Kombiyuta yako uye printer zvose zviri nodes network
Node ndeyese chigadzirwa chemuviri mukati memutambo wemamwe magadzirirwo anokwanisa kutumira, kugamuchira, uye / kana mberi mashoko. Iyo kombiyuta ndiyo inonyanya kukosha, uye inowanzonzi node yekombiyuta kana node ye internet .
Modems, switches, hubs, mabhiriji, mavharivha, uye makadhindiri zvakare node, sezvimwe zvimwe zviyero zvinobatana pamusoro pe WiFi kana Ethernet. Semuenzaniso, inetaneti inosangana nemakombiyuta matatu uye imwe printer, pamwe chete nemamwe mawena maviri asina tambo, ane node nhanhatu.
Nodes mukati memakombiyuta emakombiyuta inofanira kuva nehumwe hutano hwekufananidzira, kufanana neIndaneti kana MAC kero, kuitira kuti ionekwe nedzimwe nhare dzemagetsi. Node isina ruzivo urwu, kana imwe yakatorwa pasina, haisisiri mabasa seyode.
Chii chinonzi Network Network Node?
Node nodes ndiyo miviri inoumba musangano, saka pane kazhinji kacho mashomanana akasiyana.
A network network node inowanzoshandisa chero ipi zvayo inogamuchira uye inotaurira chimwe chinhu kuburikidza nemutambo, asi inogona kungogamuchira nekuchengetedza deta, kutumira mashoko kune imwe nzvimbo, kana kuumba uye kutumira dheta.
Semuenzaniso, kombiyuta yekombiyuta inogona kusimbisa mafaira ari paIndaneti kana kutumira email, asi inogonawo kuparadzira mavhidhiyo uye kutora mamwe mafaira. A network printer inogona kugamuchira zvinyorwa zvinyorwa kubva kune mamwe madivayiri pane network apo scanner inogona kutumira mifananidzo kumakombiyuta. A router inogadzirisa kuti chii chinopa ruzivo iyo majaira anokumbira mafaira akakodzwa mukati memutambo, asi anoshandiswawo kutumira zvikumbiro kune internet yevanhu vose.
Dzimwe Mhando dzeNodhi
Mune fiber-based based cable TV network, node ndiyo dzimba uye / kana mabhizimisi anowirirana kune rimwechete fiber optic receiver.
Chimwe chimiro chekodhi ndicho chigadziro chinopa hutano hwehutano hwebasa mukati memagetsi emagetsi, sechigaro chemasimiti chepamusoro (BSC) kana Gateway GPRS Support Node (GGSN). Mune mamwe mazwi, node yemasero ndiyo inopa software yekugadzirisa kumashure kwemajeri emagetsi, sezvakaita shanduro nemaina anoshandiswa kuparidzira zviratidzo kune zvese zviri mukati memasero emagetsi.
A supernode is node mukati pe peer-to-peer network iyo inoshanda kwete chete seyode yekare asi zvakare seyo proxy server uye chimbo chinotumira mashoko kune vamwe vashandisi mukati memutanhau weP2P. Nemhaka yeizvi, supernodes inoda mamwe CPU uye bandwidth pane nguva dzose dzinowanikwa.
Chii Chinonzi Kuguma-Node Dambudziko?
Pane izwi rinonzi "chirwere chekupedzisira" chinoreva kusachengetedzwa kwekuchengetedzwa kunouya nevashandisi vanobatanidza makombiyuta avo kana zvimwe zvigadzirwa kumatareti asina kunaka, kana mumuviri (sekushanda) kana kuburikidza negore (kubva kupi zvako), panguva imwe chete nguva inoshandisa chipimo ichocho kuita mabasa asina kuchengetedzwa.
Mimwe mienzaniso inosanganisira mushumiri wekupedzisira anotora basa ravo kumba kumba asi anotarisa email yavo pane imwe nzvimbo isina kuchengetedzwa yakafanana nechitoro chekofi, kana munhu anoshandisa kombiyuta yavo kana foni ku WiFi network yekambani.
Imwe yezvipingamupinyi zvakanyanya kune unyanzvi hwekubatanidza ndeye chigadzirwa chemunhu chakashandiswa uye chinoshandiswa pane iyo network. Dambudziko rakanaka zvakajeka: chigadzirwa ichi chinosanganisa zvingangove zvisina kuchengetedzwa netsika uye bhizinesi rebhizimisi iro rinogona kunge rine data yakangwara.
Imwe michina yekushandisa yomugumo inogona kunge iine malware- yakaratidzwa nezvinhu zvakadai se keyloggers kana mapurogiramu ekufambisa mafaira anobvisa ruzivo ruzivo kana kutora malware kune network yega yega kana hutano hwave hwakagadzirwa.
Kune nzira dzakawanda dzekubatsira kudzivisa dambudziko iri, kubva kuVPN uye mbiri-chechokwadi kuvheekable client software iyo inogona kungoshandisa mamwe mapurogiramu ekusvika kure .
Zvisinei, imwe nzira ndeyekudzidzisa vashandisi nzira yekuchengetedza zvakanaka chigadzirwa chavo. Mapepa ega ega anogona kushandisa chirongwa chinonzi antivirus kuchengetedza mafaira avo akadzivirirwa kubva kune malware, uye mafoni angashandisa shanduro yeAntimalware yakafanana kuti inobata mavirisi nezvimwe zvinopisa vasati vakuvadza.
Zvimwe Node Zvinoreva
Node ishokowo rinoshandiswa kurondedzera kombiyuta faira apo inotaura nezvemuti wekugadzirisa demo. Zvakafanana nemuti chaiwo apo matavi anobata mashizha awo, mahwindo mukati mekugadzirwa kwe data vanobata mafaira avo. Mafaira angadaidzwa mavara kana mashizha mapeji .
Izwi rokuti "node" rinoshandiswawo ne node.js, iyo inonzi JavaScript nguva yekushandiswa yakashandiswa pakushandisa server-side JavaScript code. I "js" mu node.js haina kureva kuwedzera kweJS yefaira inoshandiswa neJavaScript mafaira asi zvinongova zita rekushandisa.
