Waehere pūtakerua. Types me te roa o te waehere pūtakerua. waehere ā-rua Whakamuri

waehere ā-ko te ahua o te tuhi pāpāho i roto i te puka o te hunga me ngā kore. he taua pūnaha mō te tātai i te turanga tū 2. Ki te rā, te waehere ā-rua (ripanga aroaro paku raro kei te tahi mau hi'oraa o te tuhi i te tau) e whakamahia ana i roto i nga whakaaro mamati katoa. Ko e tika ana ki te tika tiketike, me te tapatahi o tenei puka urunga Ko tōna rongonui. Ko te tauhanga ā-rua tino māmā, aua, a he mea ohie ki te whakatinana i roto i te taputapu. Digital hiko wāhanga (ranei rite e huaina ratou - arorau) he tino pono rite mahi ratou i roto i āhua e rua anake: he kōwae arorau (arā, te nāianei), me te arorau kore (e kore nāianei). Ko te kupu, whakarite pai ratou ki wāhanga tairitenga, e hāngai ana ki transients.

Kia pehea te ko te ahua ā-rua o tuhituhi?

Kia kite tatou e founga i hanga te kī taua te. Kotahi mati kia ki roto waehere ā-rua āhua e rua anake: te kore me te kotahi (0 me 1). A, no te whakamahi i rua paraire riro taea ki te tuhi wha uara: 00, 01, 10, kei roto 11. Ko te urunga e toru-mati waru āhua: 000, 001 ... 110, 111. Ko te hua ko e te roa o te waehere ā-rua ko ti'aturi i runga i te maha o para. Ka taea te tuhituhi i tēnei faaiteraa te whakamahi i te tātai e whai ake nei: N = 2m, te wahi: m - ko te maha o nga paraire, me N - te maha o ngā.

Ngā momo o waehere ā-rua

Ko te microprocessors Ko nga kī whakamahia ki te tuhi i te momo o te mōhiohio ki te tukatuka. tino taea Bit waehere pūtakerua nui te kaha o te pūtukatuka me tona mahara ā-. I roto i ngā take pēnei, ko te maha o te whanganga roa ngā pūtau mahara maha, me te tukatuka ki te torutoru noa whakahau. I roto i tenei take, nga rāngai mahara katoa e kua tohaina i raro i te maha-paita waehere-rua, kei te whakaaro rite te tau kotahi. Tei runga i te hiahia o tenei e kōrero, nga momo e whai ake nei o taviri ranei:

• i hainatia;
• waehere tselyeznakovye tika;
• whakamuri te rohe;
• tohu atu;
• waehere hina;
• waehere-Express hina.;
• waehere hautanga.

Kia whai whakaaro ano tatou i roto i atu taipitopito i ia o ratou.

waehere ā-rua i hainatia

Kia kite a he aha te tikanga taua puka record. Ko te waehere tōpū waitohu ia bit (ā-rua) mati tohu te tohu e rua. Ko te kupu te tau iti rawa e taea te tuhituhi i roto i tenei puka, ko te kore a taea te māngai te mōrahi e te tātai e whai ake nei: M = 2 ⁿ -1. E tino tāutu ēnei tau e rua te whānuitanga matua, e taea te whakahuatia i roto i te waehere ā-rua. Kia titiro a ki te taea o te puka tomokanga mea. A, no te whakamahi i tenei momo ngā kī waitohu o waru paraire, te whānui o ngā tau ka taea ngā i 0 ki te 255. waehere hautekaumāono ka whai i te whānui mai i te 0 ki te 65535. Ko te pūtukatuka moka-waru hoki pupuri me te tuhi o enei tau mā te whakamahi i rāngai mahara e rua e kua kei roto i kaiwhiwhi pātata . Mahi ki taua matua whakarato whakahau motuhake.

Direct waehere pūāhua katoa

I roto i tenei puka o taviri ā-rua whakamahia MSB te ki te tuhi i te paraharaha tau. Kore hāngai ki me, me wae - tango. Ka rite ki te hua o tenei awhe rere neke tau ā i roto i te aronga kino. Huri i te reira i roto i kia kia tuhituhia bit-waru tau tōpū hainatia tau matua rua i roto i te whānui i -127 ki +127. Hautekaumāono - i roto i te whānui i -32767 ki +32767. Ko te microprocessor moka-waru mo te pupuri taua waehere whakamahi rua rāngai pātata.

He ngoikoretanga o tenei ahua o te tuhi, ko te e me te tukatuka i te paraire matua fakataipe, me te tau motuhake. Hātepe hōtaka mahi ki enei waehere ki te tiki rawa uaua. Hei huri i te kōwhiringa, me te haina paraire e tika ana ki te whakatinana i ngā tikanga e huna kanohi i te huru, e whai wāhi ana ki te hua koi i roto i te rahi pūmanawa me te hekenga i roto i tona mahi. Kua roto i te tikanga ki te whakakore i tenei ngoikoretanga kua whakaurua he momo hou o te matua - whakataka waehere ā-rua.

Waitohu te kī hoki

Ko rerekē i te waehere tika tenei puka o te tuhituhi anake i roto i taua he maha tōraro e whiwhi ai i te tau fulihi nga paraire katoa o te kī. I roto i tenei paraire mamati me tohu e ōrite. Nā ki tenei, te mahi hātepe ki tenei momo o te waehere e tino māmā. Heoi, titau te kī whakamuri he hātepe motuhake mō te mohio ki tohu mati tuatahi, te tātai i te uara pū o te tau. He waihanga anō i te tohu o te uara hua. Ano, i roto i te whakamuri me waehere whakamua tau mō te tuhi e rua taviri e whakamahia kore. Ahakoa te meka e kore e tenei uara i te tohu pai kino ranei.

Hainatia tau-rua waehere atu

Kāore tēnei momo o te record whakarārangitia tōnounou o taviri o mua. Taua waehere tukua aofangatuku tika o e rua ngā tau pai, me te kino. Ko te kupu e kore e te reira puritia tātaritanga tohu moka. ka tenei katoa whakawhetai taea ki te meka e te tau atu ko te mowhiti tohu māori, me te kore te rōpū tāwhaiwhai, pērā i te mau taviri whakamua, me te whakamuri. Ano, ko te take nui ko e te tātai o te tāpiri-ake ki te whakaputa waehere ā-rua, ko te tino ngāwari. He mea nui ki te whakataka kotahi tāpiri matua. A, no te whakamahi i tenei momo o te waehere pūāhua tënei o waru paraire, te whānui o ngā tau ka taea ngā i -128 ki +127. ka whai kī hautekaumāono te whānuitanga o -32768 ki +32767. whakamahi hoki nga pūtukatuka moka-waru mo te pupuri i taua tau e rua rāngai pātata.

waehere pūtakerua atu pānga ngā kitea huaina nei tītohunga ko toronga tohu. Kia kite a he aha te tikanga o te reira. Ko te pānga kei e i roto i te tukanga o te tahuri te uara kotahi-paita i roto i ia moka o rua-paita paita feunga nui uara tautapa haina paraire o te paita iti. Huri i te reira i roto i taua mo te rokiroki o te hainatia maha o ngā pūāhua ka taea e koe te whakamahi i te paraire tiketike-kia. A, no te kore e puta ke tenei uara matua rawa.

waehere Grey

Tenei ahua o te tuhituhi, Ko te tino he kī kotahi-taahiraa. Ko, i roto i te whakawhitinga i tetahi uara ki tetahi kei te rerekē haere tetahi anake moka o ngā mōhiohio. Ko te hapa, ka pānui raraunga arata'i ki te whakawhitinga i tetahi tūranga ki tetahi ki te wa iti wāhikē. Heoi, whiwhi i te hua tino hē, ka te tino whakakorea te tūranga koki o te tukanga taua. Ko te painga o tenei waehere ko tona kaha ki te tapua te mōhiohio. Hei tauira, fulihi nga paraire tiketike-kia, ka taea e koe te huri noa i te aronga o te tohutoro. Ko e tika ana ki te tāuru mana o Hoapiri tenei. A, no te ai kia outputted tenei uara rite te mata maranga a hinga i tetahi tuaka tinana o te hurihanga. Mai te anake ā te mōhiohio tuhia i roto i te kī Grey pūāhua, e kore nei e mau te raraunga tau tūturu, i mua i hiahiatia te mahi anō ki te tahuri i te reira i mua ki te momotuhi rua noa. meatia tenei e te whakamahi i te transducer motuhake - pūwetewaehere Grey Binar. Kei te ngāwari te kitenga tenei pūrere i runga i huānga arorau timatanga e rua taputapu me ngā pūmanawa.

Grey waehere-Express

Grey Paerewa kī kotahi-taahiraa mō rongoā e kua aroaro i roto i te puka o tau, whakaarahia ki te kaha o rua. I roto i te wā i reira he mea tika ki te whakatinana i ētahi atu rongoā, o taua ahua o te record tarai me te whakamahi i anake te wahi waenganui. Ka rite ki te hua, kei te rongoa te kī kotahi-taahiraa. Heoi, i roto i tenei waehere tīmatanga awhe tau e kore te kore he. hünuku te reira ki te uara i tohua. I roto i tukatuka raraunga i runga i te ngātere i hanga e kai hawhe o te rerekētanga i waenganui i te taumira tuatahi, me te iti.

Tukunga o te tau hautanga i roto i te rua matua whakaritea-ira

I roto i te tukanga, to tatou ki te mahi e kore anake tau katoa engari hautanga ano hoki. Ka taea te tuhia e hāngai, kōaro me waehere atu taua tau. te hanga o te parau tumu matua whakahuatia ko te rite i o te katoa. Noa nei whakaaro matou e kia te wāhi pūtakerua te matau o te LSB. Otiia e kore e ko te take tenei. Ka taea te kei reira i runga i te maui, me te moka tino nui (i roto i tenei take, i te tāupe e taea te tuhituhi anake tau hautanga), me te tāupe waenganui (uara whakauru kia tuhia ai).

Māngai o binary mānu-ira

whakamahia ana tēnei puka te ki te tuhi tau nui, ranei hurihia - he iti rawa. Ka rite ki te tauira, tawhiti ranei rahi ngota interstellar me ngā irahiko. I roto i te tātai o enei uara e whai ki te tono i te waehere ā-rua ki te rere rawa nui. Heoi, e kore e tangohia e tatou ki pūkete te tawhiti rangi ki te mirimita e pātata ana. Na reira, he hauarea te ahua o te-ira whakaritea i roto i tenei take. Hei whakaatu i taua waehere whakamahia puka taurangi. Ko, te maha tuhituhi te rite te mantissa whakanuia e tekau ki te mana o te whakaatu i te tau kia hiahiatia. Me mōhio e kore te tikanga e nui atu i te kotahi te mantissa, a i muri i te ira kore kia tuhituhia ki te kore.

te reira ngā

Kei te whakapono te reira e whakaaro te tuanaki ā-rua i roto i te tīmatanga o te rau tau mathematician 18 Gottfried Leibniz i Germany. Heoi, ka rite ki te mea kua tata kaipūtaiao kitea, roa i mua i tenei o nga Maori o te motu Kiwa o Mangareva ki te whakamahi i tenei ahua o te tauhanga. Ahakoa te meka e Pākehā tata tino whakangaromia te pūnaha tauanga taketake, whakahokia nga kairangahau te pūtakerua matatini me ngā momo ira o pūkete. I tua atu, i te pūtaiao hinengaro Nuñez kerēme e whakamahia te waehere waehere ā-rua i roto i China tahito tae noa hoki rite te rau tau 9 BC. e. Ētahi atu u'i i tahito ra pērā i te Maya whakamahia hoki ira huinga matatini me ngā pūnaha ā-rua mō te aroturuki i'ai wa me ngā arorangi.
