1.002 is a national ISO 646 variant, i.e. equal to basic ASCII with less frequently used symbols replaced wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MTK-2
The Baudot code () is an early character encoding for telegraphy invented by Émile Baudot in the 1870s. It was the predecessor to the International Telegraph Alphabet No. 2 (ITA2), the most common teleprinter code in use before ASCII. Each Character (symbol), character in the alphabet is represented by a series of five bits, sent over a communication channel such as a telegraph wire or a radio signal by asynchronous serial communication. The symbol rate measurement is known as baud, and is derived from the same name. History Baudot code (ITA1) In the below table, Columns I, II, III, IV, and V show the code; the Let. and Fig. columns show the letters and numbers for the Continental and UK versions; and the sort keys present the table in the order: alphabetical, Gray and UK Baudot developed his first multiplexed telegraph in 1872 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dollar Sign
The dollar sign, also known as the peso sign, is a currency symbol consisting of a Letter case, capital crossed with one or two vertical strokes ( or depending on typeface), used to indicate the unit of various currency, currencies around the world, including most currencies denominated "dollar" or "peso". The explicitly double-barred sign is called cifrão in the Portuguese language. The sign is also used in several compound currency symbols, such as the Brazilian real (R$) and the United States dollar (US$): in local use, the nationality prefix is usually omitted. In countries that have other currency symbols, the US dollar is often assumed and the "US" prefix omitted. The one- and two-stroke versions are often considered mere stylistic (typeface) variants, although in some places and epochs one of them may have been specifically assigned, by law or custom, to a specific currency. The Unicode computer encoding standard defines a single code for both. In most English l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RSX-11
RSX-11 is a discontinued family of multi-user real-time operating systems for PDP-11 computers created by Digital Equipment Corporation. In widespread use through the late 1970s and early 1980s, RSX-11 was influential in the development of later operating systems such as OpenVMS, VMS and Windows NT. As the original ''Real-Time System Executive'' name suggests, RSX was designed (and commonly used) for real time use, with process control a major use. It was also popular for program development and general computing. History Name and origins RSX-11 began as a port to the PDP-11 architecture of the earlier RSX-15 operating system for the PDP-15 minicomputer, first released in 1971. The main architect for RSX-15 (later renamed XVM/RSX) was Dennis “Dan” Brevik. Commenting on the ''RSX'' acronym, Brevik says: RSX-11D and IAS The porting effort first produced small paper tape based real-time executives (RSX-11A, RSX-11C) which later gained limited support for disks (RSX-11B).

RT-11
RT-11 (Real-time 11) is a discontinued small, low-end, single-user real-time operating system for the full line of Digital Equipment Corporation PDP-11 16-bit computers. RT-11 was first implemented in 1970. It was widely used for real-time computing systems, process control, and data acquisition across all PDP-11s. It was also used for low-cost general-use computing. Features Source code RT-11 was written in assembly language. Heavy use of the conditional assembly and macro programming features of the MACRO-11 assembler allowed a significant degree of configurability and allowed programmers to specify high-level instructions otherwise unprovided for in machine code. RT-11 distributions included the source code of the operating system and its device drivers with all the comments removed and a program named "SYSGEN" which would build the operating system and drivers according to a user-specified configuration. Developer's documentation included a kernel listing that included ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
US-ASCII
ASCII ( ), an acronym for American Standard Code for Information Interchange, is a character encoding standard for representing a particular set of 95 (English language focused) printable character, printable and 33 control character, control characters a total of 128 code points. The set of available punctuation had significant impact on the syntax of computer languages and text markup. ASCII hugely influenced the design of character sets used by modern computers; for example, the first 128 code points of Unicode are the same as ASCII. ASCII encodes each code-point as a value from 0 to 127 storable as a seven-bit integer. Ninety-five code-points are printable, including digits ''0'' to ''9'', lowercase letters ''a'' to ''z'', uppercase letters ''A'' to ''Z'', and commonly used punctuation symbols. For example, the letter is represented as 105 (decimal). Also, ASCII specifies 33 non-printing control codes which originated with ; most of which are now obsolete. The control cha ...

1991
It was the final year of the Cold War, which had begun in 1947. During the year, the Soviet Union Dissolution of the Soviet Union, collapsed, leaving Post-soviet states, fifteen sovereign republics and the Commonwealth of Independent States, CIS in its place. In July 1991, India abandoned its policies of dirigism, license raj and autarky and began extensive Economic liberalisation in India, liberalisation to its economy. This increased Economy of India, GDP but also increased income inequality in India, income inequality over the next two decades. A United Nations, UN-authorized coalition of the Gulf War, coalition force from 34 nations fought against Ba'athist Iraq, Iraq, which had Invasion of Kuwait, invaded and Kuwait Governorate, annexed Kuwait in the previous year, 1990.
