Waehere ASCII (waehere paerewa American mō ngā mōhiohio whakawhitiwhitinga) - te whakawaehere kuputuhi taketake mo te tātai reta Latin

E ai ki te International Telecommunication Union, i roto i te 2016 atu iti iho ranei te whakamahi auau te Internet ki toru me te hawhe piriona iwi. Te nuinga o ratou e kore e ara whakaaro e pā ana ki taua tono tangata ki a ratou mā te PC gadgets pūkoro ranei tetahi karere, me te tuhinga e kua whakaaturia i runga i te aro turuki i o nga mea katoa, i roto i te meka, ko te huinga o 0 me 1. tenei kua karangatia e te māngai whakawaeheretia o te mōhiohio. E whakarato ana i a whakahaere te whakatinanatanga o tona rokiroki, tukatuka, me te tuku. I roto i te 1963, kua whakawhanakehia te waehere ASCII US, e ko te tumu parau o tenei tuhinga.

Whakaaturanga o ngā mōhiohio i roto i te rorohiko

I roto i ngā o tetahi kuputuhi rorohiko hiko ko te kohinga o ngā pūāhua takitahi. I roto ia ratou e kore e te pukapuka anake, tae atu i te whakapaipai, engari ano hoki tohu kārawarawatanga, tau. I tua atu, kei te whakamahia tohu motuhake "=", "&", "(" me ngā mokowā.

He plurality o tohu e hanga ake te kuputuhi, ka karanga te pū, me te tokomaha - mana (denoted rite N). Hei whakatau i te faaiteraa N = 2 ^ b, te wahi b - maha o nga paraire mōhiohio te ngā taimaha tohu ranei.

whakamatauria reira e te mana o 256 pūāhua tātai reta taea ki a koe te tuku i te pūāhua tika katoa.

Mai 256 Ko te 8 tohu e rua, na te taimaha o ia huru ko te 8 paraire.

i huaina Unit o mehua 8 paraire te he 1-paita, na mea tatou e te waehere ā-rua o tetahi pūāhua i roto i te kuputuhi rongoa e te i runga i tō rorohiko, noho kotahi paita o mahara.

Kia pehea te Ko te whakawaehere

Tetahi kuputuhi tomo i roto i te mahara PC i roto i te mau taviri papapātuhi, tau i runga i nei i tuhituhia, pukapuka, tohu tuhi, me te tahi atu tohu. I roto i te mahara e tuku ratou i roto i te waehere ā-rua, arā, i maheretia ia tohu e ki te waehere ira maheni mo te tangata i te 0 ki te 255, e hāngai ana ki te waehere-rua - .. Mai i 00000000 ki 11111111.

whakawaehere pūāhua paita taea te pūtukatuka mahi tukatuka o kuputuhi, tirohia ki ia pūāhua motuhake. I te wa ano, he nui ki te tohu i tetahi mōhiohio pūāhua nga pūāhua 256.

Tapa pūāhua ASCII

tu ana tēnei whakarāpopototanga mo te waehere paerewa English American mō ngā mōhiohio whakawhitiwhitinga.

Ahakoa i te ata o te whakarorohikotanga, ka kitea e he reira taea ki te haere mai ki te momo o huarahi o whakawaehere mōhiohio ake. Heoi, ki te whakawhiti mōhiohio i tetahi rorohiko ki hiahiatia tetahi i ki te whakawhanake i tētahi paerewa kotahi. Na, i roto i te 1963 i reira ko te ASCII-ripanga i roto i te US. whakaritea te reira i tetahi tātai reta rorohiko pūāhua te he tau raupapa i roto i te kanohi pūtakerua. I te tīmatanga, whakamahia te waehere ASCII kei te anake i roto i te United States, a muri ka he paerewa ao mo te PC.

tepu o Ihirangi

E wehea waehere ASCII ki 2 ngā wāhanga. whakaaro paerewa International te ki kia anake te hawhe tuatahi o te tepu. Kei roto te reira i waehere i te tau raupapa o 0 (ā rite 00000000) ki 127 (code 01111111).

Ripanga whakawaehere pūmatua me reta pūriki e whai ake nei tetahi ki tetahi i roto i te ana'iraa piapa, me tau - uara piki ake. Te mau nei teie parau tumu mo te tātai reta Russian.

pūāhua mana

tepu whakawaehere ASCII i hangaia tuatahi mo te fariiraa me te tuku o te mōhiohio i runga i tenei e kore e whakamahia e te pūrere rite te Patowhakaata. I roto i tenei whakaaro, i te huinga pūāhua ngā tākore whakamahia rite whakahau ki te whakahaere i te pūrere. i whakamahia taua whakahau i roto i taua tikanga karere mua rorohiko-rite Morse waehere, a pera atu.

Ko te tino noa "Pato-" tohu ko te NUL (00 "kore"). Kei te whakamahia tonu ia i roto i te nuinga o ngā reo hōtaka, e tohu ana i te tohu o te mutunga o te raina.

Hea whakawaehere ASCII whakamahia

titau te Waehere Paerewa Amerikana kore anake te papapātuhi tomokanga kuputuhi. Kei te whakamahia hoki te reira i roto i te tūtohi. I roto i ngā, i te ASCII Art whakapakoko hōtaka Kaihanga tohu whakawaehere pūāhua ASCII toronga tūāwhiorangi rerekē.

haere mai ēnei hua i roto i te rua ngā momo: ētita whakairoiro e mahi ana i te mahi mā te tahuri i te whakapakoko ki te kuputuhi me tahuri te "Pikitia" i roto i te ASCII-whakairoiro. Hei tauira, mohiotia ko te tauira pirimia Smiley Coding tohu.

Ka taea te whakamahi ASCII ka hanga i te tuhinga HTML. I roto i tenei take, ka taea e koe te tomo i te huinga o ngā pūāhua me te tohu e hāngai ana ki tenei waehere ka puta ina tiro ana te whārangi i runga i te mata.

hiahiatia ASCII kei hoki te hanga pae maha, kia rite ki nga tohu e kore e e no ki te tepu ngā motu, whakakapi i te ASCII-waehere.

ētahi āhuatanga

Hei whakawaehere mōhiohio kuputuhi i roto i te ASCII i whakamahia tuatahi 7 paraire (kotahi noho kau), engari i tenei ra mahi ia rite bit-8 te.

Ko te pukapuka, e kua kei roto i te pou e i runga, me te raro, rerekē i ia atu anake e te moka kotahi. Tenei nui te whakaiti i te matatini o te whakamātautau.

tono ASCII i roto i Microsoft Office

Ki te tika, e taea te whakamahi i tēnei momo o te mōhiohio kuputuhi whakawaehere i roto i ētita kuputuhi e Microsoft, pērā i Pukatuhi, ko Office Word. Heoi, ka pato i roto i tenei take, a koutou e taea e kore te whakamahi i te tahi mau mahi. Hei tauira, e kore e waiho e koe e taea ki te kawe i maia rite te pūāhua ASCII tonu te tikanga anake o ngā mōhiohio, te tau'a ore tona āhua whānui, me te puka.

Waeine

tangohia te whakahaere ISO ISO paerewa 8859. Whakaritea ai e tēnei rōpū te whakawaehere moka-waru hoki ngā rōpū reo rerekē. I roto i ngā, ISO 8859-1 - ko te ASCII whānui, i te mea he tepu mo te United States, a Western Europe. He ISO 8859-5 - ko te tepu whakamahia mo te Cyrillic tātai, tae atu i te reo Russian.

Hoki ngā take hītori ki ISO 8859-5 te whakamahia te reira mo te wa poto.

Hoki te reo Russian i te kau whakawaehere mau whakamahia:

• CP866 (Whārangi Code 866), ranei DOS, Kei te maha i huaina GOST whakawaehere kē. I kaha whakamahia te reira i tae noa ki te waenganui 90-doma o te rau tau whakamutunga. I te kau, tata kore whakamahia.
• Koi-8. i whakawhanakehia Tapa i te 1970-80s, me i te kau, ko te reira te paerewa noa mō ngā karere ī-mēra i RuNet. Kei te whānui whakamahia te reira i roto i te whānau OS Unix, tae atu Linux. "Russian" putanga o koi-8, ka karanga Koi-8R. I tua atu, i reira he putanga mo te ētahi atu reo Cyrillic pērā i Ukrainian.
• Whārangi Waehere 1251 (CP 1251, Windows - 1251). Whakawhanakehia e Microsoft ki te whakarato i te tautoko mo te reo Russian i roto i te taiao Windows.

Ko te painga matua o CP866 paerewa tuatahi ko ki te tiaki pūāhua tupurangi-whakairoiro i roto i te taua tūranga rite i roto i te ASCII whānui. Tenei taea ki a koe rere kuputuhi tonu o te hōtaka, production ke, pērā i te rongonui Norton Commander. I tenei wāhi te whakamahia CP866 mō ngā hōtaka hangaia mō Windows, e mahi i roto i te tirohanga kuputuhi mata-tonu ranei i roto i ngā pouaka kuputuhi, tae atu i roto i te Kaiwhakahaere FAR.

tuhinga Rorohiko tuhituhia i roto i te whakawaehere CP866, hou e tino onge, engari kua whakamahia te reira mo filenames Russian i roto i "Vindous".

"Waehereao"

I te kau, ko te whānui tino ko tenei whakawaehere. Codes "Waehereao" i runga i te mara. Ko te tuatahi (i 0000haora ki U + U + 007F) ngā te huinga o pūāhua ASCII ki waehere. Aru e te pūāhua mara o tuhinga rerekē motu, me te tuhi, me te tohu hangarau. I tua atu, i rongoa wahi o te waehere "Unicode" Kei roto i te take o te hiahia ki te whakauru pūāhua hou i roto i te heke mai.

Na e matau ana koutou e i roto i te ASCII māngai ia huru e rite te huinga o te 8 ngā kore, me te hunga. Ke, kia titiro tenei mōhiohio faufaa, me te uninteresting, engari e kore e hiahia ana koe ki te mohio te mea kei te haere i runga i "i roto i te roro" o tō rorohiko?!
