ISO Keyboard
ISO/IEC 9995 ''Information technology — Keyboard layouts for text and office systems'' is an ISO/IEC standard series defining layout principles for computer keyboards. It does not define specific layouts but provides the base for national and industry standards which define such layouts. The project of this standard was adopted at ISO in Berlin in 1985 under the proposition of Dr Yves Neuville. The ISO/IEC 9995 standard series dates to 1994 and has undergone several updates over the years. Parts The ISO/IEC 9995 standard series currently (as of September 2015) consists of the following parts: * ISO/IEC 9995-1:2009 ''General principles governing keyboard layouts'' * ISO/IEC 9995-2:2009 ''Alphanumeric section'' with Amendment 1 (2012) ''Numeric keypad emulation'' * ISO/IEC 9995-3:2010 ''Complementary layouts of the alphanumeric zone of the alphanumeric section'' * ISO/IEC 9995-4:2009 ''Numeric section'' * ISO/IEC 9995-5:2009 ''Editing and function section'' * ISO/IEC 9995-7:2009 ...

International Organization For Standardization
The International Organization for Standardization (ISO ) is an international standard development organization composed of representatives from the national standards organizations of member countries. Membership requirements are given in Article 3 of the ISO Statutes. ISO was founded on 23 February 1947, and (as of November 2022) it has published over 24,500 international standards covering almost all aspects of technology and manufacturing. It has 809 Technical committees and sub committees to take care of standards development. The organization develops and publishes standardization in all technical and nontechnical fields other than electrical and electronic engineering, which is handled by the IEC.Editors of Encyclopedia Britannica. 3 June 2021.International Organization for Standardization" ''Encyclopedia Britannica''.

Kana
The term may refer to a number of syllabaries used to write Japanese phonological units, morae. Such syllabaries include (1) the original kana, or , which were Chinese characters (kanji) used phonetically to transcribe Japanese, the most prominent magana system being ; the two descendants of man'yōgana, (2) , and (3) . There are also , which are historical variants of the now-standard hiragana. In current usage, 'kana' can simply mean ''hiragana'' and ''katakana''. Katakana, with a few additions, are also used to write Ainu. A number of systems exist to write the Ryūkyūan languages, in particular Okinawan, in hiragana. Taiwanese kana were used in Taiwanese Hokkien as glosses (ruby text or ''furigana'') for Chinese characters in Taiwan when it was under Japanese rule. Each kana character (syllabogram) corresponds to one sound or whole syllable in the Japanese language, unlike kanji regular script, which corresponds to a meaning (logogram). Apart from the five vowels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Numeric Keypad
A numeric keypad, number pad, numpad, or ten key, is the palm-sized, usually-17-key section of a standard computer keyboard, usually on the far right. It provides calculator-style efficiency for entering numbers. The idea of a 10-key number pad cluster was originally introduced by Tadao Kashio, the developer of Casio electronic calculators. The numpad's keys are digits to , (addition), (subtraction), (multiplication) and (division) symbols, (decimal point), , and keys.numeric keypad' at FOLDOC Laptop keyboards often do not have a numpad, but may provide numpad input by holding a modifier key (typically labelled ) and operating keys on the standard keyboard. Particularly large laptops (typically those with a 15.6 inch screen or larger) may have space for a real numpad, and many companies sell separate numpads which connect to the host laptop by a USB connection (many of these also add an additional spacebar off to the side of the zero where the thumb is locat ...

Space (punctuation)
In writing, a space () is a blank area that separates words, sentences, syllables (in syllabification) and other written or printed glyphs (characters). Conventions for spacing vary among languages, and in some languages the spacing rules are complex. Inter-word spaces ease the reader's task of identifying words, and avoid outright ambiguities such as "now here" vs. "nowhere". They also provide convenient guides for where a human or program may start new lines. Typesetting can use spaces of varying widths, just as it can use graphic characters of varying widths. Unlike graphic characters, typeset spaces are commonly stretched in order to align text. The typewriter, on the other hand, typically has only one width for all characters, including spaces. Following widespread acceptance of the typewriter, some typewriter conventions influenced typography and the design of printed works. Computer representation of text facilitates getting around mechanical and physical limitations su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 646
ISO/IEC 646 is a set of ISO/IEC standards, described as ''Information technology — ISO 7-bit coded character set for information interchange'' and developed in cooperation with ASCII at least since 1964. Since its first edition in 1967 it has specified a 7-bit character code from which several national standards are derived. ISO/IEC 646 was also ratified by ECMA as ECMA-6. 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. Characters in the ISO/IEC 646 Basic Character Set are ''invariant characters''. Since that portion of ISO/IEC 646, that is the ''invariant character set'' shared by all countries, specified only those letters used in the ISO basic Latin alphabet, countries using additional letters needed to create national variants of ISO/IEC 646 to be able to use their native scripts. Since transmission and storage of 8-bit codes was not standard at the time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin Alphabet
The Latin alphabet or Roman alphabet is the collection of letters originally used by the ancient Romans to write the Latin language. Largely unaltered with the exception of extensions (such as diacritics), it used to write English and the other modern European languages. With modifications, it is also used for other alphabets, such as the Vietnamese alphabet. Its modern repertoire is standardised as the ISO basic Latin alphabet. Etymology The term ''Latin alphabet'' may refer to either the alphabet used to write Latin (as described in this article) or other alphabets based on the Latin script, which is the basic set of letters common to the various alphabets descended from the classical Latin alphabet, such as the English alphabet. These Latin-script alphabets may discard letters, like the Rotokas alphabet, or add new letters, like the Danish and Norwegian alphabets. Letter shapes have evolved over the centuries, including the development in Medieval Latin of lower-case, fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Language
is spoken natively by about 128 million people, primarily by Japanese people and primarily in Japan, the only country where it is the national language. Japanese belongs to the Japonic or Japanese- Ryukyuan language family. There have been many attempts to group the Japonic languages with other families such as the Ainu, Austroasiatic, Koreanic, and the now-discredited Altaic, but none of these proposals has gained widespread acceptance. Little is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century AD recorded a few Japanese words, but substantial Old Japanese texts did not appear until the 8th century. From the Heian period (794–1185), there was a massive influx of Sino-Japanese vocabulary into the language, affecting the phonology of Early Middle Japanese. Late Middle Japanese (1185–1600) saw extensive grammatical changes and the first appearance of European loanwords. The basis of the standard dialect moved f ...

Hiragana
is a Japanese syllabary, part of the Japanese writing system, along with ''katakana'' as well as ''kanji''. It is a phonetic lettering system. The word ''hiragana'' literally means "flowing" or "simple" kana ("simple" originally as contrasted with kanji). Hiragana and katakana are both kana systems. With few exceptions, each mora in the Japanese language is represented by one character (or one digraph) in each system. This may be either a vowel such as ''"a"'' (hiragana あ); a consonant followed by a vowel such as ''"ka"'' (か); or ''"n"'' (ん), a nasal sonorant which, depending on the context, sounds either like English ''m'', ''n'' or ''ng'' () when syllable-final or like the nasal vowels of French, Portuguese or Polish. Because the characters of the kana do not represent single consonants (except in the case of ん "n"), the kana are referred to as syllabic symbols and not alphabetic letters. Hiragana is used to write ''okurigana'' (kana suffixes following a kanji ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Katakana
is a Japanese syllabary, one component of the Japanese writing system along with hiragana, kanji and in some cases the Latin script (known as rōmaji). The word ''katakana'' means "fragmentary kana", as the katakana characters are derived from components or fragments of more complex kanji. Katakana and hiragana are both kana systems. With one or two minor exceptions, each syllable (strictly mora) in the Japanese language is represented by one character or ''kana'' in each system. Each kana represents either a vowel such as "''a''" (katakana ア); a consonant followed by a vowel such as "''ka''" (katakana カ); or "''n''" (katakana ン), a nasal sonorant which, depending on the context, sounds either like English ''m'', ''n'' or ''ng'' () or like the nasal vowels of Portuguese or Galician. In contrast to the hiragana syllabary, which is used for Japanese words not covered by kanji and for grammatical inflections, the katakana syllabary usage is comparable to italics in En ...

Language Input Keys
Language input keys, which are usually found on Japanese and Korean keyboards, are keys designed to translate letters using an input method editor (IME). On non-Japanese or Korean keyboard layouts using an IME, these functions can usually be reproduced via hotkeys, though not always directly corresponding to the behavior of these keys. Keys for Japanese Keyboards The OADG 109A and older 109 keyboard layouts which are the standard for Microsoft Windows have five dedicated language input keys: * halfwidth/fullwidth/kanji (hankaku/zenkaku/kanji ) at the top left key of the keyboard; * alphanumeric (eisū ), combined with non-language specific key ; * non-conversion (muhenkan ), on the left of the space bar; * conversion (henkan ), on the right of the space bar; * katakana/hiragana/rōmaji (), on the right of the space bar, next to . Apple keyboards designed for Mac OS X have two language input keys: alphanumeric () and kana (). The keyboards for NEC PC-9800 series, which was dom ...

Space Bar
The space bar is on the bottom center of the keyboard The space bar, spacebar, blank, or space key is a key on a typewriter or alphanumeric keyboard in the form of a horizontal bar in the lowermost row, significantly wider than all other keys. Its main purpose is to conveniently enter a space, e.g., between words during typing. History Originally, (on early writers dating back to the late 19th century) the "bar" was literally a metal bar running across the full width of the keyboard (or even wider, and even surrounding it) that triggered the carriage advance without also firing any of the typebars towards the platen. Later examples gradually shrank and developed into their current more ergonomic form as a wide, centrally located but otherwise apparently normal "key", as typewriter (and computer) keyboards began to incorporate additional function keys and were more deliberately "styled". Although it varies by keyboard type, the space bar usually lies between the Alt keys (or Com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
