ʻO kāu kamepiula a me ka mea paʻi palapalaʻo nā pūnaewele pūnaewele
ʻO kahi kīpili kekahi mea kino i loko o kahi pūnaewele o nā mea'ē aʻe e hiki ke hoʻouna, loaʻa, a / a ma waho paha kaʻike. ʻO ka computer kaʻoi aku o ke kikowaena maʻamau, a ua kapaʻiaʻo ia ka'īpona rorohiko a iʻole ka pūnaewele pūnaewele .
ʻO nā modem, nā hoʻololi, nā hui, nā alahaka, nā kikowaena, a me nā mea paʻi pū he nodes hoʻi, e like me nā mea'ē aʻe e pili ana i ka WiFi a iʻole ka Ethernet. Eia kekahi laʻana,ʻo kahi pūnaewele e pili ana iʻekolu mau lekapihi a me kahi mea paʻi pū, meʻelua mauʻaila'ēʻole,ʻeono mau helu helu.
Pono nāʻona i loko o kahi pūnaeweleʻike i kahi o kaʻikeʻana, e like me kahi IP IP a iʻole ka helu MAC, no kaʻikeʻia e nā mea'ē aʻe. ʻO kahi kīnā me kaʻole o kēiaʻike, a iʻole kahi i laweʻia offline,ʻaʻole e hana hou e like me ka'īpuka.
He aha ka hanaʻana o ka Node Network?
ʻO nā pūnaewele pūnaewele ka'āpana kino e hana ai i kahi mea kikowaena, no laila, he mauʻano likeʻole nāʻano likeʻole.
ʻO ka'ōpili pūnaewele kekahi mea i loaʻa a loaʻa a loaʻa kekahi mea ma o ka pūnaewele, akā paha e loaʻa wale a mālama i nāʻikepili, e pākaho i kaʻike ma kahi'ē aʻe, a iʻole e hana a hoʻouna i nāʻikepili.
Eia kekahi laʻana, hiki ke hoʻopili i nā leka uila ma ke kelepona a hoʻouna aku paha i kahi leka uila, akā hiki iā ia ke kahawai i nā wikiō a me nā kiʻi'ē aʻe. Hiki i kekahi mea paʻi kiʻi ke lawe i nā noi lolo mai nā mea'ē aʻe ma ka pūnaewele kahi e hiki ai i ka scanner ke hoʻokuʻu i nā kiʻi i ka kamepiula. Hoʻoholo ka mea hoʻopili i kaʻikepili i hāʻawiʻia i kēlā me kēia polokalamu e noi nei i nā waihona pūnaewele i loko o kahi pūnaewele, akā hoʻohanaʻia hoʻi e hoʻouna i nā noi i ka pūnaewele puni honua.
Nā Kūlana'ē aʻe o Nodes
Ma kahi pūnaewele kelepa o ke kelepa uila,ʻo nāʻona ka hale a me nāʻoihana e pili ana i ka mea koho like fiber optic.
ʻO kekahi hiʻohiʻona o ka'ōpili kekahi mea e hāʻawi ana i ka lawelawe pūnaewele akamai i loko o kahi pūnaewele pūnaewele, e like me kahi mea hoʻonohonoho hoʻonohonoho waihona (BSC) a iʻole Gateway GPRS Support Node (GGSN). I kekahi'ōlelo'ē aʻe,ʻo ka pūnana pūnaewele ka mea e hāʻawi ai i nā mana pūnaewele ma hope o nā mea hana pūnaewele, e like me keʻano me nā antenia i hoʻohanaʻia no ka laweʻana i nā hōʻailona i nā mea a pau i loko o ka pūnaewele pūnaewele.
ʻO kahi kikowaena he kōpuku i loko o kahi pūnaewele hoa-a-hoa e hanaʻaʻole wale ma keʻano he'ōpena maʻamau akā, e like me ke kikowaena kūpaʻa a me ka mea e pili ana i nāʻike i nā mea hoʻohana'ē aʻe ma loko o ka pūnaewele P2P. Ma muli o kēia, makemake nā supernodes i ka CPU a me ka bandwidth ma mua o nā pūnana maʻamau.
He aha ka hopena hōʻahoʻae?
Aia kekahi manawa i kapaʻia "hopena hoʻopiʻi hopena" e pili ana i ka pilikia pale e hiki mai me nā mea hoʻohana e hoʻohui pū ana i kā lākou mau kamepiula a iʻole nā mea'ē aʻe i kahi pūnaewele koʻikoʻi, ma ke kino (e like me ka hana) a ma o ke ao paha (mai kahi'ē aʻe) manawa e hoʻohana ana i kēlāʻano hana e hana i nā hana unsecured.
ʻO kekahi mau hiʻohiʻona e komo pū ana me kahi mea hoʻohana i lawe i kā lākou hana laptop i ka home a laila e leka i kā lākou leka uila ma kahi lakaʻole e like me ka hale kūʻai kope, aiʻole kekahi mea hoʻohana i kā lākou kamepiula pilikino a iʻole kelepona i ka pūnaewele WiFi.
ʻO kekahi o ka pilikia nui i kahi pūnaeweleʻoihana he polokalamu pilikino i hoʻohanaʻia a hoʻohanaʻia ma ia pūnaewele. ʻO ka pilikia ua maopopo loa: ke hui pū nei ka puna i kahi pūnaewele paʻaʻole a me ka laikiniʻoi aku i loaʻa nāʻikeʻike maʻalahi.
ʻO ka mea hoʻohana o ka mea hoʻohana hope paha he polokalamu hoʻopilikia-i hoʻokūʻia me nā mea like keyloggers aiʻole nā papa hana hoʻoiliʻana e hoʻokaʻawale i nāʻike maʻalahi a hoʻololi paha i nā pūnaewele i ka pūnaewele pūnaewele i ka manawa i hoʻokumuʻia ai ka pilina.
Nui nāʻano e kōkua ai i ke kāohiʻana i kēia pilikia, mai ka VPNs a me ka hōʻoia ponoʻelua-helu i kahi polokalamu polokalamu kūikawā kūikawā hiki ke hoʻohana wale i kekahi mau polokalamu i ka mamao .
Eia naʻe,ʻo kekahi kumu'ē aʻe,ʻo ia wale nō ka hoʻonaʻauaoʻana i nā mea hoʻohana i ke ala e hoʻopaʻa pono ai i kā lākou mea hana. Hiki i nā kamepiula laulā ke hoʻohana i ka polokalamu kamepiula e mālama i kā lākou mau kōnae i kāohiʻia mai nā polokalamu kamepiula, a hiki i nā smartphones ke hoʻohana i kekahi polokalamu antimalware like e hopu ai i nā meaʻino a me nā mea'ē aʻe ma mua o ka hanaʻana i kekahi pōʻino.
Nāʻona Node'ē aʻe
Node ka'ōlelo i hoʻohanaʻia no ka weheweheʻana i kahi waihona kamepiula i ka manawa e pili ana i ka hoʻomohalaʻikepili lāʻau. Ua like me ka lāʻau maoli i kahi o nā lālā i paʻa ai i nā lā'ī, nā waihona i loko o kahi o kaʻikepili paʻa i kā lākou mau waihona iho. Hiki i nāʻili ke kapa 'ia he lālā lau aiʻole rau .
Hoʻomoe pūʻia ka hua'ōlelo "node" me node.js, he manawa wikiwiki JavaScript e hoʻohanaʻia no ka hoʻokōʻana i kaʻaoʻao o kaʻaoʻao kikowaena JavaScript. 'Aʻole e pili ka "js" ma node.js i ka hoʻolako pūnaewele JS i hoʻohana' ia me nā JavaScript JavaScript akā 'o ia ka inoa o ka mea hana.
