ASCII The, characters: description, miiska of codes iyo noocyada

Sida la og yahay, computer ka qabaneysa warbixin qaab binary, waxaa soo bandhiga sida isku xigxiga oo ka mid ah kuwa iyo eber. Si aad u tarjumaan macluumaadka qaab ku haboon isticmaalka aadanaha, isku xigxiga kasta u gaar ah tirooyinka marka bandhigeen badalay qof u dhigma.

Mid ka mid ah hababka xiriir codes binary daabacayo iyo jilayaal gacanta waa ASCII.

Heerka hadda ee horumarinta technology computer user uusan baahan yihiin inay ogaadaan code for calaamad kasta oo gaar ah. Si kastaba ha ahaatee, faham guud oo ku saabsan sida koodh ah waa la fuliyay, waa mid aad u waxtar leh, iyo qaybaha qaar ka mid ah takhasuska oo dhan loo baahan yahay.

Abuur ASCII

In foomka asalka ah ee koodh waxaa loo sameeyay 1963 ka dibna muddo 25 sano ah laba jeer lala simay.

In version asalka ah ee miiska qof ASCII ka mid ah 128 characters, version dambe u muuqan kordhiyay, halkaas oo 128 characters ugu horeysay waxaa la badbaadiyey iyo codes ku lug leh Calaamooyinka yara siddeedaad baa'bin hore ka maqnaa.

Muddo sanado ah, habaynteeda tani waa kuwa ugu caansan ee dunida. In 2006 meesha keentay qaaday Laatiin ee 1252, iyo dhamaadka 2007 oo hadda haya jagada hoggaamineed si adag koodh caalamiga.

matalaad ASCII Computer

Mid kasta oo ASCII-qof leeyahay code gaar ah oo ka kooban 8 characters, oo ka dhigan eber ama hal. Tirada ugu yar ee wakiilnimo oo kale waa eber (siddeed eber nidaamka binary), taas oo ah isha ugu of element ugu horeysay ee horyaalka.

code binary ugu badnaan in version ASCII ee asalka ah waa waxba kama + toddoba cutub, iyo in version ballaaran - siddeed cutub, ku xiran sida yara siddeedaad.

characters gacanta

Control characters waxaa loo yaqaan calaamado in aadan haysan wakiilnimo a garaafyada iyo waxa loo isticmaalaa ururka qoraalka, maareynta qalab, iwm Waxay astaan u noqon kartaa bilowga ama dhammaadka qoraalka, tabs, guud ahaan signal dhawaaq, hawlaha kala duwan ee TTY (teletype - .. Machine for gudbinta xogta channel korontada) xal of xogta qalabka wax soo saarka, iwm tallaabo la joojiyo.

In miiska qof ASCII jagooyinka 0 ilaa 31, iyo 127 waxaa loo qoondeeyay characters gacanta. Wadarta 33 marks.

The characters haray

The haray 95 jagooyinka loo qoddeeyey marks xarakayn iyo hawlaha xisaabta, lambar jajab tobanle, xarfaha alifbeetada, diiwaanka kala duwan: "A" iyo caasimadda ah "A" waafaqsantahay siman in codes kala duwan ee miiska qof ASCII ah.

lambarada Character in miiska

Haddii qof ayaa ku hawlan horumarinta software, ama si ay u qabtaan qaar ka mid ah hawlaha kale ee duurka ku of technology warbixin ka, waxaa lagama maarmaan ah in la ogaado tirada tiro ka mid ah jilayaasha ASCII.

Sida kor ku xusan, booska uu ka 0-31 iyo 127 qaadan characters gacanta. Number 32 waxa lagu qoray meel, tirada 33-47, iyo 58-64-dan hawlgallada xarakayn iyo xisaabta aasaasiga ah.

xarfaha Latin diyaarin si Horeeyaan iyo kuwa la tiriyey ka 65-aad ilaa 90-aad. warqado kuwa yaryarba ah ayaa sidoo kale loo qabanqaabiyaa si Horeeyaan, ay - laga bilaabo 97 th in 122 th. Tirada haray (91-96 iyo 123-126) loo qoondeeyey ee ku dhxe iyo biraha, uugu oo si toos ah feature, iyo sidoo kale qaar ka mid ah calaamadaha diacritical.

miiska Full calaamadaha ee garaafka ku haboon loo arki karaa in image kor ku xusan. Shaxanka hoose wuxuu muujinayaa tirada Calaamooyin ayaa miiska qof ASCII Ruush.

ASCII Extended

Tan iyo version asalka ah ee koodh la horumariyo, ku salaysan xubin Maraykanka, waxaa aan la siiyaa ma aha oo kaliya noocyada kala duwan ee qoraal iyo alifbeetada qaranka, laakiin xitaa isticmaalka habboon ee diacritics, Si loo isticmaalo oo luqado kala Yurub.

xoogaa 8aad ayaa ku lug for formation of habaynteeda ballaaran. version waxaa ka mid ah calaamadaha ee alifbeetada qaranka Yurub iyo qoraal guun ah, xubno ka graphic, loo isticmaalo loox sawir, tiro ka mid ah calaamadaha xisaabta.

Qaar ka mid ah ASCII characters-waxaa maanta si dhif ah loo isticmaalo. Gaar ahaan, waxay khuseysaa characters in loo isticmaalaa in lagu dhaansado miisaska, sidii sannadihii tan iyo horumarinta habaynteeda ballaaran, wax badan oo siyaabo sahlan ee garaafka miisas lagu soo bandhigay.

National duwanaanshaha habaynteeda

Ka hor dhalashada of ASCII kordhiyay version in uu soo bandhigo characters caalami ah loo isticmaalo koodh version remanufactured, halkaas oo in meel xarfaha laatiinka la dhigay Ruush, Greek, characters Carabi.

Laba codes in miiska loo qoddeeyey bedelaan caadiga ah US-ASCII iyo gool qaranka.

Ka dib markii ASCII noqday ma waxaa ka mid ah 128 iyo 256 characters, faafinta for Xulashada sireed, taas oo version asalka ah ee miiska la badbaadiyey ee 128 codes ugu horeysay la eber yara 8aad. Calaamadaha suugaanta qaranka kaydiyaa bar sare ee miiska (booska 128-255-th).

Si aad u ogaato codes qof si toos ah ASCII user ah looma baahna. sameeysa barnaamijyada software sida caadiga ah waxaa ku filan in la ogaado tirada element ee miiska si ay u xisaabiso code ka, haddii loo baahdo, iyadoo la isticmaalayo nidaamka binary.

af Ruush

Ka dib markii horumarinta ee hore 70-mada ay fartu ee luqadaha Scandinavian, Chinese, Korea, Greek, iwm, Abuuritaanka ay version gaar ah oo ku hawlan arrinta iyo Midowga Soofiyeeti. Soon horumariyo version of habaynteeda 8-bit wuxuu u yeedhay KOI8, badbaadiyaan 128 codes qof ASCII hore iyo qoondeeyay tiro la mid ah jagooyinka ka yar xarfaha alifbeetada qaranka iyo jilayaal dheeraad ah.

Ka hor inta hordhaca ah ee koodh caalamiga KOI8 heysatay in qeybta Ruush ah oo Internetka. Waxaa jiray kala duwanaansho habaynteeda waayo, Ruush, iyo alifbeetada Yukreeniyaan.

dhibaatooyinka ASCII

Tan iyo markii tirada xubno xataa in miiska la dheereeyey kama badna 256, suurtogalnimada uu jaan hal habaynteeda ah dhowr qoraal oo kala duwan oo ka maqan. In 90s waxaa jiray dhibaato ku RuNet "Waan ka xunahay, qashinka" marka text makiinad characters ku ASCII Ruush waxaa si qaldan soo bandhigay.

Dhibaatadu waxay ahayd Meelaan ee codes of fursadaha kala duwan oo midba midka kale ASCII. Xusuustaa in jagooyinka 128-255 waxaa lagu qori karaa calaamado kala duwan, oo marka aad bedesho mid Cyrillic qof ku dhow inay kale, dhammaan xarfaha qoraalka ayaa lagu bedelay kuwo kale oo haysta tirada isku mid in codes kale version.

gobolka hadda

Iyada oo agaa of koodh caalamiga caan ASCII ayaa libirtay.

Sababta tani been in xaqiiqda ah in nooc qof cusub ogol yahay in ay ku jiraan calaamadaha luqadood ku dhowaad dhammaan qoran. Xaaladdan oo kale, 128-characters ASCII ugu horeysay u dhigma qof la mid ah koodh caalamiga.

Sanadkii 2000, wuxuu ahaa ugu caansan ASCII-suntan internetka iyo sida loo isticmaalo by 60% ka mid ah boggaga web "Google" xaddiday. Horeba by 2012 saamiga of pages sida hoos u dhacday 17%, iyo meeshii habaynteeda ugu caansan qaaday koodh caalamiga (UTF-8).

Sayidka, ASCII waa qayb muhiim ah oo ka mid ah taariikhda tiknoolajiyadda macluumaadka, laakiin ay la isticmaalo mustaqbalka u muuqataa unpromising.
