He aha te pouara?
Ko ngā pouara te nuinga o te wā e whakamahia ana i roto i ngā whatunga rohe me ngā whatunga whānui. Ka taea e ia te hono i ngā whatunga maha, i ngā wāhanga whatunga rānei, hei "whakamāori" i ngā mōhiohio raraunga i waenga i ngā whatunga rerekē, i ngā wāhanga whatunga rānei, kia taea ai e rātou te "pānui" i ngā raraunga a tētahi ki tētahi, hei hanga i tētahi Ipurangi whānui ake. I taua wā anō, he mahi anō āna pēnei i te whakahaere whatunga, te tukatuka raraunga, me te hononga whatunga.
He aha te pana
He whakarāpopototanga noa iho, ko te pana, e mōhiotia ana ko te pokapū whakawhiti. Ko te rerekētanga mai i te pouara ko tana taea te hono atu ki te momo whatunga kotahi, te hono atu ki ngā momo whatunga rerekē (pēnei i te Ethernet me te Ethernet Tere), ā, ka hanga i ēnei rorohiko hei whatunga.
Ka taea e ia te tuku tohu hiko me te whakarato ara tohu hiko motuhake mō ngā pona whatunga e rua e hono ana ki a ia, mā te reira ka karohia ngā pakanga tuku me ngā tauranga, ā, ka whakapai ake i te whai huatanga o te whakamahinga whānui.
Ko ngā pana noa ko ngā pana Ethernet, ngā pana whatunga rohe me ngā pana WAN, tae atu ki ngā pana muka whatu me ngā pana reo waea.
Te rerekētanga i waenga i te pouara me te pana:
1. Mai i te tirohanga mahi, he mahi waea mariko kei te pouara, ka taea te tuku aunoa i te IP. Ka taea e ngā rorohiko e hono ana ki te Ipurangi te tohatoha i tētahi pūkete whānui i runga i te pouara kotahi, ā, kei roto ngā rorohiko i te whatunga rohe kotahi. I taua wā anō, ka taea e ia te whakarato ratonga pareārai. Kāore he ratonga me ngā mahi pēnei i te pana, engari ka taea e ia te tuku tere i ngā raraunga ki te pona ūnga mā te matihiko whakawhiti ā-roto, ā, ka penapenahia ngā rauemi whatunga me te whakapai ake i te whai huatanga.
2. Mai i te tirohanga a te mea e tukuna ana ngā raraunga, ka whakatauhia e te pouara ko te wāhitau mō te tuku raraunga e whakamahi ana i te tau ID o tētahi whatunga rerekē, ā, ka whakatauhia e te pana te wāhitau mō te tuku raraunga mā te whakamahi i te wāhitau MAC, i te wāhitau ā-tinana rānei.
3. Mai i te taumata mahi, ka mahi te pouara i runga i te wāhitau IP, ā, ka mahi i runga i te paparanga whatunga o te tauira OSI, ka taea te whakahaere i te kawa TCP/IP; ka mahi te pana i runga i te paparanga whakawhiti i runga i te wāhitau MAC.
4. Mai i te tirohanga wehewehe, ka taea e te pouara te wehewehe i te rohe pāhoho, ā, ka taea anake e te pana te wehewehe i te rohe taupatupatu.
5. Mai i te tirohanga o te rohe tono, ko ngā pouara te nuinga e whakamahia ana hei hono i ngā LAN me ngā whatunga o waho, ā, ko ngā pana te nuinga e whakamahia ana mō te tuku raraunga i roto i ngā LAN.
6. Mai i te tirohanga atanga, e toru ngā atanga pouara: te tauranga AUI, te tauranga RJ-45, te tauranga SC, he maha ngā atanga pana, pērā i te tauranga Papatohu, te atanga MGMT, te tauranga RJ45, te atanga muka whatu, te atanga auc, te atanga vty me te Atanga vlanif, me ētahi atu.
