He aha ka Difference?
Hoʻokahiʻaoʻao e hoʻokaʻawale i nāʻanoʻokoʻa o nāʻokoʻa pili kelepona ma muli o ka nui a me ke anana. No nāʻike o ka mōʻaukala, ua pili kaʻoihana pūnaewele i kaʻaneʻane o kēlā me kēiaʻano o ka hoʻolālā e like me kekahiʻano o ka pūnaewele . ʻO nāʻano maʻamau o nā pūnaewele kaiaulu:
- LAN - Local Network Network
- WAN - Wide Area Network
- WLAN - Local Local Network
- ʻO MAN - Metropolitan Area Network
- SAN - Pūnaewele Pūnaewele, Pūnaeho Pūnaewele Pūnaewele, Pūnaewele Kahua Pūnaewele, a i kekahi manawa paha ma kahi Pūnaewele Pūnaewele
- CAN - Ka 'Āpana Campus, Manawaena Pūnaewele Pūnaewele, a i kekahi manawa Cluster Area Network
- PAN - Personal Network Network
ʻO LAN a me WAN nā inoaʻelua aʻike nui loaʻia o nā'enele o ka'āpana, kahi'ē aʻe o nā mea'ē aʻe me ka hoʻonuiʻana i keʻenehana
Eʻike i nāʻano likeʻole o kaʻikepili pūnaewele (e like me ka pahi, ke kani a me ka hōkū). (E nānā i - Hoʻomākaukau i ka Pūnaewele Pūnaewele .)
LAN: Local Local Network
Kūleʻaʻo LAN i nā polokalamu kelepona i kahi mamao lōʻihi. ʻO kahi hale o ke keʻena i hoʻopaʻaʻia, kahi kula, a home paha he mau LAN hoʻokahi wale nō, akā i kekahi manawa, aia kekahi hale i kahi mau LAN liʻiliʻi (paha hoʻokahi ma kahi lumi), a ma kekahi manawa he LAN e hele i kahi hui. Ma ka pūnaewele TCP / IP,ʻaʻohe manawa LAN i hoʻohana mauʻia e like me kahi subnet IP pono .
Ma waho aʻe o ka hanaʻana i kahi manawa liʻiliʻi, aia kekahi mau LANs i ka mana, ka hoʻomaluʻia, a me ka mālamaʻia e kahi mea hoʻokahi a hui paha. Hoʻoikaika lākou e hoʻohana i kekahi mauʻenehana pili pūnaewele,ʻo Ethernet a me Token Ring .
WAN: Wide Regional Network
E like me keʻano o ka hua'ōlelo, hiki ke WAN i kahi mamao ākea nui. ʻO ka Pūnaewele ka WAN nui nui loa, a puni ka Honua.
ʻO kahi WAN kahi hōʻiliʻili'āina o ka LAN. ʻO kahi mea kikowaena i kapaʻia he alalai e hoʻohui i LANs i kahi WAN. Ma ka pūnaewele IP, e hoʻomau ka mea hoʻopuka i kahi helu LAN a me kahi helu WAN.
Heʻokoʻa ka WAN i kahi LAN ma nāʻanoʻano nui. ʻO ka hapa nui o nā mea likeʻole (e like me ka Pūnaewele)ʻaʻole lākou i mālamaʻia e kekahi hui, akā, e noho nei ma lalo o ka hui likeʻole a iʻole i ka hoʻopiliʻiaʻana o ka pono a me ka mana. Nāna e hoʻohana i kaʻenehana like me ATM , Frame Relay a X.25 no ka hoʻohuiʻana ma kahi lōʻihi.
LAN, WAN a me Kāleka Home
Hiki i nā hale noho ke hoʻohana i kahi LAN a hoʻohui i ka WAN Pūnaewele ma o ka Pūnaewele Pūnaewele (ISP) me ka hoʻohanaʻana i kahi modem weluwelu . Hoʻokumu ka ISP i kahi IP IP WAN i ka modem, a ua hoʻohanaʻia nā papahana a pau e ka mea hoʻohana i ka inoa LAN (kahi i kapaʻiaʻo kahi pilikino IP). Hiki i nā papahana a pau ma ka home LAN ke kamaʻilio maʻamau me kekahi i kekahi akā pono e hele ma waena o ka pūnaewele kikowaena pūnaewele ,ʻo ia hoʻi he mea hiki kelepona mamao , hiki i ka ISP.
Nā Kūlana'ē aʻe o nā Pūnaewele Pūnaewele
ʻOiaiʻo LAN a me WAN ma kahi mamao loa i nāʻano kikowaena i haʻiʻia, hiki iāʻoe keʻike i nā kuhikuhi i kēia mau mea'ē aʻe:
- Ka Paena Pūnaewele Lālewa Alaʻole -ʻO kahi LAN e pili ana i kaʻenehanaʻenehana uila Wi-Fi
- Pūnaewele Pūnaewele -ʻO kahi kikowaena eʻike ana i kahi papaʻano nui ma mua o ka LAN akā he mea liʻiliʻi hoʻi ma kahi WAN, e like me ke kūlanakauhale. Hoʻohana a lawelaweʻia kekahi MAN e kahi hui likeʻole i ke aupuni a iʻole i ka hui nui.
- Pūnaewele Pūnaewele -ʻO kahi kikowaena eʻike ana i nā LAN nui akā he mea liʻiliʻi aku i kahi MAN, e like me ke kulanui a me ka pā kula kūloko.
- Kuhi Pūnaewele - Hoʻokomo i nā pūnaewele i nā polokalamu keleponaʻikepili ma o kaʻenehana like me ka Fiber Channel .
- Pūnaewele Pūnaewele (i kapa pūʻiaʻo Cluster Area Network) - Nā pūnaehana kiʻekiʻe kiʻekiʻe me nāʻawelike hikiwawe i ka hoʻolālā o ka hui.
