Uthungelwano lweNdawo yeNgingqi (LAN)
Ibhekisa kwiqela lekhompyuter elenziwe ziikhompyuter ezininzi ezidityaniswe kwindawo ethile. Ngokuqhelekileyo, iphakathi kwamawaka ambalwa eemitha ububanzi. I-LAN inokuqonda ulawulo lwefayile, ukwabelana ngesoftware, ukuprinta
Iimpawu ziquka ukwabelana ngomatshini, ukucwangcisa ngaphakathi kwamaqela omsebenzi, i-imeyile kunye neenkonzo zonxibelelwano zefeksi, kunye nokunye. Inethiwekhi yendawo yendawo ivaliwe kwaye inokuqulunqwa ngeekhompyutha ezimbini kwiofisi.
Inokubandakanya amawaka eekhompyuter ngaphakathi kwenkampani.
Uthungelwano lweNdawo eBanzi (WAN)
Yingqokelela yothungelwano lwekhompyuter oluthatha indawo enkulu, yengingqi. Ngokuqhelekileyo kuwo wonke amaphondo, izixeko, okanye ilizwe. Inethiwekhi yendawo ebanzi ibandakanya ii-subnets ezinobukhulu obahlukeneyo. Iisubnet zinako
Ingaba yinethiwekhi yendawo yendawo okanye inethiwekhi encinci yendawo ebanzi.
Umahluko phakathi kwenethiwekhi yendawo yendawo kunye nenethiwekhi yendawo ebanzi
Inethiwekhi yendawo yendawo ingaphakathi kwendawo ethile, ngelixa inethiwekhi yendawo ebanzi ithatha indawo enkulu. Ngoko ke ungayichaza njani le ndawo? Umzekelo, i-ofisi eyintloko yenkampani enkulu iseBeijing.
Beijing, kwaye amasebe asasazeke kulo lonke ilizwe. Ukuba inkampani idibanisa onke amasebe kunye ngenethiwekhi, ngoko isebe linethiwekhi yendawo yendawo, kunye nekomkhulu lonke.
Inethiwekhi yenkampani yinethiwekhi yendawo ebanzi.
Yintoni umahluko phakathi kwezibuko le-WAN kunye ne-LAN port ye-router?
I-router ye-broadband yanamhlanje ngokwenene sisakhiwo esidityanisiweyo somzila + wokutshintsha. Sinokuyicinga njengezixhobo ezibini.
I-WAN: Isetyenziselwa ukudibanisa kwiidilesi ze-IP zangaphandle, ngokuqhelekileyo ibhekisela kwi-egress, kunye neepakethi zedatha ye-IP yangaphambili ukusuka kwi-interface ye-LAN yangaphakathi.
I-LAN: Isetyenziselwa ukuqhagamshela kwidilesi ye-IP yangaphakathi. Ngaphakathi kweLAN kukho iswitshi. Asikwazi ukuqhagamshela kwizibuko le-WAN kwaye sisebenzise iumzilanjengesiqhelotshintsha.
I-LAN engenazingcingo (WLAN)
I-WLAN isebenzisa amaza e-electromagnetic ukuthumela nokufumana idatha emoyeni ngaphandle kwesidingo semidiya yentambo. Izinga lokudluliswa kwedatha ye-WLAN ngoku inokufikelela kwi-11Mbps, kwaye umgama wothumelo ngu
Imalunga nama-20km kude. Njengenye indlela okanye ukwandiswa kothungelwano lweentambo zemveli, i-LAN engenazingcingo ikhulula abantu kwiidesika zabo kwaye ibavumele ukuba basebenze nangaliphi na ixesha.
Ukufikelela kulwazi naphina kuphucula ukusebenza kwe-ofisi yabasebenzi.
I-WLAN inxibelelana kusetyenziswa ibhendi yosasazo yerediyo ye-ISM (yeShishini, iNzululwazi, yezoNyango). Umgangatho we-802.11a weWLAN usebenzisa ibhendi ye-5 GHz kwaye ixhasa kakhulu
Isantya esiphezulu yi-54 Mbps, ngelixa imigangatho ye-802.11b kunye ne-802.11g isebenzisa ibhendi ye-2.4 GHz kunye nesantya senkxaso ukuya kwi-11 Mbps kunye ne-54 Mbps ngokulandelanayo.
Ke yintoni i-WIFI esihlala siyisebenzisa ukufikelela kwi-Intanethi?
I-WIFI yiprothokholi yokuphumeza inethiwekhi engenazingcingo (eneneni iprotocol yokuxhawula izandla), kwaye i-WIFI ngumgangatho weWLAN. Inethiwekhi ye-WIFI isebenza kwi-2.4G okanye i-5G band frequency. Okunye
I-3G yangaphandle / 4G nayo inethiwekhi engenazintambo, kodwa iiprotocol zihluke kwaye ixabiso liphezulu kakhulu!
Uthungelwano lweNdawo yeNgingqi yeNgcono (VLAN)
I-LAN ebonakalayo (i-VLAN) ibhekisa kubuchwepheshe bothungelwano oluvumela iisayithi kuthungelwano ukuba zihlulwe ngokuguquguqukayo zibe subnets ezahlukeneyo ezinengqondo ngokweemfuno, kungakhathaliseki ukuba indawo yabo ebonakalayo.
Umzekelo, abasebenzisi kwimigangatho eyahlukeneyo okanye kumasebe ahlukeneyo banokujoyina i-LAN ezahlukeneyo ngokwenyani njengoko kufuneka: umgangatho wokuqala wahlulwe ube yinxalenye yenethiwekhi ye-10.221.1.0, kwaye umgangatho wesibini wahlulwe
10.221.2.0 icandelo lenethiwekhi, njl.
