Inethiwekhi yendawo yendawo (LAN)
Kubhekiselwa eqenjini lekhompuyutha elakhiwe amakhompyutha amaningi axhumene endaweni ethile.Ngokuvamile, ingaphakathi kwamamitha ayizinkulungwane ezimbalwa ububanzi.I-LAN ingabona ukuphathwa kwefayela, ukwabelana kwesofthiwe yohlelo lokusebenza, ukuphrinta
Izici zifaka ukwabelana komshini, ukuhlela ngaphakathi kwamaqembu omsebenzi, i-imeyili nezinsizakalo zokuxhumana zefeksi, nokuningi.Inethiwekhi yendawo ivaliwe futhi ingakhiwa amakhompyutha amabili ehhovisi.
Ingaqukatha izinkulungwane zamakhompyutha ngaphakathi kwenkampani.
Inethiwekhi yendawo ebanzi (WAN)
Kuyiqoqo lamanethiwekhi ekhompyutha ahlanganisa indawo enkulu, yesifunda.Ngokuvamile kuzo zonke izifundazwe, amadolobha, noma ngisho nezwe.Inethiwekhi yendawo ebanzi ihlanganisa ama-subnet anosayizi abahlukene.Ama-subnet angakwazi
Kungaba inethiwekhi yendawo yendawo noma inethiwekhi encane yendawo ebanzi.
Umehluko phakathi kwenethiwekhi yendawo yendawo kanye nenethiwekhi yendawo ebanzi
Inethiwekhi yendawo yendawo ingaphakathi kwendawo ethile, kuyilapho inethiwekhi yendawo ebanzi ithatha indawo enkulu.Ngakho-ke ungayichaza kanjani le ndawo?Isibonelo, ihhovisi elikhulu lenkampani enkulu liseBeijing.
Beijing, namagatsha asabalale ezweni lonke.Uma inkampani ixhuma wonke amagatsha ndawonye ngenethiwekhi, khona-ke igatsha liyinethiwekhi yendawo yendawo, kanye nendlunkulu yonke.
Inethiwekhi yenkampani iyinethiwekhi yendawo ebanzi.
Uyini umehluko phakathi kwembobo ye-WAN nembobo ye-LAN yomzila?
Irutha ye-broadband yanamuhla empeleni iyisakhiwo esihlanganisiwe sokushintshwa komzila +.Singacabanga ngakho njengamadivaysi amabili.
I-WAN: Isetshenziselwa ukuxhuma kumakheli e-IP angaphandle, ngokuvamile ibhekisela ekuphumeni, nasekudluliseleni amaphakethe edatha ye-IP asuka kusixhumi esibonakalayo se-LAN.
I-LAN: Isetshenziselwa ukuxhuma ekhelini le-IP langaphakathi.Ngaphakathi kwe-LAN kuneswishi.Asikwazi ukuxhuma embobeni ye-WAN futhi sisebenzise i-umzilanjengokujwayelekileshintsha.
I-Wireless LAN (WLAN)
I-WLAN isebenzisa amaza kagesi ukuze ithumele futhi yamukele idatha emoyeni ngaphandle kwesidingo semidiya yekhebula.Izinga lokudluliswa kwedatha le-WLAN manje selingakwazi ukufinyelela ku-11Mbps, futhi nebanga lokudlulisela liwukuthi
Iqhele ngamakhilomitha angaphezu kuka-20.Njengenye indlela noma isandiso samanethiwekhi ezintambo zendabuko, i-LAN engenantambo ikhulula abantu edeskini futhi ibavumele ukuthi basebenze noma nini.
Ukuthola ulwazi noma yikuphi kuthuthukisa ukusebenza kahle kwehhovisi labasebenzi.
I-WLAN ixhumana kusetshenziswa ibhendi yomsakazo ye-ISM (Industrial, Scientific, Medical).Izinga le-802.11a le-WLAN lisebenzisa ibhendi yefrikhwensi engu-5 GHz futhi lisekela kakhulu
Isivinini esiphezulu singu-54 Mbps, kuyilapho amazinga angu-802.11b kanye ne-802.11g asebenzisa ibhendi engu-2.4 GHz nesivinini sokusekela esingafika ku-11 Mbps no-54 Mbps ngokulandelanayo.
Manje iyiphi i-WIFI esivame ukuyisebenzisa ukuze sifinyelele ku-inthanethi?
I-WIFI iyiphrothokholi yokusebenzisa ukuxhumana okungenantambo (empeleni iphrothokholi yokuxhawula), futhi i-WIFI iyindinganiso ye-WLAN.Inethiwekhi ye-WIFI isebenza ku-2.4G noma i-5G frequency band.Okunye
I-3G/4G yangaphandle nayo iyinethiwekhi engenantambo, kodwa izivumelwano zihlukile futhi izindleko ziphezulu kakhulu!
I-Virtual Local Area Network (VLAN)
I-Virtual LAN (VLAN) isho ubuchwepheshe benethiwekhi obuvumela amasayithi akunethiwekhi ukuthi ahlukaniswe kalula abe ama-subnet ahlukene anengqondo ngokwezidingo, kungakhathaliseki indawo akuyo.
Isibonelo, abasebenzisi ezitezi ezihlukene noma eminyangweni ehlukene bangajoyina ama-LAN ahlukene njengoba kudingeka: Isitezi sokuqala sihlukaniswe ingxenye yenethiwekhi engu-10.221.1.0, futhi esitezi sesibili sihlukaniswe
10.221.2.0 ingxenye yenethiwekhi, njll.
