ASCII code - Cov lus ntawm cov cim thiab cov cim

El American Standard Code for Information Interchange los yog ASCII, ua tsaug rau nws acronym hauv lus Askiv, yog lub npe muab rau lub scim encoding system.

Nyob rau hauv txoj kev no, sib qhia cov ntaub ntawv yog yooj yim dua, vim hais tias cov ntaub ntawv uas peb pom nyob rau hauv ib lub computer yog pom nyob rau hauv tib txoj kev rau lwm tus, thiab nyob rau hauv txoj kev no, tsis muaj cov ntaub ntawv poob.

ASCII code yog dab tsi?

ASCII code yog code uas tshwm sim los ntawm qhov yuav tsum tau sib pauv ntaub ntawv tsis muaj distortion ntawm ib lub computer mus rau lwm tus.

Cia peb nco ntsoov tias thaum pib ntawm lub hnub nyoog hluav taws xob, khoos phis tawj tuaj yeem ua tus lej ntawm tus kheej, txij li tus nqi thiab kev thov tau tso cai, tab sis raws li lub khoos phis tawj loj hlob tuaj, thiab, ntxiv rau, qhov kev thov rau lawv tau dhau los ua nyuaj.

Yuav tsum muaj lub kaw lus uas muaj tag nrho cov khoom siv kom tib cov ntaub ntawv tuaj yeem nyeem sib npaug ntawm ib lub khoos phis tawj thiab ntawm lwm qhov tsis hais nyob deb.

Nyob rau hauv txoj kev no, kev sib pauv ntawm cov ntaub ntawv muaj txiaj ntsig zoo dua thiab muaj txiaj ntsig. 

ASCII code tau muab faib ua ntau hom, nyob ntawm qhov ua haujlwm uas koj xav siv thiab qhov yuav tsum tau ua los ntawm tus kws tshaj lij kom ua haujlwm raug. 

Nws yog ib qho tseem ceeb kom paub tias hom lus no thiab txheej txheem coding ua haujlwm li cas hauv kev suav yog tias koj xav delve me ntsis tob rau hauv cov ncauj lus no, txij li ASCII yog ib yam dab tsi yooj yim rau kev ua haujlwm zoo ntawm cov khoom siv. 

Thaum pib, xyoo 60, ASCII code no tau tsim los ntawm xya-ntsis, tso cai rau kev tso npe ntawm 128 tus cim, suav nrog:

  • ASCII code tswj cov cim suav nrog thawj 31
  • ASCII code printable cim yog cov nram qab no mus txog 128.

Ua li no, tsis tsuas yog ua tau sau thiab saib cov ntaub ntawv hauv computer, tab sis muaj qhov muaj peev xwm xa cov lus txib rau nws los ntawm cov keyboard thiab tias qhov kev txiav txim tshwj xeeb yuav raug ua ua tsaug rau ASCII Code.

Txhawm rau kom txaus siab me ntsis kev xav tau, xyoo tom qab txuas ntxiv ASCII cov lej tau tsim, uas suav nrog tildes (´), umlauts (ü) thiab lwm cov cim hauv lub cev.

Cov cim uas peb siv niaj hnub raug muab tso rau hauv cov lus no los ntawm lawv feem ntau yog ib feem ntawm ASCII code, nrog rau cov haujlwm uas tau ua txhua feeb. 

Cov lus no yog qhov yooj yim heev, tab sis koj tsis tas yuav paub qhov tob ntawm cov lis dej num uas tau muab rau txhua qhov kev txiav txim kom lawv tuaj yeem ua tau. ua kom raug ASCII code. 

Yuav kom nkag siab nws, nws yog heev yooj yim, lub ASCII code yog universal, yuav luag txhua yam khoom siv muaj lawv thiab ua tsaug rau qhov no, peb tuaj yeem nkag siab cov ntaub ntawv uas tau xa mus.

Nyob rau hauv txoj kev no, kev siv cov lej uas yog ib feem ntawm ASCII muaj ntau yam sib txawv, muab cov lej sib txawv thiab lawv muab rau peb pom qhov peb xav sib txuas lus yam tsis hloov cov ntaub ntawv., yog li cov ntaub ntawv koj tsim ntawm ib lub cuab yeej yuav zoo tib yam thaum koj qhib nws ntawm lwm qhov. 

Lawv pab peb nrog kev sib txuas lus li cas? Zoo, tsis hais hom lus koj hais, "a" yog tib yam hauv Latin America thiab Europe raws li nws nyob hauv ASIA thiab Tebchaws Meskas. 

Precisely, qhov yuav tsum tau pom raws nraim tib yam uas peb tsim ntawm ib lub cuab yeej ntawm lwm tus yog dab tsi ua rau cov lej luam tawm tau, vim tias ua ntej lawv, qhov koj pom ntawm ib lub computer tsis zoo ib yam li qhov koj yuav pom ntawm lwm tus. 

Qhov dhau ntawm cov ntaub ntawv no los ntawm tus yuam sij uas peb nias thaum ntaus ntawv kom txog rau thaum nws tshwm sim hauv lub khoos phis tawj yog sawv cev los ntawm ib qho ntawm cov lej luam tawm thiab txuas ntxiv ntawm ASCII code los ntawm cov lej uas tau muab yav dhau los hauv lub rooj.

Dab tsi ntawm ASCII code muaj?

Nyob rau hauv txoj cai, muaj peb hom ASCII code uas npog cov kev khiav hauj lwm ntawm lub cuab yeej, tsis tsuas yog nws cov kev tswj, tab sis kuj cov cim thiab cov cim, ntawm cov codes peb muaj:

Lawv yog npaj los muab cov feem ntau "advanced" functions ntawm tag nrho cov codes.

ASCII code tau txuas ntxiv cov cim uas teb rau qhov xav tau ntau dua.

Cov lej txuas ntxiv no kuj tau teem rau hauv ib lub rooj thiab tau sawv cev zoo li ob qho dhau los los ntawm kev siv lej lej.

Los ntawm muab ib qho apostrophe, umlaut, tilde, cov cim cim, cov cim exclamation, ntawm lwm cov cim thiab cov cim, lawv muaj peev xwm ua tsaug rau cov cim txuas ntxiv uas yog ib feem ntawm ASCII code.

Nws tseem yog ib feem ntawm cov cim tseem ceeb thiab cov cim rau kev sib npaug ntawm kev tshawb fawb xws li kos npe ntxiv "+" lossis faib kos npe "-".

Dab tsi yog nws rau?

Txhawm rau ua kom yooj yim thiab ua kua dej, ASCII code yog siv los ua tus lej sawv cev rau txhua tus cim uas siv los sau, ua ib qho kev nqis tes ua los yog muab tus cwj pwm tshwj xeeb.

Ntawd yog, ASCII code yog tus lej txhais lus lossis hloov pauv uas tus neeg siv siv los tswj hwm lub kaw lus ntawm nws qhov yooj yim, txij li cov khoos phis tawj no tsuas yog tuav binary codes ua hom lus ntawm kev ua haujlwm uas sawv cev rau lawv cov kev ua haujlwm zoo.

Nyob rau hauv txoj kev no, txhua tus cim, tsab ntawv, kos npe, qhov chaw, cim thiab txawm tias txhua qhov chaw khoob muaj cov lej ua haujlwm uas sib haum rau ASCII code thiab cov no tau yooj yim sawv cev hauv ib lub rooj.

Txij li thaum nws tsim nyob rau hauv 1967, nyob rau hauv uas nws tau ua tiav me ntsis los ntawm me ntsis txog thaum ua tiav nws qhov kev hloov tshiab kawg hauv xyoo 1986, ASCII cov lej muaj kev ua haujlwm zoo thoob ntiaj teb hauv txhua yam khoom siv uas tau hais.

Raws li nws tau ua tiav, ntau yam ntawm cov lej no tau tsim, xws li cov lej txuas ntxiv.

Txhawm rau ua tiav qhov kev sib txuas lus zoo tshaj plaws los ntawm kev luam tawm, txuas ntxiv thiab tswj cov lis dej num, nws yog ib qho tsim nyog yuav tsum tau code txhua thiab txhua lub tshuab uas twb muaj lawm ib tus zuj zus, txij li cov khoom siv kho tshiab twb tau txiav txim siab lawm.

Peb tau tham txog tias ASCII cov lej feem ntau siv txuas nrog cov kab ntawv, tab sis txawm li cas los xij lawv kuj muaj feem cuam tshuam nrog scientific equations vim hais tias ntau ntawm cov paib thiab cov cim tam sim no muaj ib feem ntawm cov lej txuas ntxiv.

Ib yam li kev luam ntawv tau yooj yim dua los ntawm kev tswj hwm tus cwj pwm uas tau muab rau Ctrl + P, uas cia li qhib lub qhov rais rau xaiv cov ntsiab lus thiab cov khoom los luam ib daim ntawv, ASCII code ua rau muaj ntau yam haujlwm ntxiv.

Ntawm lawv, cov haujlwm ntawm cov ntawv luam tawm thiab cov cim txuas ntxiv sawv tawm, vim cov no yog cov uas Lawv tso cai rau peb muaj ntau hom lus thiab kev sib txuas lus vim lawv yog cov uas ua rau muaj peev xwm siv cov ntawv, cov cim thiab cov cim.

Yuav siv ASCII code li cas?

Programming yog ib hom lus hauv computer uas nyuaj heev. 

Koj yuav kawm siv ASCII code nyob ntawm qhov kev ua haujlwm uas koj muaj, txawm li cas los xij, koj twb ua nws yam tsis tau paub txog nws.

Yog li, cov lus txib uas peb ua los ntawm koj lub khoos phis tawj yog ASCII cov lus txib uas tau ua dhau los los ntawm cov kws tshaj lij kom koj tuaj yeem muaj kev sib txuas lus ntau dua thiab muaj txiaj ntsig thiab koj tuaj yeem pom lawv txhua tus xaj hauv lub rooj.

Muaj ntau txoj hauv kev los siv cov ASCII cov lej no thiab lawv tau ua los ntawm kev nkag qee cov lus manually, los ntawm cov keyboard lossis los ntawm lub kaw lus. Piv txwv li:

Ntawm qhov rais

Nws yog qhov ua tau tias koj tuaj yeem ntxig cov lus txib uas tsis nyob ntawm cov keyboard tsuas yog siv daim ntawv qhia ua cim, nws tsis tsim nyog koj paub cov ntsiab lus ntawm lub rooj, rau qhov no koj nyem lub pob pib.

Thaum lub qhov rais tshwm, koj yuav tsum sau muaj "charmap" nyob rau hauv kev tshawb fawb teb thiab koj yuav tau nyem rau ntawm qhov kev tshwm sim thiab ces ib daim ntawv qhia ntawm printable thiab extensible cim uas koj tsis tau pom ua ntej yuav tshwm sim.

Nws nyob ntawm tag nrho cov haujlwm uas koj yuav tau ua, txij li yog tias koj xav ua kom tiav ib qho haujlwm ntxiv koj yuav tsum xyuas cov cai ntawm txoj haujlwm uas koj yuav siv hauv lub rooj.

Tab sis qhov no yuav nyob ntawm txhua qhov kev khiav hauj lwm peb tab tom tham txog.

Nyob rau Linux

Cov txheej txheem feem ntau txawv me ntsis vim tias cov cai tswj kev hloov pauv thiab koj yuav tsum tau paub hex code uas koj xav tau, vim hais tias feem ntau lwm ob lub tshuab ua haujlwm dhau los siv cov lej. 

Txhawm rau kom lub qhov rais qhib los sau ib qho ntawm cov cai tswj hwm, koj yuav tsum nias Ctrl + Ua haujlwm + U yuam sij kom tom qab qhib qhov tshawb nrhiav koj nkag mus rau hexadecimal code uas nyob hauv lub rooj.

Koj paub tias tus lej siv dab tsi yuav dhau los ntawm lub rooj uas txhua tus lej koj xav tau sau.

Nws tsis yog qhov tsim nyog yuav tsum tau cim txhua tus lej, nrog rau kev xyaum koj yuav kawm qhov yooj yim tshaj plaws thiab ces koj tsis tas yuav saib cov lis dej num.

Nyob Mac

Yog hais tias koj nyob rau hauv ib tug ntaus ntawv nrog ib tug iOS operating system zoo li ib tug siv los ntawm Mac, peb yuav siv cov keyboard shortcuts.

Muaj ntau ntau thiab nws yuav txawv nyob ntawm seb koj xav tau dab tsi, piv txwv li:

  • Txhawm rau kom tawm tag nrho cov kev pab cuam ntawm Mac koj yuav xav tau Exit hais kom ua, nrog rau qhov shortcut lossis nrog cov ntawv qhia zaub mov hauv daim ntawv thov vim tias nrog tus ntoo khaub lig liab (x) nws tsis tawm hauv daim ntawv thov kiag li.
  • Txawm li cas los xij, yog tias koj nias CTRL + CMD + qhov chaw, cov keyboard yuav tshwm sim.
  • Yog tias koj nias Shift koj yuav pom tag nrho cov tsiaj ntawv loj
  • Yog tias koj nias Alt koj tuaj yeem nkag mus rau tag nrho cov cim tshwj xeeb, yog tias nws tsis tshwm sim nyem rau ntawm lub cim nyob rau sab xis thiab xaiv cov keyboard saib pom.

Kev tsim nyog hauv kev suav tam sim no

Extended ASCII code cim yog qhov yooj yim rau kev ua haujlwm zoo ntawm lub khoos phis tawj, xws li luam tawm thiab tswj cov cim. 

Ua li no, nws tau pom zoo tias txhua tus programmers yuav siv tib yam lus hauv computer vim Qhov xav tau rau txhua lub khoos phis tawj thiab khoom siv kom muaj cov lus tib yam tau yug los.

Nws tsis yooj yim sua kom siv lub khoos phis tawj yam tsis tau ua ib feem ntawm ASCII code, vim tias feem ntau cov khoos phis tawj tau sib xws nrog nws, qhov no ua rau lub khoos phis tawj ua haujlwm tau zoo. Kev hloov cov ntaub ntawv yog ua tiav thiab tswj tau zoo.

Yog tias cov cai no tsis tau tsim txij li xyoo 60, nws yuav nyuaj heev rau koj los nyeem peb, lossis peb tuaj yeem sau tsab xov xwm no, thiab nws yuav tsis muaj kev sau ntawv zoo thiab cim cim yog tias tsis yog rau kev txhim kho cov lej txuas ntxiv.

Txij li ua tsaug rau qhov no, nws tso cai rau peb nkag mus rau kev sib txuas ntawm cov cim thiab cov cim muab los ntawm ASCII code.

Tej zaum koj twb paub lawm tias lus binary nws yog qhov ua rau nws ua tau rau lub khoos phis tawj ua haujlwm thiab tseem txhais cov lus qhia uas peb muab rau lub cuab yeej, txawm tias nws yuav ua li cas.

Ib yam li ntawd, ASCII code tso cai rau peb sib txuas lus nrog lub computer los ntawm peb hom lus, txawm li cas los xij. tsis muaj qhov yuav tsum tau paub yuav ua li cas nws ua haujlwm sab hauv.

Yog lawm, txhua zaus koj ntaus ntawv lossis ntaus tus yuam sij "Delete", muaj cov lej ua tiav hauv milliseconds kom ua tiav cov lus txib.

Cov lus txib no feem ntau yog tshwm sim los ntawm kev qhia txog kev txiav txim ntawm txhua yam lossis cov ntawv nyeem rau cov khoos phis tawj, thiab feem ntau, tus neeg siv ignores tag nrho cov txheej txheem qab rau koj qhov kev txiav txim kom raug tua, txij li qhov system ua nws tau.

Yog tias koj xav tau cov ntaub ntawv ntxiv txog nws siv li cas lossis cov lej ASCII yog dab tsi, muaj ib lub rooj uas yog lub luag haujlwm rau kev qhia txhua tus lej raws li nws siv, yog decimal lossis hexadecimal codes.

Qhov kev sib txawv ntawm cov lej no yuav muab los ntawm kev ua haujlwm uas koj siv, tsis yog Windows, Mac lossis Linux. Koj tuaj yeem pom nws hauv cov lus saum toj no.

Txawm tias tau hloov kho tas li txij li xyoo 60s, ASCII code tsis tau mus tag nrho unnoticed.

Ntau tus neeg tseem siv nws vim nws yog quintessential code siv uas sawv cev rau decryption ntawm tag nrho cov computer systems, yog li ntawd peb tuaj yeem muab cov ntaub ntawv qhia tau zoo thiab muaj txiaj ntsig thiab tseem, lawv tau npaj thoob ntiaj teb hauv ib lub rooj.

Hauv kev xaus, lub khoos phis tawj hom lus uas ntau txhiab tus programmers tsim thiab ua tiav ua rau hnub no tuaj yeem sau thiab pom cov ntaub ntawv kom meej. tsis muaj teeb meem dab tsi koj nyob rau hauv computer.

American Standard Code for Information Interchange, los yog ASCII raws li nws lub ntsiab lus nyob rau hauv lus Askiv, yog ib tug txheej ntawm cov cim thiab cov cim nyob rau hauv ib lub rooj uas muaj nyob rau hauv tag nrho cov pab kiag li lawm kom cov ntaub ntawv meej thiab tsis raug distorted ntawm cov khoom siv sib txawv. 

Cov lej no uas koj yuav pom hauv lub rooj hnub no yog ib feem ntawm txhua yam peb paub niaj hnub no hauv Is Taws Nem thiab ua tsaug rau qhov kev siv zog no los ntawm programmers peb tuaj yeem sib txuas lus.
