Ä - he aha te mea te reira? hub pūrere

fifili maha iwi e pā ana ki te mea ä, me te aha pau ratou. Ko wai e tūhura i tatou i tenei take. I raro i te hub te tikanga i matau rite te kōpuku whatunga. kua he tikanga rerekē i roto i ngā ahumahi rerekē tēnei wā.

Mā te whakamahi i te hub i roto i ngā rāngai

Hei tauira, i roto i te tari ä kawe - he transplant kikī ranei kōpuku, ä. Ko te ahumahi pūngao ko te pokapū motuhake i roto i nei wehea kotahi ara ki te maha. Off-ara waka e huaina kupu ko mamau kotahi-ara tāutatia e te i runga i te auri mua. I roto i ngā whatunga Ipurangi whakamahi hoki ä. He aha te mea te reira ki "FidoNet" whatunga? Here hub - kōpuku, whakamahia nei te ki te whakawhiti mēra. Te whatunga tiritahi kōnae Direct Tūhono pera i huaina tūmau tukutuku.

Ko te ariā tino whānui whakamahia i roto i te hangarau rorohiko me te Internet. hāngai ana te huinga motuhake o te taputapu whatunga te i runga i nga mahi e hoatu i mua i te whatunga i āta whakamaheretia me te utu o te whakatinanatanga o rongoā motuhake. whakaaro tētahi āhuatanga nui o te taua raruraru ko ki hei te whiriwhiri o ngā pūrere, i roto i nei te whakatangihanga te tūranga matua e pouara, whakakā me ä. E ko, tamata tatou ki matau.

Tari ä i roto i ngā whatunga rorohiko

Constructing hangarau o whatunga rorohiko e tipu tonu. Pūrere e ko to ratou tūāpapa me whakamahia mō te kōrero i waenganui i rorohiko, ka karanga rerekē: he hub, he pana me te pouara. He aha te mea te reira, whakaaro tatou i roto i te taipitopito atu.

Ia o enei whakaaro ki te tākaro tona tūranga i roto i kōrero i waenganui i rorohiko i runga i te whatunga. Waho kia titiro ratou i te taua: pouaka whakarewa rahi iti o, he maha o tauranga me tūhono, e hono Itarangi-taura. Ki te whakaaro ki ngā ariā pērā i te pana, hub, hub, pouara, kei te maha whakamahia ratou rite taurite, engari ko te he hape tenei. enei whakaaro rerekē katoa.

hub

Ko tētahi o nga whakaaro whatunga tuatahi he ä. He aha e enei taputapu? Te wā he take Ingarihi. Ko te kupu ä ko te pokapū o te mahi. Hub, ranei hub, hangaia ki te hono rorohiko i roto i te whatunga hanga noa kotahi. Ko te pūrere whakarato he maha o ngā tauranga, e taea te hono i tetahi rorohiko whaiaro i runga i te whatunga. Nuinga o ngā wā e whakamahia ana mo tenei whakaaro, rua miro, ka romia e te i roto i te ara motuhake.

Ko te parau tumu whakahaere o te hub

A feruri i te parau tumu o te mahi o te hub whatunga. A, no te ngana ki te uru tetahi o nga rorohiko whatunga rite rawa ki te hub, ki tetahi atu rorohiko, kua tonoa te pūrere tuatahi ki te wāhitau o te hub whatunga wahi ngā o ngā mōhiohio i huaina pākete.

Whakamātauria ki matau i te tauira ara iahiko ki rorohiko toru. Tera pea te pūrere e piri rorohiko PC1, PC2 me PC3. Ko te tūranga o te hub takoto i roto i te uri o te pākete raraunga i te PC1 mā te whakawhitihia reira ki ētahi atu whakaaro, ngā ki te WLAN, arā, PC2 me PC3. I te wa o te whakauru ki te tohu rorohiko PC3, hoki i hangaia e ia, ka tukua te muri he hub hoki pākete. e tuku ana tēnei hub mōkihi ano rorohiko whatunga katoa rite te roa rite te whakautu i te PC3 kore e hoki ki te PC1 rorohiko te tuku.

he hoahoa hi'oraa maitai pērā o te atanga o rorohiko hono i roto i te whatunga rohe ki te hub. Ko te drawback matua o taua whatunga - tonoa rawa nui ngā mōhiohio kei te. Ko te hub whatunga tonu e tuku pākete raraunga ki ngā pūrere whatunga katoa, ara i roto i te hui i te ūnga ko hoki te PC motuhake. I te wa ano, rorohiko he mongamonga o te mōhiohio e he maha e kore e tino hiahia ana ratou. Kei te ata mohiotia te hangarau rawa utu nui i roto i. Ko te inaianei aha ä tata i roto o te whakamahi. I roto i te hokinga mai, whakawhanakehia ratou whakaaro ake mahara - whakakā whatunga, i roto i ngā mātapono noa tuku ki rite te pana.

whakakā

Ko te wā "pana" (pana) he āhua Ingarihi me whakawhiti tikanga, he pana whatunga ranei. Ka rite ki te whakakā hub hiahiatia te ki hono rorohiko i te whatunga rohe taua. Ko rerekē i te ara iahiko ki te hub whatunga Hononga hoahoa o te rorohiko. Engari o te PC hub hono ki te pana.

Ka rite ki te āhua tino rite ki te hub, he faufaa rerekē i reira he pana, ko te tikanga i nei tuku mōhiohio te i waenganui i rorohiko whatunga.

I muri i te fariiraa i te pākete mōhiohio i te rorohiko, pana whatunga, pērā kore e te hub tuku atu i te reira ki te PC katoa whai wāhi i roto i te kupenga, ka whakahaere te mōkihi whakamahinga ki te wāhitau ko reira te rorohiko, kua hangaia nei mo te wahi. Hei tauira, ina e tuku PK1 pākete raraunga ki PK3, whakarite pana te whakawhiti ki a ia, bypassing te PK2. PK3 whakautu pākete i te whakakā whatunga hoki ano ki te kōrero kaituku i roto i te ipu anake te - PK1.

Ko te pana e te āheinga ki te rokiroki i te wāhitau o rorohiko katoa e kua hono ki ona tauranga, a ko te kupu e taea te whakahaeretia e te mōhiohio mana, haere mōhiohio anake i runga i te PC ūnga me waiho ētahi atu.

Kua whakatakotoria iho te pūtake o te whakakā whatunga te tepu o motuhake MAC-wāhitau o te kaiwhakamahi taputapu whatunga i roto i te whatunga o waho, me te ā. Ka rite ki te hua, he pākete o ngā mōhiohio, tomo ia o nga tauranga whakawhānui rite ki te tepu ararere me te tukuna ki te wāhitau tauranga, te wahi i te taputapu e tika ana.

pouara

Ko te ingoa "pouara" hoatu ara ki te pouara Ingarihi. taea ki te whakarite i te whakawhitinga o te mōhiohio i waenga i Ngā LAN i rua, neke atu rānei rerekē tēnei pouara ko. I tua atu, i te pouara whakarato te tauranga e kua hiahiatia ki te hono i te reira ki etahi atu pūrere ki te taura.

Ko te parau tumu o te mahi o te pouara

Ka rite ki pupuri te whakakā whatunga he tepu mo te MAC-wāhitau, te pouara rite te tepu ararere pupuru ana i te tepu o IP-wāhitau. Ko te mahi matua o te pouara ko ki te rokiroki i te raraunga, me te mana kia mohio atu pouara te huringa i roto i te whirihoranga whatunga. Kei te kitea te reira e te whakamahi o ngā kawa ararere mō te ruruku ki ētahi atu pouara. A, no te riro koe i te pōkai i roto i te pouara whakamutunga whakamahi tikanga rerekē, me ngā paearu mō te whakatau i te mōhiohio ara ūnga pākete whakamua pai.

Ka taea te programmed te pouara ki ngā ture taumata-maha e kua whakaritea e te ihirangi o pākete o ngā mōhiohio e puta mai ana i a ia. programmed te pouara te ki te whakahohe i te pūnaha tiaki taputapu whatunga, whatunga fakamafola NAT-wāhitau, me te kia i te ratonga whatunga DHCP.

Ki te hau hinengaro, he pouara i roto i nga whakaaro whatunga tino mātanga. I tua atu ki te taea o anō i te pouara pākete mōhiohio waka e taea te whakamahi ki te whakaputa i te whatunga mana waka. I tua atu, kua ratou te kaha ki te tauhohe ki huringa i roto i te whatunga i roto i te aratau hihiri kimi hua ratou ona tātari pākete tiaki, te tātai pākete ki te aukati haere ranei.

USB-hub

I tua atu ki te tari ä whatunga Itarangi, whakamahia te wā "hub" kei roto i te USB hangarau. Ko te whanaketanga o te wahi taputapu titauraa tiketike hou i runga i te taumata o te whanaketanga o atanga kaiwhakamahi o taputapu rorohiko. He he momo o apatoko rorohiko ki te kia hono e te tikanga o te hononga USB, e titau te reira i te pūrere motuhake e taea ai e koe ki te hono ngā pūrere maha wā kotahi mā USB. Kei te karanga a te reira i te USB-hub. Pehea e mahi i te reira?
