Ko te tere mōrahi o te Internet, tapaea roto te hangarau hou

Ko tētahi o nga pātai mau rave'a ohie, ki nei kahore he kupu whakahoki äta e whai ake: "He aha te mea te tere mōrahi o te utu raraunga mamati i waenganui i nga pūnaha rorohiko e rua?" Hei tauira, kua mohiotia taua mea e kua i roto i te anga o te tikanga Japanese o whakawhiti raraunga whakamātautau kua mahia i waenganui i rorohiko i kīia o neke atu i rua terapaita ia te rua (20 terabits ia 2012). Heoi, he tiketike rawa te utu o te whakatinana i te otinga taua, e kore nei e hanga i te pāpāho hangarau. he hua pai taua ko te rota o ngā pūnaha rorohiko motuhake me Momo taputapu whatunga. He hiahia ake i roto i te pātai o te mea ko te tere mōrahi o te Internet, te kotahi ara e whakaarohia ana ranei tetahi atu kaiwhakarato nga rangatira rorohiko noa.

Me

Kei te piki haere te rōrahi o ngā pūmanawa hou me ngā kōnae rongorau i te tere maere. Hei tauira, ki te whakanohoia te tohatoha o te pūnaha whakahaere Windows XP mohiotia te i runga i te CD 700MB paerewa, e rapu DVD (wāhanga tino ranei) putanga muri. E mea papû e i roto i te tikanga ki te whakaiti i te wā pau i runga i whakawhiti raraunga , kua ki te kia nui haere te tere mōrahi o te whatunga. Te kore, te mahi ki te maha ngā rauemi whatunga taea riro te tumanako mārō o te otinga o te tukanga whakawhiti.

ADSL tere mōrahi

Kotahi hangarau, e te tonu whānui e whakamahia ana e te tahi mau kaiwhakamahi, he ADSL tenei. Ko te whanaketanga momo hononga waea-ake. whakamahi te reira i te rārangi waea ngā. kaiwhakarato PBX ki te whakaturia te pūrere motuhake - DSLAM. Kaitango mo tona wahi hono ki te rorohiko te pouwhanga tika. DSLAM Ko te takawaenga i waenganui i te utu me te taputapu kaitango. Ina whakaritea ki te motuhake rongoā taura painga ko e ki te whai koe i te waea founu, me he kaiwhakarato tika, e taea te kawea te hononga Ipurangi i roto i rite wawe tonu.

Ko te tere mōrahi o te whakatau taua tei runga i te āhuatanga o te aho, mahere, me te taputapu āheinga. Ko te kupu, mo te ADSL paerewa ITU G.992.1 Annex A (B) «tuanui" tere werohia he 12 Mpiah, me hoki - 1.3 Mpiah (hongere tukutahingakore tonu). Ko mo te ADSL2 otinga ake + (aratau ITU G.992.5 Annex M) auau nui haere ki te 24 / 3.5 Mpiah, aua. Ka taea e te nuinga o ngā kaiwhakamahi te kāinga whakawhirinaki i runga i 8/1 Mpiah i pai.

orotahi whaiaho

I tēnei wā, ko te rongoā atu rongonui i runga i te pūtake o te rua miro me ngā hononga optical. I roto i te take tuatahi, e tuku te whakahiko parahi o te raraunga taura i reiti ki runga ki te 100 Mpiah. tere Gigabit wātea ki ngā kaiwhakamahi noa varavara rite whakaritea whāititanga i runga i te roa o te wahi taura i te dispenser ki te rorohiko kaitango. He nui atu mātanga raina hanga i runga i te pūtake o ngā rārangi optical taea tuku haere te muka i te iti rawa 10 GB o raraunga, ka hoatu te taea o whakakiato i te maha o takere i te muka kotahi, e taea ana te ruri te auau tuku katoa terabits. A, no te tūhono ki whatunga whatu muka nuinga whakaratohia e te kaiwhakamahi 100 megabits ki 1 gigabit.

hononga ahokore

Ngā mihi ki te tini o ngā pūrere kōrero kawe hoki maha moni motuhake ko te tū te pātai o te mea ko te tere mōrahi o Wi-Fi. I tēnei wā ko reira ki runga ki te 140 Mpiah (ara mo ngā pūrere 802.11n kī 300 Mbit / s). pānga nui i runga i nga kaha tere o ngā rārangi kōrero ahokore i mau fifi (taiepa, me ētahi atu) He i waenganui i nga whakaaro.
