He tikanga o te whakawaehere mōhiohio mā te whakamahi i ngā tau. whakawaehere-rua

I roto i te tukanga o te whanaketanga o te tangata kua tae mai ki te ite i te hiahia ki te tiaki me te haere i runga i te tawhiti atu mōhiohio ranei. I roto i te take whakamutunga i hiahiatia ai ki te whakaahua ke ki tohu. huaina ana tēnei tukanga ko te whakawaehere raraunga. mōhiohio kuputuhi, e taea te puta whakairoiro me te kupu ki tau. Mō pehea e taea e koe i te reira, parau te reira i to tatou tuhinga.

Ko te tuku o te mōhiohio i runga i te tawhiti

Hei kawe i te kōrero i te kaituhi ki te kaiwhiwhi (i puna ki te kaiwhiwhi), te tino whakamahia nuitia e toru ngā momo o ngā pūnaha tuku:

• karere-pou;
• acoustic (hei tauira, mā te kaikōrero);
• i runga i te pūtake o te tikanga o te torotoro waea (waea, reo irirangi, optical, ngaruiti tānga, amiorangi, te muka whatu).

Ko te tino noa i te kau e o te momo muri o te pūnaha tuku. Heoi, titau ratou whakamahi whakamahi mua tetahi te atu ara o whakawaehere mōhiohio ranei. Ki te tau i roto i te momotuhi ira mua o te tangata hou ki te hanga i te reira tino uaua.

whakamunatanga

I te tahi taime te karere e hiahia ana koe ki te huna i ihirangi i tangata ke. I roto i tenei take, whakamahia whakamunatanga te. kia whakamahia ai tenei ngā tikanga o whakawaehere mōhiohio mā te whakamahi i ngā tau.

pūnaha tau ā-rua

I te ata o te wā rorohiko, he āwangawanga e pā ana ki te rapu hoki i te pūrere e e tukua rite tohu noa tau i roto i te rorohiko pūtaiao. whakatau te take i ka whakaarohia Claude Shannon ki te whakamahi i te pūnaha tau ā-rua. Kua mohiotia te reira mai te rau tau 17, ka i hiahiatia mo tona whakatinanatanga te pūrere ki te āhua pūmau rua e ōrite ana ki arorau "1" me te arorau "0". i i taua wa i mohiotia e ratou ki te hira - i te matua, e taea e rānei magnetized demagnetized ranei, ki te transistor e taea e rānei tuwhera kati ranei.

Ko nga painga o te pūnaha taua pūtakerua pā ki te noho pai o te tātaitanga e taea te whakamana i runga i tau kei ngā i roto i te momotuhi takirua.

Ka rite ki tahuri te "auau" ngā mōhiohio i roto i te puka e tika ana mō te tukatuka rorohiko me te rokiroki

whakatinana Rorohiko waehere ā-rua kei te tū i te aroaro ngaro ranei o ngātere i te huānga rokiroki mōkitokito. kia ēnei ngā:

1. ngātere Photo-optical. Ko te mata o tetahi kōpae whatu (DVD, CD, BluRay ranei) ngā o te tōrino i hanga i wāhanga iti. Ia o ratou rānei marama ranei pouri i roto i te te tae. A, no te huringa i te kōpae i roto i te puku, arotahi tona ara tōrino taiaho. taka tona whakaaro i runga i te pūtau solar. Ko te whakamutunga i roto i tenei take ko te kōrero te kaiwhiwhi. whakaata wāhi tōrino kanapa marama, me te haere i te reira ki runga ki ki te pūtau solar, pouri, i runga i te anga ke, mimiti marama. Ka rite ki te hua, e tango te photocell mōhiohio whakamuna i te ara o te kōpae rite wahi pouri, me te marama.

2. Ko te ngātere autō. Ki te to ratou awhina, whakawaeheretia mōhiohio i runga i te puku mārō, kei nei i roto i te pereti tere tītaka. Ka rite ki i roto i te take o te kōpae whatu, te mata katoa - tōrino, e ngā o te raupapa o ngā wāhanga iti i roto i te nui o te maha miriona. Ia o ratou ko te mema i te mea nehenehe o te fariiraa i tetahi o āhua e rua: ". Kore-magnetized" "magnetized" ranei ahua ai ratou he waehere ā-rua o te kōrero ngā. "Aperaa", kawea te huru o te huānga raima e te matenga motuhake e neke haere te mata pereti.

3. Ko te ponana hiko. RAM Ko te maramara rorohiko e ngā o milioni o ngā pūtau iti, "kohia" i ngā pūnga mōkitokito me transistors. pea kei takitaha o ratou he tiaki hiko kia uncharged ranei. Ngā o ngā pūtau mahara i te hunga i roto i tetahi o nga āhua taea e rua, i whai ahua ai te waehere ā-rua. I roto i te tahi atu pūrere katoa i runga i te pūtake o te maramara mahara, pērā i te puku kohiko, SSD-kawe, a pera atu., Te mōhiohio rongoa i roto i te ara ano.

Whakawaehere kuputuhi

Ka rite ki kua whakahuatia, tetahi o nga momo o raraunga faafariuraa mō te tuku me te rokiroki whakamuna te. Kei te whakamahia te reira ki te tiaki ki te whakaurunga. I te tīmatanga, ko te whakamunatanga me tikanga atu i tahito ra i whakamahia te mōhiohio Tapa e whai ake nei:

• Na roto i Polybius tapawha ko te tepu tuhituhi i runga i nei i roto i te tetahi tikanga te tātai reta Kariki katoa. whakakapia ia reta o te karere e te rua o ngā tau e tohu ana i te maha o tīwae me nga rarangi.
• Na roto i Alberti kōpae arā, o rua porowhita concentric. i whakapangia ratou reta me ngā nama. whakanohoia e ratou tetahi ki tetahi i roto i te rārangi mā te tītaka kōpae.

hāngai ana te tikanga hou o te whakawaehere kōrero kuputuhi i roto i te rorohiko kei i runga i te mau parau tumu ōrite. Hoki tona whakatinanatanga, ia huru o te tātai reta hāngai ki te tetahi tau tōpū. Na ka te iritihia te reira ki waehere ā-rua. E waru paraire hanga reira taea ki te whakawaehere 256 pūāhua rerekē. Ratou nui ki te tohu i te pukapuka katoa o te Ingarihi me reo Russian, tae atu ki ngā pūāhua pūmatua tauhanga me faatomaraa, me te tahi mau pūāhua motuhake noa.

I tēnei wā e kore pūnaha ASCII whaimana. Hoki tona codebook whakaritea 2. O enei, tautuhi te turanga te uara i te 0 ki te 127, me ngā tau roa kanohi e 128 ki te 255.

Kia pehea te ko te waehere o whakapakoko taetahi i runga i te rorohiko

Tetahi whakapakoko pango-a-ma tāngia i runga i te pepa i raro i whakanui karaihe puta rite te huinga o ngā e kua huaina Raster. Linear faaau a taea te faaite wherikotanga o ia i roto i ngā o tau tōpū. Tenei te tikanga e taea te whakamahi i te waehere ā-rua ki te rastirovaniya image. He noa fakatātā whakaaro tēnei wā kanohi taetahi rite te huinga o te maha nui o pika ki 256 hurihurihanga o hina. Hoki tau wherikotanga waehere o tetahi o ratou e rapu te tau moka-waru-rua.

Māngai o te tae pikitia

Ko ahua ake uaua te tikanga o whakawaehere pārongo mā te whakamahi i te maha o taua whakapakoko e mohio. Ki tenei mutunga, e hiahiatia ana i mua-, rite ki te hua o to ratou Mixing i roto i hanganga tino taea whiwhi i tetahi hue mohio a e te tangata kanohi image whāwehe ki 3 tae taketake (matomato, whero, me te puru). Tenei tikanga o Tapa whakapakoko te whakamahi i tau mā te whakamahi i 24 paraire huaina RGB, tae tonu (Tae True) ranei.

Ki te tae mai te reira ki te tā, whakamahia e te reira i te pūnaha CMYK. Kei te hāngai te reira i runga i te whakaaro e taea ia o te wāhanga tuatahi RGB pāhono te tae ngā reira ki ma. Ko ratou Urikiko, Kurauri me te kōwhai. Ahakoa he rawaka, i roto i te tikanga ki te whakaiti i ngā utu tā ratou, ka tapiritia he tuawha wāhanga - mangu. Ko te kupu, ki te tohu whakairoiro i roto i te pūnaha CMYK titau 32 mati-rua, a ka huaina e ia te aratau tae-tonu.

kanohitanga o oro

I runga i te pātai o mehemea i reira he ki tenei tikanga o te whakawaehere mōhiohio mā te whakamahi i ngā tau, kia waiho te whakahoki ae. Heoi, i te kau e kore e taua mahi e whakaaro tino. Ko ētahi o ēnei:

• tikanga FM. Kei te hāngai te reira i runga i te whāwehe o tetahi tangi matatini ki te raupapa o tohu ngaru pūmotu o iarere rerekē e taea te whakaahuatia e te waehere.
• tikanga Ripanga-poipoi. Ko te tepu i mua-hangaia rongoa tauira - tauira o ngā oro o rerekē mea whakatangi. Numbers, faaite te momo o te taputapu me te tauira tau, te ware, kaha, me te roanga o te tangi, a na i runga i.

Na e matau ana koutou e te whakawaehere ā-rua - tetahi o nga ara tino noa o te whakaatu mōhiohio, i te whakatangihanga a te wāhi nui i roto i te whanaketanga o te hangarau rorohiko.
