Alt Code
On personal computers with numeric keypads that use Microsoft operating systems, such as Windows, many characters that do not have a dedicated key combination on the keyboard may nevertheless be entered using the Alt code (the Alt numpad input method). This is done by pressing and holding the key, then typing a number on the keyboard's numeric keypad that identifies the character and then releasing . MS-DOS On IBM PC compatible personal computers from the 1980s, the BIOS allowed the user to hold down the key and type a decimal number on the keypad. It would place the corresponding code into the keyboard buffer so that it would look (almost) as if the code had been entered by a single keystroke. Applications reading keystrokes from the BIOS would behave according to what action they associate with that code. Some would interpret the code as a command, but often it would be interpreted as an 8-bit character from the current code page that was inserted into the text the user was ...

Personal Computer
A personal computer, commonly referred to as PC or computer, is a computer designed for individual use. It is typically used for tasks such as Word processor, word processing, web browser, internet browsing, email, multimedia playback, and PC game, gaming. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large, costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers. The term home computer has also been used, primarily in the late 1970s and 1980s. The advent of personal computers and the concurrent Digital Revolution have significantly affected the lives of people. Institutional or corporate computer owners in the 1960s had to write their own programs to do any useful work with computers. While personal computer users may develop their applications, usually these systems run commercial software, free-of-charge software ("freeware"), which i ...

Dead Key
A dead key is a special kind of modifier key on a mechanical typewriter, or computer keyboard, that is typically used to attach a specific diacritic to a base letter (alphabet), letter. The dead key does not generate a (complete) grapheme, character by itself, but modifies the character generated by the key struck immediately after. Thus, a dedicated key is not needed for each possible combination of a diacritic and a letter, but rather only one dead key for each diacritic is needed, in addition to the normal base letter keys. For example, if a keyboard mapping (such as US international) has a dead key for the circumflex, , the character can be generated by first pressing and then . Usually, the diacritic itself can be generated as a free-standing character by pressing the dead key followed by ''space''; so a caret (free-standing circumflex) can be typed by pressing and then . Mechanical typewriters The dead key is mechanical in origin, and "dead" means without movement. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Modulo Operator
In computing and mathematics, the modulo operation returns the remainder or signed remainder of a division, after one number is divided by another, the latter being called the '' modulus'' of the operation. Given two positive numbers and , modulo (often abbreviated as ) is the remainder of the Euclidean division of by , where is the dividend and is the divisor. For example, the expression "5 mod 2" evaluates to 1, because 5 divided by 2 has a quotient of 2 and a remainder of 1, while "9 mod 3" would evaluate to 0, because 9 divided by 3 has a quotient of 3 and a remainder of 0. Although typically performed with and both being integers, many computing systems now allow other types of numeric operands. The range of values for an integer modulo operation of is 0 to . mod 1 is always 0. When exactly one of or is negative, the basic definition breaks down, and programming languages differ in how these values are defined. Variants of the definition In mathematics, the ...

Je (Cyrillic)
Je (Ј ј; italics: ) is a letter of the Cyrillic script, taken over from the Latin letter J.Maretić, Tomislav. ''Gramatika i stilistika hrvatskoga ili srpskoga književnog jezika''. 1899. It commonly represents the palatal approximant , like the pronunciation of in "hallelujah". History The Cyrillic letter ј was introduced in the 1818 Serbian dictionary of Vuk Stefanović Karadžić, on the basis of the Latin letter J. Karadžić had previously used ї instead for the same sound, a usage he took from Dositej Obradović Dositej Obradović ( sr-Cyrl, Доситеј Обрадовић, ; 17 February 1739 – 7 April 1811) was a Serbian writer, biographer, diarist, philosopher, pedagogue, educational reformer, linguist and the first minister of education of Se ...,Karadžić, Vuk Stefanović.

CP1251
Windows-1251 is an 8-bit character encoding, designed to cover languages that use the Cyrillic script such as Russian, Ukrainian, Belarusian, Bulgarian, Serbian Cyrillic, Macedonian and other languages. On the web, it is the second most-used single-byte character encoding (or third most-used character encoding overall), and most used of the single-byte encodings supporting Cyrillic. , 0.3% of all websites use Windows-1251. It's by far mostly used for Russian, while a small minority of Russian websites use it, with 94.6% of Russian (.ru) websites using UTF-8, and the legacy 8-bit encoding is distant second. In Linux, the encoding is known as cp1251. IBM uses code page 1251 (CCSID 1251 and euro sign extended CCSID 5347) for Windows-1251. Windows-1251 and KOI8-R (or its Ukrainian variant KOI8-U) are much more commonly used than ISO 8859-5 (which is used by less than 0.0004% of websites). In contrast to Windows-1252 and ISO 8859-1, Windows-1251 is not closely related to ISO 885 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pound Sterling
Sterling (symbol: £; currency code: GBP) is the currency of the United Kingdom and nine of its associated territories. The pound is the main unit of sterling, and the word '' pound'' is also used to refer to the British currency generally, often qualified in international contexts as the British pound or the pound sterling. Sterling is the world's oldest currency in continuous use since its inception. In 2022, it was the fourth-most-traded currency in the foreign exchange market, after the United States dollar, the euro, and the Japanese yen. Together with those three currencies and the renminbi, it forms the basket of currencies that calculate the value of IMF special drawing rights. As of late 2022, sterling is also the fourth most-held reserve currency in global reserves. The Bank of England is the central bank for sterling, issuing its own banknotes and regulating issuance of banknotes by private banks in Scotland and Northern Ireland. Sterling banknotes issu ...

Acute Accent
The acute accent (), , is a diacritic used in many modern written languages with alphabets based on the Latin alphabet, Latin, Cyrillic script, Cyrillic, and Greek alphabet, Greek scripts. For the most commonly encountered uses of the accent in the Latin and Greek alphabets, precomposed characters are available. Uses History An early precursor of the acute accent was the Apex (diacritic), apex, used in Latin language, Latin inscriptions to mark vowel length, long vowels. The acute accent was first used in French in 1530 by Geoffroy Tory, the royal printer. Pitch Ancient Greek The acute accent was first used in the Greek diacritics, polytonic orthography of Ancient Greek, where it indicated a syllable with a high pitch accent, pitch. In Modern Greek, a stress (linguistics), stress accent has replaced the pitch accent, and the acute marks the stressed syllable of a word. The Greek name of the accented syllable was and is (''oxeîa'', Modern Greek ''oxía'') "sharp" or "h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Windows Code Page
Windows code pages are sets of characters or code pages (known as character encodings in other operating systems) used in Microsoft Windows from the 1980s and 1990s. Windows code pages were gradually superseded when Unicode was implemented in Windows, although they are still supported both within Windows and other platforms, and still apply when Alt code shortcuts are used. Current Windows versions support Unicode, new Windows applications should use Unicode (UTF-8) and not 8-bit character encodings. There are two groups of system code pages in Windows systems: OEM and Windows-native ("ANSI") code pages. (ANSI is the American National Standards Institute.) Code pages in both of these groups are extended ASCII code pages. Additional code pages are supported by standard Windows conversion routines, but not used as either type of system code page. ANSI code page ANSI code pages (officially called "Windows code pages" after Microsoft accepted the former term being a misnomer) ...

MS-DOS
MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and re-released it in 1981 as PC DOS 1.0 for use in its PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax and capabilities. Beginning in 1988 with DR-DOS, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CP1252
Windows-1252 or CP-1252 (Windows code page 1252) is a legacy single-byte character encoding that is used by default (as the "ANSI code page") in Microsoft Windows throughout the Americas, Western Europe, Oceania, and much of Africa. Initially the same as ISO 8859-1, it began to diverge starting in Windows 2.0 by adding additional characters in the 0x80 to 0x9F ( hex) range (the ISO standards reserve this range for C1 control codes). Notable additional characters include curly quotation marks and all printable characters from ISO 8859-15. It is the most-used single-byte character encoding in the world. Although almost all websites now use the multi-byte character encoding UTF-8, , 1.1% of websites declared ISO 8859-1 which is treated as Windows-1252 by all modern browsers (as required by the HTML5 standard), plus 0.3% declared Windows-1252 directly, for a total of 1.4%.

Microsoft Windows
Windows is a Product lining, product line of Proprietary software, proprietary graphical user interface, graphical operating systems developed and marketed by Microsoft. It is grouped into families and subfamilies that cater to particular sectors of the computing industry – Windows (unqualified) for a consumer or corporate workstation, Windows Server for a Server (computing), server and Windows IoT for an embedded system. Windows is sold as either a consumer retail product or licensed to Original equipment manufacturer, third-party hardware manufacturers who sell products Software bundles, bundled with Windows. The first version of Windows, Windows 1.0, was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). The name "Windows" is a reference to the windowing system in GUIs. The 1990 release of Windows 3.0 catapulted its market success and led to various other product families ...

Code Page 437
Code page 437 ( CCSID 437) is the character set of the original IBM PC (personal computer). It is also known as CP437, OEM-US, OEM 437, PC-8, or MS-DOS Latin US. The set includes all printable ASCII characters as well as some accented letters (diacritics), Greek letters, icons, and line-drawing symbols. It is sometimes referred to as the "OEM font" or "high ASCII", or as "extended ASCII" (one of many mutually incompatible ASCII extensions). This character set remains the primary set in the core of any EGA and VGA-compatible graphics card. As such, text shown when a PC reboots, before fonts can be loaded and rendered, is typically rendered using this character set. Many file formats developed at the time of the IBM PC are based on code page 437 as well. Display adapters The original IBM PC contained this font as a 9×14 pixels-per-character font stored in the ROM of the IBM Monochrome Display Adapter (MDA) and an 8×8 pixels-per-character font of the Color Graphics Adapter ( ...
