He aha te mea he whakawaehere ā-rua ao? tikanga hōtaka

tukanga i te rorohiko i te nui nui o te mōhiohio. kōnae Ororongo, pikitia, kuputuhi - katoa e hiahia ana koe ki te tākaro whakaatu ranei. He aha ā-rua waehere ko te tikanga ao o hōtaka raraunga o tetahi taputapu hangarau?

He aha te mea rerekē i te whakamunatanga waehere?

E mea pinepine taurite iwi te ariā o "waehere" me "whakamunatanga", ka i roto i te meka i ratou tikanga rerekē. Ko te kupu, whakamunatanga ko te tukanga o te tahuri ngā mōhiohio i roto i te tikanga ki te huna i te reira. Wetemuna maha taea te tangata e puta ke te kuputuhi, ranei iwi rawa whakaakona. Kei te whakamahia waehere mō te tukatuka o ngā mōhiohio, me te noho o te whakamahi ki a ia. Kei te noa tepu Tapa noa whakamahia, waia ki te katoa. Kei te hanga te reira i ki tō rorohiko.

parau tumu waehere-rua

hāngai whakawaehere pūtakerua te i runga i te whakamahi o rua anake tohu - 0 me 1 - mō te tukatuka mōhiohio e whakamahia ana e te whakaaro rerekē. E huaina ēnei tohu mati ā-rua, Ingarihi - mati-rua, ranei moka. Ia o nga tohu o te waehere ā-rua noho mahara o te rorohiko ki te 1 moka. He aha ā-rua waehere ko te tikanga ao o te tukatuka mōhiohio? Ko te meka e ki te rorohiko māmā hapai i pūāhua iti. Mai tei me te kakama o te PC tenei: te mahi iti mahi e tika ana ki te mahi i te pūrere, te teitei te tere me te kounga o te mahi.

kitea parau tumu Tapa-rua te kore anake i roto i te hōtaka. Ki te whakarerekētanga o te reokore, me te drum e hamama ana patu Poronīhia tuku mōhiohio ki tahi i te tahi. tano te parau tumu rite i roto i Morse waehere, te wahi e whakamahia nga oro roa, me te poto ki te tuku i te karere. "Tātai Telegraphic" whakamahia tenei ra.

Hea ki te whakamahi i te whakawaehere-rua?

Ko te ā-rua waehere o ngā mōhiohio e whakamahia ana i roto i te rorohiko te wahi katoa. Ia kōnae, ahakoa he reira waiata kuputuhi ranei e kia programmed kia e taea muri kia ngāwari whawha reira, ka lau. he pai hoki te mahi ki te tohu, me ngā tau, ngā kōnae oro, whakairoiro pūnaha Tapa-rua.

whakawaehere ā-rua o ngā tau

Na e māngai tau rorohiko i roto i te puka ā, hano ki te tangata toharite. Ko te whakamahi o ngā tau Arabic, rite whakaaro tatou, mo te tikanga koretake. Ko te take hoki tenei ko te hiahia ki te tautapa i te tau ahurei ki ia pūāhua aha ki te mahi i nga wa e taea.

E rua ngā pū: tū me te nepozitsionnyh. hāngai ana pūnaha Nepozitsionnyh te i runga i te whakamahi o reta Latin me waia ki a tatou i roto i te ahua o tau Kariki. Ko te tino uaua ki te matau tenei tikanga tuhi, reira, i whakarerea.

pūnaha tau tū whakamahia tenei ra. Ko ētahi o ēnei-rua, ira, ā-waru me te hautekaumāono Tapa noa ngā mōhiohio.

pūnaha Tapa Decimal whakamahi tatou i roto i te ora ia rā. Ko reira mua hoki tatou nama Arabic, e he mahino ki te katoa. whakawaehere-rua tau rerekē te whakamahi i anake kore me kotahi.

E tahuri tau tōpu ki waehere-rua mā te wehewehe ratou e 2. Ko te hua te kanohi wehea ano ki e rua ngā wāhanga, he hopea 0 ranei 1. Hei tauira, te tau 123 ₁₀ i roto i te momotuhi ā-rua taea te māngai i roto i te puka ₂ 1111011 noa. He maha: 20 ₁₀ 10100 ka titiro rite _2.

Rārangi 10 me 2 e denoted tau aua ā-rua, me te ira o Tapa pūnaha. whakamahia tohu waehere ā-rua te ki faaohie mahi o te uara aroaro i roto i ngā pūnaha tau rerekē.

hāngai tikanga hōtaka tau ira e i runga i te "ira mānu". I roto i te tikanga ki te tika whakawhiti te uara i ira ki te pūnaha waehere pūtakerua te whakamahi i te tātai N = M x qp. M - Ko te mantissa (waho te faaiteraa o tetahi tikanga), p - ko te tikanga o nga uara o N, me te q - turanga Tapa pūnaha (i roto i tenei take 2).

E kore e pai tau katoa. I roto i te tikanga ki te wehewehe i waenganui i ngā tau pai, me te kino, rau te rorohiko te wahi o te 1 moka ki whakawaehere te tohu. Tenei kore Ko te tāpiri, me te wae - tango.

Mā te tenei pūnaha taua hanga e mea ohie mo te rorohiko ki te mahi ki tau. Ko Ko te aha te mea ao te waehere ā-rua, ka rorohiko tukanga.

whakawaehere ā-rua o te kōrero tuhi

Ia tātai ā huinga pūāhua o ona ngā kore, me te hunga. Kei te kuputuhi o pūāhua rerekē: reta (pūmatua, me te pūriki), tohu tauhanga me ētahi atu uara ngā. titau te whakawaehere o ngā mōhiohio tuhi te whakamahi o waru uara ā-rua karapīpiti i 00000000 ki 11111111. Ko te kupu ko reira taea ki te tahuri i te pūāhua rerekē 256.

Ki te karo te whakama i roto i te waehere o te kuputuhi, te whakamahi i te tepu motuhake o ngā uara mō ia pūāhua. tapaea ratou te Latin tātai reta, tohu tauhanga me tohu o te whakaaro motuhake (hei tauira, €, ¥, ©, me ētahi atu). Tohu āputa 128-255 whakawaehere rārangi pū motu te whenua o.

Hei whakawaehere tohu titau 1 8 mahara moka. Hei te faaohie e rite ki te 1 paita podstchetov 8 paraire, na whanganga te mokowā kōpae katoa mō ngā mōhiohio kuputuhi e i roto i paita.

E rite rawa te nuinga o rorohiko whaiaro ki te tepu paerewa o te ASCII (American Paerewa Pārongo mō te Waehere). Kei te whakamahia hoki atu tepu, i roto i nei te pūnaha waehere o ngā mōhiohio tuhi e faikehekehe. Hei tauira, te whakawaehere pūāhua mōhiotia tuatahi ka karanga a Koi-8 (Code mō bit-8 Whakawhitinga Pārongo), ka mahi i te reira i runga i te rorohiko UNIX OS. hoki e whānui kitea waehere SR1251 Ripanga, i hanga hoki te pūnaha whakahaere Windows.

waehere ā-rua o oro

Ko tētahi atu take he aha te waehere ā-rua ko te tikanga ao o te hōtaka raraunga - ko tona tapatahi, ka mahi ki te kōnae ororongo. Tetahi waiata ko ngaru oro o rerekē tīwera me te auautanga o te oscillation. pā ēnei tautuhinga i te rōrahi me te ware.

Hei hōtaka he ngaru oro, tuwhaina e te rorohiko reira ki te maha nga wahi herenga, ranei "tauira". kia kia nui te maha o taua tauira, na reira e 65536 ngā rerekē o ngā kore, me te hunga. Fakatatau ki ai, E rite rawa rorohiko hou ki moka-16 kāri tangi e te tikanga te whakamahi o 16 mati ā-ki te whakawaehere te tauira o te ngaru oro.

Hei te tākaro i tētahi kōnae ororongo, tukanga te rorohiko te raupapa programmed o waehere ā-rua, me te fakatahai ratou ki tetahi ngaru tonu.

Tapa ngā tūtohi

Ka taea te aroaro mōhiohio kauwhata i roto i te puka o whakairoiro, hoahoa, whakapakoko whakaatakiriata ranei i PowerPoint. hanga ia pikitia e ake o ira iti - pika e taea te peita i roto i te tae rerekē. whakawaeheretia te tae o ia pika te ka rongoa, a te mutunga whiwhi tatou i te whakapakoko ki tonu i.

Ki te he pango me te ma o nga pikitia, kia kia ia waehere pika rānei te kōwae te kore ranei. A, no te whakamahi i wha tae, te waehere o ia o ratou ngā o ngā tau e rua: 00, 01, 10 11. ranei E ai ki tenei parau tumu te wehewehe kounga o tetahi tukatuka image. Whakanuia te whakaiti Kei te hoki pāngia te wherikotanga i te maha o ngā tae i whakamahia ranei. I roto i te take pai, titore te rorohiko āhua 16.777.216 tae.

mutunga

He tikanga rerekē o ngā mōhiohio hōtaka, tae atu whakawaehere pūtakerua ko te whai hua tino. Anake e rua tohu - 0 me 1 - ngāwari rorohiko pānui te nuinga o ngā kōnae. Ai ko nui teitei te tere tukatuka atu e kia whakamahia, hei tauira, papatono te pūnaha ira. Ko te tapatahi o tenei tikanga hanga mahuinga reira mo tetahi hangarau. Ko Ko te aha te mea ao i roto i ona hoa te waehere pūtakerua.
