Ikhompyutheni yakho kanye nephrinta kokubili kokungena kwenethiwekhi
I-node yinoma iyiphi idivayisi ngokomzimba ngaphakathi kwenethiwekhi yamanye amadivayisi akwazi ukuthumela, ukuthola, kanye / noma ukuthumela ulwazi. Ikhompiyutha yiyona node ejwayelekile kunazo zonke, futhi ivame ukubizwa ngokuthi i- node yekhompyutha noma i- intanethi ye-intanethi .
Amamodeli, ukushintshwa, ama-hubs, amabhuloho, amaseva, namaphrinta nazo zingamakhodi, njengamanye amadivayisi axhuma nge-WiFi noma i-Ethernet. Isibonelo, inethiwekhi exhuma amakhomphyutha amathathu kanye nephrinta eyodwa, kanye namanye amadivaysi amabili angenawaya, inezakhi eziyisithupha eziphelele.
Amakhadi ngaphakathi kwenethiwekhi yekhompyutha kumele abe nenhlobo ethile yokukhomba, njengekheli le- IP noma ikheli le-MAC, ukuze lihlonishwe amanye amadivaysi enethiwekhi. I-node ngaphandle kwalolu lwazi, noma eyodwa ethathwe ngaphandle kokuxhumeka ku-intanethi, ayisekho imisebenzi njenge-node.
Yenzani I-Node Network?
Ama-node enethiwekhi yizingcezu zomzimba ezakha inethiwekhi, ngakho-ke zivame ukuba nezinhlobo ezimbalwa ezihlukene.
I-node yenethiwekhi ivame noma yimuphi umshini owamukela kokubili bese ekhuluma okuthile ngokusebenzisa inethiwekhi, kodwa esikhundleni salokho angathola futhi agcine idatha, adlulisele ulwazi kwenye indawo, noma adale futhi athumele idatha.
Isibonelo, i-node yekhompyutha ingahle ivuselele amafayela ku-intanethi noma ithumele i-imeyili, kodwa ingabuye isakaza amavidiyo futhi ilande amanye amafayela. Iphrinta yenethiwekhi ingathola izicelo zokuphrinta kusuka kwamanye amadivayisi kwinethiwekhi ngenkathi isithwebuli singathumela izithombe emuva kwikhompyutha. I- router inquma ukuthi iyiphi idatha enikeziwe ukuthi yimaphi amadivayisi acela ukulandwa kwefayela ngaphakathi kwenethiwekhi, kodwa futhi asetshenziselwa ukuthumela izicelo ku-inthanethi yomphakathi.
Ezinye izinhlobo zamaNode
Enethiwekhi ye-cable ye-cable ye-fiber, ama-node yiwona amakhaya kanye / noma amabhizinisi axhunyiwe kumceiver of fiber optic ofanayo.
Esinye isibonelo se-node yidivayisi ehlinzeka ngenethiwekhi yenethiwekhi ehlakaniphile ngaphakathi kwenethiwekhi yeselula, njengesilawuli sesiteshi sesisekelo (BSC) noma i-Gateway GPRS Support Node (GGSN). Ngamanye amazwi, i-node yeselula yilokho enikeza izilawuli zesofthiwe ngemuva kwemishini yeselula, njenge-sakhiwo ngama-antenna asetshenziselwa ukudlulisela izimpawu kuwo wonke amadivayisi ngaphakathi kwenethiwekhi yeselula.
I-supernode iyi-node ngaphakathi kwenethiwekhi yontanga ukuya enkundleni engasebenzi nje kuphela njenge-node ejwayelekile kepha futhi njengeseva ye-proxy kanye nedivayisi ehambisa ulwazi kwabanye abasebenzisi ngaphakathi kwenethiwekhi ye-P2P. Ngenxa yalokhu, ama-supernode adinga i- CPU eyengeziwe kanye nomkhawulokudonsa kunama-node avamile.
Iyini Inkinga Yokuphela Kwenkinga?
Kukhona igama elibizwa ngokuthi "inkinga yokugcina i-node" ebhekisela engozini yokuphepha efika nabasebenzisi abaxhuma amakhompyutha abo noma amanye amadivaysi kwinethiwekhi ebucayi, mhlawumbe ngokomzimba (njengokusebenza) noma ngefu (noma ikuphi), ngesikhathi esifanayo isikhathi usebenzisa lelo foni efanayo ukwenza imisebenzi engaqinisekisiwe.
Ezinye izibonelo zibandakanya umsebenzisi wokugcina othatha umsebenzi wabo ekhaya ekhaya kodwa ahlola i-imeyili yabo kunethiwekhi engaphephile njengositolo sekhofi, noma umsebenzisi oxhuma ikhompuyutha yakhe noma ifoni kwinethiwekhi ye-WiFi yenkampani.
Enye yezingozi ezinkulu kunethiwekhi yezinkampani idivayisi yomuntu siqu esetshenzisiwe bese isetshenziselwa leyo nethiwekhi. Inkinga ibonakala kahle: idivaysi ixuba inethiwekhi engavikelekile futhi inethiwekhi yebhizinisi cishe iqukethe idatha ebucayi.
Idivaysi yomsebenzisi wokugcina kungenzeka ibe yi- malware- iboniswe ngezinto ezinjenge-keyloggers noma izinhlelo zokudlulisa ifayela ezikhipha ulwazi olubucayi noma ukuhambisa i-malware kunethiwekhi yangasese uma uxhumano lwenziwe.
Kunezindlela eziningi zokusiza ukugwema le nkinga, kusuka ku- VPN kanye nokuqinisekiswa kwezinto ezimbili kwi-software ekhethiwe yeklayenti ye- bootable engasebenzisa kuphela izinhlelo ezithile zokufinyelela ezikude .
Kodwa-ke, enye indlela iwukuba nje ufundise abasebenzisi indlela yokuvikela kahle idivayisi yabo. I-laptops yomuntu siqu ingasebenzisa uhlelo lwe-antivirus ukugcina amafayela abo avikelwe kusuka ku-malware, futhi ama-smartphone angasebenzisa uhlelo lokusebenza olufanayo lwe-antimalware ukuze abambe amagciwane nezinye izinsongo ngaphambi kokuba abangele ukulimala.
Amanye ama-Node Meanings
I-Node iyigama elisetshenziselwa ukuchaza ifayela lekhompyutha lapho libhekisela kwisakhiwo sedatha yesigodi. Njengomuthi wangempela lapho amagatsha anamaqabunga awo, amafolda angaphakathi kwesakhiwo sedatha abamba amafayela abo. Amafayela angase abizwe ngokuthi amahlamvu noma amaqabunga amaqabunga .
Igama elithi "node" lisetshenziselwa node.js, okuyinto imodi yokugijima ye-JavaScript esetshenziselwa ukwenza i-server-side JavaScript ikhodi. I "js" ku-node.js ayibheki isandiso sefayili se- JS esetshenziselwa amafayela we-JavaScript kodwa esikhundleni salokho kuphela igama lethuluzi.
