ASCII code - Mndandanda wa zilembo ndi zizindikiro
El American Standard Code for Information Interchange kapena ASCII, chifukwa cha chidule chake mu Chingerezi, ndilo dzina loperekedwa ku skabisidwe ka zilembo.
Mwa njira iyi, kugawana zambiri kumakhala kosavuta, chifukwa mafayilo omwe timawawona pa kompyuta imodzi amawoneka mofanana ndi ena, ndipo mwanjira iyi, palibe kutaya chidziwitso.
Kodi ASCII ndi chiyani?
ASCII code ndi code yomwe zimachokera ku kufunika kosinthana zambiri popanda kusokoneza kuchokera ku kompyuta imodzi kupita ku ina.
Tiyeni tikumbukire kuti kumayambiriro kwa zaka zamagetsi, makompyuta amatha kulembedwa payekha, popeza mtengo ndi zofuna zimalola, koma pamene makompyuta akukula, ndipo, kuwonjezerapo, kufunikira kwawo kunakhala kovuta kwambiri.
Panafunika dongosolo lomwe linali ndi zipangizo zonse kuti mafayilo omwewo azitha kuwerengedwa mofanana pa kompyuta imodzi ndi pa ina mosasamala kanthu za mtunda.
Mwanjira imeneyi, kusinthana kwa chidziwitso kumakhala kothandiza kwambiri komanso kothandiza.
Khodi ya ASCII imagawidwa m'mitundu ingapo, kutengera ntchito yomwe mukufuna kugwiritsa ntchito komanso zomwe ziyenera kukonzedwa ndi katswiri kuti agwire bwino ntchito.
Ndikofunikira kudziwa momwe chilankhulo chamtundu uwu ndi ndondomeko zolembera zimagwirira ntchito pamakompyuta ngati mukufuna kuzama mozama pamutuwu, popeza ASCII ndi chinthu chofunikira pakugwira ntchito moyenera kwa zida.
Poyamba, m'zaka za m'ma 60, code iyi ya ASCII inakhazikitsidwa pazigawo zisanu ndi ziwiri, kulola kusungidwa kwa zilembo 128, kuphatikizapo:
- ASCII code control zilembo kuphatikiza 31 yoyamba
- Zilembo zosindikizidwa za ASCII kukhala zotsatirazi mpaka 128.
Mwa njira imeneyi, osati kokha kulemba ndi kuona owona pa kompyuta, koma panali kuthekera kwa kutumiza malamulo kwa izo kudzera pa kiyibodi ndi kuti kanthu kena kadzachitidwa chifukwa cha ASCII Code.
Kuti akwaniritse zosowa zovuta kwambiri, patapita zaka zingapo ma code a ASCII adapangidwa, omwe amaphatikizapo tildes (´) , umlauts (ü) ndi zizindikilo zina mudongosolo.
Zizindikiro zomwe timagwiritsa ntchito tsiku ndi tsiku zaperekedwa mu tebulo ili momwe nthawi zambiri zimakhala mbali ya ASCII code, komanso ntchito zomwe zimachitidwa miniti iliyonse.
Gome ili ndi losavuta, koma simuyenera kudziwa mozama kuti ma code omwe amaperekedwa pachochitika chilichonse ndi chiyani kuti athe kukhala. gwiritsani ntchito code ya ASCII moyenera.
Kuti mumvetse izo, n'zosavuta, ndi ASCII code ndi yapadziko lonse lapansi, pafupifupi zipangizo zonse zili nazo ndipo chifukwa cha izi, tikhoza kumvetsa zomwe zimafalitsidwa.
Mwa njira iyi, kugwiritsa ntchito zizindikiro zomwe zili mbali ya ASCII ndizosiyana kwambiri, zomwe zimaperekedwa ndi manambala osiyanasiyana ndipo zimatipatsa mwayi wowona zomwe tikufuna kulankhulana popanda kusintha chidziwitso., kotero kuti fayilo yomwe mumapanga pa chipangizo chimodzi idzawoneka chimodzimodzi mukatsegula pa ina.
Kodi zimatithandiza bwanji kulankhulana? Chabwino, mosasamala kanthu za chinenero chomwe mumalankhula, "a" ndi chimodzimodzi ku Latin America ndi ku Ulaya monga momwe zilili ku ASIA ndi United States.
Ndendende, kufunikira kowona chimodzimodzi chomwe timapanga pa chipangizo chimodzi pa china ndizomwe zimapangitsa kuti ma code osindikizira atheke, chifukwa pamaso pawo, zomwe mudawona pa kompyuta imodzi sizinali zofanana ndi zomwe mungawone pa wina.
Kudutsa kwa chidziwitsochi kuchokera ku kiyi yomwe timasindikiza polemba chilembo mpaka kuwonetsedwa pakompyuta kumayimiridwa ndi chimodzi mwa zizindikiro zosindikizidwa ndi zowonjezera za code ya ASCII kupyolera mu manambala omwe adapatsidwa kale patebulo.
Ndi mitundu yanji ya ASCII code ilipo?
M'malo mwake, pali mitundu itatu ya code ya ASCII yomwe imakhudza magwiridwe antchito onse a chipangizocho, osati kungoyang'anira kokha komanso zizindikiro ndi zizindikilo, pakati pazizindikiro zomwe tili nazo:
Control ASCII - Mndandanda wa zilembo ndi zizindikiro
Ndiwo omwe amatithandiza kuti tizitsatira malamulo popanda kufunikira nthawi zina kugwiritsa ntchito makiyi komanso kuti, kuwonjezera apo, timathandizira kugwirizana pakati pa zipangizo zonse.
Momwemonso, chifukwa cha zizindikiro zowongolera izi titha kulumikiza makiyi ndi zomwe tikuwona pazenera, ndiye, tikamagwiritsa ntchito fungulo la DELETE, code yaperekedwa kwa iyo yomwe imachitidwa munkhani ya milliseconds. kuti agwire ntchitoyo.
Kuti timvetsetse bwino, fungulo lomwe lili ndi logo ya Windows kapena mawu oti "Menyu" likakanikiza, limatsegula poyambira pomwe mapulogalamu onse amawonekera ndipo ngati tisuntha ndi mivi kupita komwe tikufuna ndikupereka "Lowani" key, ntchito idzayenda ndipo zonsezi ndi chifukwa cha zizindikiro zowongolera zomwe tidakambirana.
Mwachidule, zizindikiro zowongolera ndizomwe zimatilola kuchita ntchito pakompyuta popanda kuzichita mwachindunji, mwachitsanzo, ngati tikufuna kutumiza chikalata kuti tisindikize ndi ntchito ya Ctrl + Alt, ndipo zokambirana zosindikiza zimawonekera.
Osati izi zokha, koma amagwiritsidwa ntchito pa malamulo ena ambiri, monga "Esc" chinsinsi chotuluka pa YouTube mawonekedwe azithunzi zonse, mwachitsanzo.
Kapenanso batani la "Delete" lomwe nthawi iliyonse mukasindikiza chotsani zomwe zasankhidwa kapena kufufuta zomwe zili kumanja kwa ndimeyo kapena manambala omwe mukugwiritsa ntchito., mosiyana ndi kiyi yochotsa yomwe imachotsa manambala kumanzere.
Sizingochitika ndi makiyi apadera omwe amachitira zinthu mkati mwa makompyuta, koma ndi zilembo ndi manambala omwe ali mu hardware monga kiyibodi pa kompyuta kapena kusankha kukhudza pawindo kuti code ASCII itheke, ndi zilembo zowonjezera ndi zosindikizidwa.
Zilembo zowonjezera komanso zosindikizidwazi zimaphatikizapo zilembo, manambala, komanso zizindikiro zomwe zimagwiritsidwa ntchito ndi anthu wamba.
Zosindikiza za ASCII - Mndandanda wa zilembo ndi zizindikiro
![Khodi ya ASCII ya “]” – Tsekani m’mabulaketi – bulaketi yakumanja](https://codigos-ascii.com/wp-content/uploads/Codigo-ASCII-de-Cierra-corchetes-Corchete-derecho.png)
Timalankhula ndiye za zilembo zosindikizidwa za code iyi, popeza zomwe titha kuziwona ndi gawo la mafayilo, Ndiwo omwe tingathe kuwawona bwino.
Zizindikiro zosindikizidwazi zimaperekedwa, ndi chizindikiro chilichonse ndi zilembo, ndipo zimagwirizana ndi nambala yomwe ili kukonzedwa mkati ndi kompyuta kumene iwo kukonzedwa.
Pali, mosiyana ndi yapitayi, zizindikiro zosindikizidwa zomwe ndi zomwe tingathe kuziwerenga pa kompyuta, ndiko kuti, zilembo ndi manambala omwe amawonetsedwa m'njira ya chilengedwe chonse, kusintha kokha chinenero ngati kuli kofunikira.
Zilembozi zikuimiridwa ndi nambala yomwe imayimiridwa ndi nambala ya ASCII, ndiko kuti, chilembo chimaimira nambala m'chinenero cha mapulogalamu apakompyuta.
Komabe, manambala awa sizomwe zikuwonetsedwa pazenera, kotero zilembo zazing'ono kapena zazikulu zimagwirizana ndi nambala yosiyana kotero kuti lero mutha kuwerenga nkhaniyi.
Chifukwa cha zomwe tafotokozazi, ndi kudziwa kufunikira kochita chilankhulo chabwino komanso kalembedwe kabwino Kaya chinenero chinasankhidwa kapena cholankhulidwa chotani, panafunika kulemba zilembo ndi manambala m’njira yachilengedwe chonse kuti chidziŵitsocho chisasokonezedwe.
Zowonjezera za ASCII - Mndandanda wa zilembo ndi zizindikiro
Amapangidwa kuti azipereka ntchito "zapamwamba" pama code onsewa.
Khodi ya ASCII yawonjezera zilembo zomwe zimayankha pachofunikira chovuta kwambiri.
Zizindikiro zowonjezerazi zimasanjidwanso patebulo ndipo zimaimiridwa ngati ziwiri zam'mbuyomo pogwiritsa ntchito manambala.
Kuchokera pakuyika apostrophe, umlaut, tilde, zizindikiro zopumira, zizindikiro, pakati pa zizindikiro ndi zizindikiro zina, ndizotheka chifukwa cha zilembo zowonjezereka zomwe zili mbali ya code ya ASCII.
Ndilo gawo lazizindikiro zofunikira komanso zofunikira ndi zizindikiro za equation yasayansi monga chizindikiro chowonjezera "+" kapena chizindikiro cha magawo "-".
Ndi chiyani?
Kuti ikhale yosavuta komanso yamadzimadzi, nambala ya ASCII imagwiritsidwa ntchito kuyimira nambala iliyonse yomwe imagwiritsidwa ntchito polemba, kuchita kanthu kapena kupereka munthu wapadera.
Ndiko kuti, code ya ASCII ndi kumasulira kwa manambala kapena kusintha komwe wogwiritsa ntchito amagwiritsa ntchito kuti athe kuyendetsa dongosolo pa nthawi yake, popeza makompyutawa amangogwiritsa ntchito zizindikiro za binary monga chinenero cha ntchito zomwe zimayimira ntchito zawo zomveka.
Mwa njira iyi, khalidwe lililonse, chilembo, chizindikiro, malo, chizindikiro komanso ngakhale malo opanda kanthu ali ndi chiwerengero cha chiwerengero chomwe chimagwirizana ndi ASCII code ndipo izi zimayimiridwa mosavuta patebulo.
Kuyambira pomwe idakhazikitsidwa mu 1967. momwe idakonzedwanso pang'onopang'ono mpaka kukwaniritsa zomaliza zake mu 1986, ma code ASCII ali ndi ntchito yabwino padziko lonse lapansi pazida zilizonse zomwe zatchulidwa.
M'kupita kwanthawi, mitundu yosiyanasiyana ya ma codeyi idapangidwa, monga ma code owonjezera.
Kuti mukwaniritse kulumikizana bwino kwamakina pogwiritsa ntchito ma code osindikizika, otambasulidwa komanso owongolera, kunali kofunikira kulembera makina aliwonse omwe alipo payekhapayekha, popeza zida zomwe zidasinthidwa zidasinthidwa kale.
Takambirana kuti zilembo za ASCII zimagwiritsidwa ntchito nthawi zambiri zolumikizidwa ndi mizere yamalemba, komabe zimagwirizananso kwambiri ndi ma equation asayansi chifukwa zizindikiro zambiri ndi zizindikiro zomwe zilipo ndi gawo la zizindikiro zowonjezera.
Monga momwe kusindikiza kumapangidwira mosavuta ndi mawonekedwe owongolera omwe amaperekedwa kwa Ctrl + P, omwe amatsegula zenera kuti asankhe zambiri ndi katundu kuti asindikize pepala, ASCII code imapangitsa ntchito zina zambiri zotheka.
Pakati pawo, ntchito za zilembo zosindikizidwa ndi zowonjezera zimawonekera, popeza izi ndi zomwe Iwo amatilola ife zambiri madzimadzi chinenero ndi kulankhulana popeza ndi amene amatheketsa kugwiritsa ntchito zilembo, zizindikiro ndi zizindikiro.
Kodi ASCII code imagwiritsidwa ntchito bwanji?
Programming ndi chilankhulo cha pakompyuta chomwe ndi chovuta kwambiri.
Mudzaphunzira kugwiritsa ntchito kachidindo ka ASCII kutengera makina omwe muli nawo, komabe, mukuchita kale osazindikira.
Chifukwa chake, malamulo omwe timapanga kudzera pakompyuta yanu ndi malamulo a ASCII omwe adakonzedwa kale ndi akatswiri kuti mutha kulumikizana ndi madzimadzi komanso kulumikizana bwino ndipo mutha kuwapeza onse atayikidwa patebulo.
Pali njira zopezera ma code a ASCII ndipo zimachitika polemba mawu ena pamanja, kudzera pa kiyibodi kapena kudzera mudongosolo. Mwachitsanzo:
Pazenera
Ndizotheka kuti mutha kuyika malamulo omwe sali pa kiyibodi pogwiritsa ntchito mapu amtundu, sikoyenera kuti mudziwe zomwe zili patebulo, chifukwa chake dinani batani loyambira.
Zenera likangowoneka, mulembapo "charmap" m'malo osakira ndipo mudzadina zomwe mukufuna, kenako mapu a zilembo zosindikizidwa ndi zowonjezera zomwe simunawonepo zidzawonekera.
Zimatengera ntchito yomwe mukuchita, chifukwa ngati mukufuna kuchita zina zowonjezera muyenera kuyang'ana kachidindo kantchito yomwe muti mugwiritse ntchito patebulo.
Koma izi zidalira pa machitidwe aliwonse omwe tikukamba.
Pa Linux
Njirayi imakhala yosiyana pang'ono chifukwa zizindikiro zowongolera zimasintha ndipo muyenera kutero mukudziwa hex kodi zomwe mukufuna, chifukwa nthawi zambiri machitidwe ena awiri am'mbuyomu amagwiritsa ntchito ma decimals.
Kuti zenera litseguke kuti mulembe imodzi mwama code owongolera, muyenera kukanikiza makiyi a Ctrl + Shift + U kuti mukatsegula kusaka ndikulowetsa nambala ya hexadecimal yomwe ili patebulo.
Mumadziwa zomwe code yomwe mungagwiritse ntchito ikhala patebulo pomwe code iliyonse yomwe mukufuna imalembedwa.
Sikoyenera kuloweza khodi iliyonse, ndikuchita mudzaphunzira zofunika kwambiri komanso ndiye simukusowa nkomwe kuwona ma code.
Pa Mac
Ngati muli pa chipangizo chokhala ndi makina ogwiritsira ntchito a iOS ngati omwe amagwiritsidwa ntchito ndi Mac, tigwiritsa ntchito njira zazifupi za kiyibodi.
Pali zingapo ndipo zimasiyana malinga ndi zomwe mukufuna, mwachitsanzo:
- Kuti mutuluke pulogalamu iliyonse pa Mac mufunika lamulo la Tulukani, mwina ndi njira yachidule kapena ndi menyu mu pulogalamuyo chifukwa ndi mtanda wofiyira (x) sichimatuluka kwathunthu.
- Komabe, mukasindikiza CTRL + CMD + space, kiyibodi imawonekera.
- Mukasindikiza Shift mudzawona zilembo zonse mu zilembo zazikulu
- Mukasindikiza Alt mudzatha kupeza zilembo zonse zapadera, ngati sizikuwoneka dinani chizindikiro chakumanja chakumanja ndikusankha onetsani kiyibodi.
Zofunikira pamakompyuta apano
Zilembo zowonjezera za ASCII ndizofunikira pakugwira bwino ntchito kwa kompyuta, monganso zosindikizira ndi zilembo zowongolera.
Mwanjira imeneyi, adagwirizana kuti onse opanga mapulogalamu azigwiritsa ntchito chilankhulo cha pakompyuta chifukwa Kufunika kwa makompyuta ndi zipangizo zonse kukhala ndi chinenero chimodzi kunabadwa.
Ndizosatheka kugwiritsa ntchito kompyuta popanda kuchita mbali ya kachidindo ya ASCII, popeza makompyuta ambiri amagwirizana nawo, izi zimapangitsa kutumiza zidziwitso kumachitika moyenera komanso mwadongosolo.
Ngati kachidindo kameneka sikanapangidwe kuyambira m’ma 60, zikanakhala zovuta kwambiri kuti muzitiwerengera, kapena tikhoza kulemba nkhaniyi, komanso sizikanakhala ndi kalembedwe kabwino komanso zizindikiro zopumira ngati sichoncho kupanga ma code owonjezera.
Popeza zikomo ndendende ndi izi, zimatilola kuti tiziphatikiza zilembo ndi zizindikilo zoperekedwa ndi code ya ASCII.
Mwinamwake mukudziwa kale kuti chinenero cha binary ndizomwe zimapangitsa kuti kompyuta igwire ntchito ndikumasuliranso malangizo omwe timapereka ku chipangizocho, zilizonse zomwe zingakhale.
Momwemonso, code ya ASCII imatithandiza kuti tizilankhulana ndi kompyuta kudzera m'chinenero chathu, zirizonse zomwe zingakhale. popanda kufunikira kodziwa momwe zimagwirira ntchito mkati.
Inde, nthawi iliyonse mukalemba chilembo kapena kugunda batani la "Delete", pamakhala ma code omwe amakonzedwa mu milliseconds kuti akwaniritse malamulowo.
Malamulo awa nthawi zambiri amakhala chifukwa cha kukhazikitsidwa kwa madongosolo amtundu uliwonse kapena zolemba pamakompyuta, ndipo nthawi zambiri, wosuta amanyalanyaza ndondomeko yonse kumbuyo kuti dongosolo lanu lichitidwe, popeza dongosololi limachita zokha.
Ngati mukufuna zambiri za momwe amagwiritsidwira ntchito kapena ma code a ASCII, pali tebulo lomwe liri ndi udindo wofotokozera ndondomeko iliyonse momwe ikugwiritsidwira ntchito, nambala ya decimal kapena hexadecimal.
Kusiyanitsa kwamakhodi kudzaperekedwa ndi makina omwe mumagwiritsa ntchito, kaya Windows, Mac kapena Linux. Mutha kuziwona patebulo pamwambapa.
Ngakhale zakhala zikusinthidwa kuyambira 60s, khodi ya ASCII sinadziwike konse.
Anthu ambiri akupitiliza kuzigwiritsa ntchito chifukwa ndi quintessential code yogwiritsa ntchito yomwe imayimira decryption ya machitidwe onse apakompyuta, kotero kuti titha kugawana zambiri bwino komanso moyenera komanso, zimakonzedwa padziko lonse lapansi patebulo.
Pomaliza, chinenero cha pakompyuta chimene okonza mapulogalamu ambirimbiri anachipanga n’kuchipanga kukhala changwiro lerolino chimatheketsa kulemba ndi kuzindikira zambiri bwino lomwe. zilibe kanthu kuti muli pa kompyuta yanji.
The American Standard Code for Information Interchange, kapena ASCII malinga ndi katchulidwe kake mu Chingerezi, ndi mndandanda wa zilembo ndi zizindikiro patebulo zomwe zilipo pazida zonse kuti chidziwitsocho chimveke bwino komanso zisasokonezedwe pazida zosiyanasiyana.
Zizindikirozi zomwe mudzaziwona patebulo lero ndi gawo la zonse zomwe tikudziwa lero pa intaneti ndipo chifukwa cha khama la opanga mapulogalamu tingathe kulankhulana.
