He aha te mea te raraunga keteroki me Keteroki?

Rorohiko, aue, kihai i puta ia tonu te whakahau, e kua riro i te iwi. Ki te whakatere i tēnei tukanga whakamahi i te momo o tinihanga, a ka no te whakapehapeha o te wahi i roto ia ratou ki te Keteroki. He aha te mea te reira? He aha e nga raraunga keteroki? Kia pehea te e tenei tukanga mau e wahi? He aha keteroki te raraunga i roto i te atamai "Samsung", hei tauira, ka rerekē ratou ahua i te hunga i roto i te rorohiko? Kia whiwhi a raro, ki te whiwhi whakautu ki ēnei pātai.

He aha te mea keteroki?

Na ka karanga moka takawaenga, e whakarato ana te uru tere ki ngā mōhiohio, te tūponotanga e te uiui runga ake te katoa. raraunga katoa i roto i roto i reira. He painga nui ko e unu i te mōhiohio e tika ana i te keteroki taea e tino tere atu i i te taonga taketake. Ko reira te mea he drawback nui - te rahi. whakamahia raraunga keteroki te i roto i ngā pūtirotiro, kōpae mārō, PTM, tūmau tukutuku, WINS, me ngā ratonga DNS. Ko te pūtake o te hanganga ko nga recordsets. e pā ana ia o ratou te ki te tetahi huānga wae raraunga ranei e protrude tārua te mea kei roto i te mahara matua. Tāurunga i te pūtāutu (TAG), i te tikanga o nei takoto e mo. Kia titiro a te wāhi rerekē moka iti o te tirohanga: he aha te keteroki raraunga i roto i to koutou waea "Samsung" ranei tetahi atu kaiwhakanao? He rerekē i te hunga e te hunga i roto i te rorohiko ratou? Mai i te wāhi taketake o te tirohanga - e kore anake te rerekētanga i roto i te rahi.

Ko te tukanga o te whakamahi i

A, no te he kiritaki (e whakarārangitia ratou i runga) tono raraunga, te mea tuatahi e hanga he rorohiko - titiro te keteroki. Ki te hiahiatia te reira urunga, na te whakamahia reira. I roto i enei wā i reira he he hit. Wā te raraunga tārua i te keteroki ki te mahara matua. Otiia ki te kahore i kitea te record hiahiatia, i reira te mea he ihirangi rapu i roto i te turanga rokiroki. tango katoa whakawhitia te mōhiohio e ki te keteroki, kia e reira ka taea te uru hohoro atu. Te ōrau o ngā tono, ka karaunatia ki te angitu, ka karanga te taumata ōwehenga hit ranei.

whakahōu raraunga

A, no te whakamahi i, mo te tauira, tirohia te pūtirotiro tukutuku te keteroki rohe ki te kitea he tārua o te whārangi. Homai nga whāititanga o tenei momo mahara, faaoti i te ma'iri te ki tūraki te mōhiohio ki te hanga wāhi. Hei whakatau rite te mea e kia whakakapia, te whakamahi i hātepe rerekē displacement. E te ara, ki te kōrero tatou e pā ana ki te meka i keteroki tenei raraunga ki te "Android", e hoki te wahi tino e whakamahia ratou ki te mahi ki whakapakoko, me raraunga tono.

tuhituhi Kaupapahere

I roto i te whakarerekētanga o te tirotiro o te keteroki, me te whakahou i te raraunga i roto i te mahara matua. Ko te roa te wā e haere i waenganui i ngā mōhiohio tono i runga i te kaupapa here tuhi rānei. E rua ngā momo matua:

1. tuhi Inamata. tuhia i ia huringa e synchronously ki te mahara matua.
2. Roa writeback ranei. puritia ia wā Whakahōu raraunga, ranei ka tonoa e te kiritaki. Hei pupuri i ara o ranei i whakatikatikaina ai ki te whakamahi i te tohu ki āhua e rua: "paru" whakarerekē ranei. I roto i te take o te ma'iri e taea te hanga e rua tono hāngai mahara matua: kua whakamahia te tuatahi ki te tuhi i te raraunga e kua puta ke i te keteroki, me te tuarua - ki te pānui i te tūemi e hiahiatia ana.

kia ai taua mea penei e riro kotiti ki te moka takawaenga mōhiohio. Tenei puta ka te raraunga i roto i te mahara matua, kahore hanga i tetahi whakatikatika ki te keteroki. Hoki te ōritetanga, katoa o te tukanga whakatikatika mā te whakamahi i te kawa arotau.

tamataraa nāianei

Ki te hua i roto i te auau o pūtukatuka me mahi mahara nui haere, he wāhi raruraru hou - nga whāititanga o te atanga whakawhiti raraunga. He aha kia kite i te tangata mōhio? Ko te tino whai hua te pūmahara keteroki ki he iti iho i te RAM i roto i te pūtukatuka te auau. He tokomaha o ratou i to ratou ake moka takawaenga ki te whakaiti i te wā uru ki te mahara, i te mea pōturi ake i rēhita. Ko te PTM e tautoko mariko whakatutuki, maha tuu moka translation wāhitau iti, engari rawa nohopuku. Otiia i roto i te tahi atu te wā, e kore he tino whai hua te keteroki, a ētahi wā anake hanga raruraru (engari he reira te tikanga i roto i nga rorohiko, e kua oti te putanga kore-ngaio). Korero o te mea kua keteroki raraunga i roto i to koutou atamai, tuhia NGO e tika ana ki te rahi iti o te pūrere he tika ki te waihanga whakatinanatanga keteroki iti hou. Na e taea etahi waea whakamanamana tawhā rite kotahi tekau nga tau ki muri, rorohiko matatau - engari he aha te rerekētanga i roto i to ratou rahi!

Tukutahi raraunga i waenga i ngā moka rerekē

He whai hua te keteroki ka kotahi, ka pehea ki te mau tonu i te whai huatanga o tenei hangarau, ki te he rota o ratou? faatiti'aifarohia tēnei raruraru te moka coherency. E toru ngā kōwhiringa mō te utu raraunga:

1. Urutomo. Ka taea e te keteroki tikanga rite rite koe.
2. Tāuke. Hangaia hoki ia take motuhake.

1. L1 keteroki. Ko te taumata keteroki tere - tuatahi. I roto i te meka, he reira wahi o te pūtukatuka rite te tū ki runga ki te maramara kotahi, a ka pā ki te poraka mahi. Ko te tikanga wehea ki e rua ngā momo: ako keteroki me raraunga. e kore e mahi te nuinga o pūtukatuka hou kahore tenei taumata. mahi tenei keteroki i te auau pūtukatuka, na te tohutoro ki reira kia mahi ia huringa karaka.
2. L2 keteroki. Ko te tikanga kei tahi ki te kotahi o mua. He wāhi mahara motuhake. Hei kitea i roto i ona uara, e hiahia ana koe te rōrahi katoa, hoatu i raro i raraunga Keteroki, wehea e te maha o otaota, i te mea i roto i te pūtukatuka.
3. L3 keteroki. Puhoi, engari te keteroki ti'aturi nui. Nuinga, neke atu i te 24 MB. Kei te whakamahia te reira ki te tukutahi i te raraunga riro i keteroki o rerekē te taumata tuarua.

Ki te whakarite tatou ko o te rōrahi taua engari associativity rerekē, te tetahi ki nei i ia he pai ai nui ki te mahi iti hohoro te pūreirei takawaenga, engari ki te tōtika nui motuhake.

mutunga

Ka rite ki a koutou e taea te kite, te raraunga keteroki i raro i etahi tikanga, ka taea tō rorohiko ki te mahi hohoro atu. Ko, Aue, i reira te mea tonu he rota rawa o ngā āhuatanga i runga i e taea e koe te mahi mo te wa roa.
