Whatunga uru hōkaiipurangi

Ki te tini whānui o whatunga rorohiko , te wā "hōkaiipurangi" ka mohiotia ki te katoa. A, ki te ko pono ariā te moni mua, engari inaianei he rerekē katoa. Kia matau ki ta takoto i muri i nga kupu "hōkaiipurangi whatunga" e āhei ki a koutou te whiriwhiri i te kaiwhakarato ratonga e wātea ana pai (ka huaina i pā ki te whatunga rohe me te Internet), kia rite ki te pai kia rite ki te ara tino pai ki te whakaturia ake tetahi mahi ki te whatunga.

I mua i ruku matou ki te ariā, whakaaro he āhuatanga mahi, e, aue, maha anga kaiwhakamahi Ipurangi noho i roto i te whenua Soviet Union mua. Ka rite ki matau koutou, ina hono koe ki te kaiwhakarato ratonga uru whatunga i roto i to ratou mahere tāke tohu tere ki te kuhimua "ki runga." Hei tauira, "ki runga ki te 10 MB / s", "ki runga ki te 50 MB / s," etc.

I roto i te meka, te kaha o te awa me te rahui hono. A feruri i te āhuatanga e i etahi wāhi i roto i te wa ki te whatunga te kaiwhakarato o te ratonga hono te kaitango. Ka rite ki te tikanga, whakarato reira tere utu tonu. I roto i te whai o ngā whāinga ōhanga, tonu te kaiwhakarato kamupene ki te riro kaiohauru hou. Ka rite ki te hua, riro te reira i te āhuatanga tūturu, ka i te wa taua kōkiri i te hononga ki te rota o ngā kaiwhakamahi ipurangi. Kotahi utu here "50 MP", tetahi, he toru ...

Ko te putanga arorau - te auau taka o te katoa kī i raro (mahara te kuhimua "ake"). Timata waea kaiohauru 'oi'oi i, raruraru noa ki kōrero, me te pera i runga i. I roto i te whakautu, whakahuatia te tautoko e he iti te hōkaiipurangi. He pono, he maheni ki kaiwhakamahi maha tenei. Mō te mea ko reira me aha taka te tere?

I roto i te 1920, he kairangahau American Ralf Hartli hikohiko me te ahupūngao Garri Nikvist, whakatutuki i te take o te whakawhiti kōrero i roto i te Telegraph, whakatakoto nga āhuatanga matua o te tukanga whakawhiti raraunga. Ko tētahi o te nui tino - ko te hononga i waenganui i te auau o te tuku, me te wā. Ko te kupu, whakatakoto Hartley ture rite ki ai te tapeke o te hautanga raraunga tuku ki te auau tuku whakamahia me te mahi wa. I te tau 1927 ua haamaramarama godu Nyqvist e he iti ki rua te auau whakamahia (te tikanga tuku, kahore ngaronga o ngā raraunga ia wā wae) te uara nui tuku. haapoto anake nga hua o to ratou mahi, whakatakoto te ariā i roto i te tau 1940, Shannon raraunga me te ariā o "hononga hōkaiipurangi."

Te awhe auau huaina whakamahia mō te tuku o te mōhiohio hongere ko "hōkaiipurangi". Mai i ture tauwehe o Shannon whakaatu e whakatutuki i te tere mōrahi taea e te whakanui ake i te mana tohu, hōkaiipurangi, whakaiti i haruru haavare no. tere nui ake e te tohu puoro he uaua, mai ina heke te whakanui ake pini te tau tapeke ia wa wae, a i roto i raungaitinga mā te whakaiti i te roanga o te rere kotahi faarahi i te nui o mate i roto i te pēne. Ko te tikanga, tatau te whanui pini e te tātai whakaaro te auau tīpakohia.

Me kï reira e te kaha hongere ngā kore anake te tohu e hiahiatia ana, engari ano hoki haruru. kia pokanoa hiko, nga āhuatanga o te kaiwhakahaere, tukanga whakaata Gauss tenei a na i runga i. Ka whiwhi te kaiwhiwhi te rere tonu o tohu, me te whiriwhiringa o roto i te wae e hiahiatia ana.

E hoki ki te tauira: ka tae tere te maha nui o kaiohauru te rohe o te katoa awa raraunga ki te auau tuku whakamahia e te kaiwhakarato (rārangi whatu, hono irirangi, parahi waea). Hei whakatau i tēnei raruraru, ake i te mana tohu ki te huri i te auau tuku me te taiao (utu rite titau te reira i te ao hou, o te taputapu), ranei ki te aukati i te rere o ngā raraunga i ia kaitango e kei te mahia.
