Ma ka wehewehe ʻana, a ʻupenao nā kamepiula a i ʻole pūnaewele kamepiula He set o lako paʻa a lako polokalamu (nā hāmeʻa a me nā papahana) pili i kekahi i kekahi ma o nā mea kūpona no ka hoʻouna ʻana a me ka loaʻa ʻana o ka ʻike, i mea e kaʻana like ai i ka ʻikepili, hoʻokele i nā kumuwaiwai a hāʻawi i nā ʻano lawelawe like ʻole.

Hana kēia mau pūnaewele e like me kekahi ʻano o ke kamaʻilio paʻa: ma o ka launa pū a me ka pānaʻi pānaʻi ʻana o nā mea hoʻouna a me nā mea loaʻa ma o ke kahe kino a me ka hoʻohana ʻana i kahi code maʻamau. E pili ka hana o ka pūnaewele i ka hoʻonohonoho ʻana o kēia mau mea, no ka laʻana, ka wikiwiki o ka lawe ʻana o ka ʻikepili..

ʻO ka pūnaewele nui loa i hana ʻia e ke kanaka i kēia lā ʻo ka Pūnaewele: kahi pūnaewele nui o miliona o nā kamepiula i hoʻopili ʻia i nā wahi like ʻole o ka honua, kaʻana like ʻana i ka ʻike ma ka pālākiō a ʻae ʻia e hana i nā kaʻina hana a me nā lawelawe.

Nā ʻano pūnaewele

Nui nā hoʻonohonoho ʻana o nā pūnaewele kamepiula, kahi e kamaʻilio ai i nā ʻaoʻao like ʻole o kā lākou hana: kā lākou ʻano pilina, kā lākou pilina hana, kā lākou topology kino, kā lākou kekelē o ka diffusion, hōʻoia a i ʻole ko lākou ʻikepili kuhikuhi, akā ʻo ka mea ʻike ʻia paha ka hoʻokaʻawale e like me kona laulā.

No laila, hiki iā mākou ke kamaʻilio e pili ana i ʻekolu ʻano o ka pūnaewele, ʻo ka mea nui:

• Nā pūnaewele LAN (Pūnaewele ʻĀpana Kūloko). Aia ka inoa i ka inoa o ka acronym ma ka ʻōlelo Pelekania no ka Local Area Network, a ʻo ia nā mea i kaupalena ʻia i kāna wahi i wehewehe ʻia i nā ʻāpana liʻiliʻi, e like me kahi keʻena, kahi keʻena, kahi mokulele, a me ka hale like. ʻO ka nele i ka lehulehu o ka pilina, mālama ʻia lākou ma ke ʻano he wahi kikowaena hoʻokahi, ʻoiai ka hiki iā lākou ke lawelawe i nā mea hoʻohana he nui i ka manawa like.
• Nā pūnaewele MAN (Pūnaewele Area Metropolitan). Aia ka inoa o ka inoa inoa i ka ʻōlelo haole ma ka ʻōlelo Pelekania no ka Metropolitan Area Network, ʻoiai he kikowaena wikiwiki wikiwiki ia e hāʻawi ana i ka uhi ʻana i kahi wahi ʻāina ʻoi aku ka nui ma mua o kahi LAN (ʻoiaʻiʻo he nui kekahi o lākou), akā paʻa mau a wehewehe ʻia, ma ke ʻano he hapa o ke kulanakauhale.
• Nā pūnaewele Wan (Pūnaewele Area ākea). Aia ka inoa i ka inoa o ka acronym ma ka ʻōlelo Pelekania no Wide Area Network, a ʻo kēia manawa e pili ana i nā pūnaewele laulā a me ka wikiwiki, e hoʻohana ana i nā satellite, cabling, microwaves a me nā ʻenehana hou e uhi ai i kahi ʻāpana ʻāina nui. ʻO ka Pūnaewele, me ke kānalua ʻole, he WAN o nā kūlike honua.

Pākuʻi pūnaewele

ʻO nā kamepiula e hana ana i nā pūnaewele e kamaʻilio pū kekahi me kekahi e ʻōlelo ana i ka "ʻōlelo" like, i kāhea ʻia kikowaena pūnaewele. Nui a hewahewa paha nā kaʻina hana, nā kūlana kamaʻilio a me nā manaʻo o ka hana pūnaewele nui, akā ʻo nā mea maʻamau he ʻeluaA I OLE (Hoʻohui ʻōnaehana Open: wehe i ka pilina o nā ʻōnaehana) aTCP / IP (Pākuʻi halihali a me ka pale pūnaewele).

ʻOkoʻa nā kuʻina ʻelua i ka hoʻolālā ʻana i ka kamaʻilio i nā ʻano like ʻole. ʻOiai ʻehiku mau OSI i wehewehe ʻia o nā papa o ke kamaʻilio a me nā hana kikoʻī, ʻehā wale nō ʻo TCP / IP akā kūkulu ʻia ma ke kumu o kahi ʻano pālua. ʻO ka hope ka mea maʻamau a hoʻohana nui ʻia a puni ka honua.

Nā laʻana o nā pūnaewele LAN

1. He pūnaewele pūnaewele. E like me ka uea ʻole (Wifi) i hiki i kekahi ke hoʻouka ma ka home e lawelawe i nā kamepiula ʻelua a me nā kelepona paʻalima. ʻAʻole paʻakikī ka laulā i nā palena o ka ʻoihana.
2. Kuhi pūnaewele. ʻO nā lālā liʻiliʻi o kahi ʻoihana a hale kūʻai paha i kā lākou pūnaewele ponoʻī, e hoʻolako i ka pili pūnaewele i kā lākou kamepiula a, pinepine, i nā mea kūʻai aku.
3. Kuhi pūnaewele waena o kahi keʻena. I nā keʻena, hoʻokomo ʻia kahi pūnaewele kūloko (intranet) e kamaʻilio pinepine i nā kamepiula o nā limahana a pau, ʻae iā lākou e komo pū i nā peripherals (e like me ka mīkini paʻi like) a kaʻana like i nā pā hana a i ʻole nā ​​mea hoihoi like.
4. Kahi pūnaewele lehulehu i kahi huinahā. I nā kūlanakauhale he nui ua hoʻokō ʻia ka papahana pūnaewele lehulehu a manuahi hoʻi, ma o nā kiko pilina uea ʻole me kahi pae i ʻoi aku ma mua o kekahi mau mika i kahi lekiō.
5. ʻO kahi pūnaewele serial i kahi lumi. ʻO nā hale kūʻai pūnaewele a i ʻole nā ​​keʻena kelepona kahi ʻoihana i loaʻa nui ka boom me ka komo ʻana o ka Pūnaewele ma mua o ka hōʻea ʻana o ka Waihona uila. Loaʻa iā lākou i kahi mau kamepiula me kahi pūnaewele pūnaewele i hiki ke hoʻohana ʻia no ka lehulehu., akā kau ʻia i loko o kahi pūnaewele i kū ka mana i ka kamepiula o ka luna o nā wahi.

Nā laʻana o nā pūnaewele MAN

1. ʻO kahi pūnaewele waena waena. Pono nā ʻoihana aupuni he nui i ka hana like a i ʻole kaʻana like i ka nui o ka ʻike Hoʻohui ʻia lākou ma o ka pūnaewele fiber optic e ʻae iā lākou e noho ma kēlā ʻaoʻao o ke kūlanakauhale a lilo i ka launa ʻole.
2. ʻO kahi pūnaewele ma waena o nā lālā. Pili nā hale kūʻai he nui a me nā ʻoihana i ke kūlanakauhale hoʻokahi, e ʻae nei i kahi mea hoʻohana e ʻimi i kahi huahana i ka lālā kokoke loa, a inā ʻaʻole loaʻa, Hiki iā lākou ke noi iā ia ma kahi wahi ʻē aʻe a i ʻole, ma ka hihia ʻoi loa, kuhikuhi i ka mea kūʻai aku i ka puke ma kekahi lālā ʻē aʻe.
3. He pūnaewele o kahi ISP kūloko. Kapa ʻia ʻo ISP (Mea hoʻolako pūnaewele) i nā ʻoihana e kūʻai aku nei i ka poʻe ma ka pūnaewele. Hana pololei lākou ia ma o nā pūnaewele MAN āpau, e mālama pono kēlā me kēia i nā kumuwaiwai o ke kūlanakauhale a i ʻole kahi wahi. i nā mea kūʻai aku ʻē e noi ana iā ia, ʻo ia hoʻi, i kēlā me kēia LAN.
4. Kahi pūnaewele ma kahi pā kula. Kapa ʻia ʻo CAN (Pūnaewele Area Campus), he MAN maoli lākou i hoʻololi ʻia i nā hale like ʻole āpau i kūkulu ʻia i kūlanakauhale kūlanakauhale, a hiki iā lākou ke hoʻokaʻawale kūpono ʻia i kekahi i kekahi e kahi mamao loa.
5. ʻO kahi pūnaewele aupuni aupuni. Māhele pinepine ʻia ka ʻikepili o ke kaona a me ka mayoralty paha i kahi pūnaewele e pili wale ana i ka poʻe e noho ana i loko, no ka mea he kamaʻāina kā nā kamaʻāina ʻē aʻe. No laila, hiki ke hoʻokō pono ʻia ka uku ʻana i nā ʻauhau aupuni a i ʻole nā ​​kaʻina hana bureaucratic..

Nā laʻana o nā pūnaewele WAN

1. Pūnaewele. ʻO ka laʻana ʻoi loa o kahi WAN i loaʻa ʻo ia ka Pūnaewele, hiki ke kamaʻilio i nā ʻano ʻenehana like ʻole ma kahi mamao loa, mai kekahi ʻaoʻao o ka honua i kekahi. He pūnaewele nui ʻo ia i hoʻohālikelike ʻia i ka moana, kahi ala kiʻekiʻe, a i ʻole ke ao holoʻokoʻa..
2. ʻO kahi pūnaewele kikowaena ʻāina. Mālama ʻia nā lālā panakō ma kahi ʻāina ma o ka pūnaewele nui a pili pū me nā panakō ʻē aʻe a me nā panakō ʻē aʻe. ʻO kēlā me kēia pūnaewele he WAN e ʻae i kahi mea hoʻohana e huki kālā ma kahi ATM ma kēlā ʻaoʻao o ka ʻāina, a i ʻole ma kahi ʻāina ʻē aʻe..
3. Nā pūnaewele ʻoihana transnational. ʻO nā franchise ʻoihana nui i loaʻa i nā ʻāina like ʻole o ka honua, mālama i kā lākou mau limahana ma o kahi WAN kū hoʻokahi o ka ʻoihana, i hiki ai iā lākou ke hoʻololi i ka ʻike a hoʻomau i ka pili mau ʻana ʻoiai ma nā ʻāina like ʻole.
4. Pūnaewele ukali pūʻali koa. ʻO nā pūnaewele like ʻole o ka pale ʻana a me ka pūʻali koa e pili ana i nā satellite, nā moku, nā mokulele a me nā kaʻa ʻē aʻe i hoʻopuehu ʻia a puni ka honua. he ākea ākea lākou a nui loa i ka laulā, no laila hiki ke ʻano WAN wale nō.
5. Uku i nā pūnaewele TV. Kelepona a kīwī kīwī a me nā lawelawe leʻaleʻa a me ka ʻike e pili ana i nā ʻenehana hou, hoʻohana pono i kahi pūnaewele WAN e hoʻohui i kā lākou poʻe kau inoa ma nā ʻāina like ʻole i nā wahi like ʻole o ka ʻāina.
