Izinethiwekhi Zendawo Yendawo Zichazwa
Incazelo: I- LAN imelela iNethiwekhi Yendawo Yendawo. Kuyinto inethiwekhi encane (kuqhathaniswa ne- WAN ) ehlanganisa izindawo ezincane ezifana negumbi, ihhovisi, isakhiwo, i-campus njll.
Ama-LAN amaningi namuhla agijima ngaphansi kwe- Ethernet , okuyi- protocol elawula ukuthi idatha idluliselwa kanjani phakathi komunye umshini komunye kunethiwekhi. Kodwa-ke, ngokufika kwenethiwekhi engenazintambo, ama-LAN amaningi futhi ayaziwa angenawaya futhi ayaziwa njenge-WLAN, amanethiwekhi angendawo angenawo angaphandle. i-protocol eyinhloko ebusa uxhumano nokudluliswa phakathi kwama-WLAN yi-WiFi protocol eyaziwayo. Ama-LAN angenantambo angaphinde agijime ngobuchwepheshe be-Bluetooth, kodwa kuncane kakhulu.
Uma uxhuma amakhompyutha amabili ukwabelana nedatha, une-LAN. Inombolo yamakhompyutha axhunyiwe kwi-LAN ingaba ngamakhulu amaningana, kodwa isikhathi esiningi, ama-LAN akhiwa ngemishini engaphansi kweshumi nambili, njengoba umqondo ngemuva kwe-LAN ukumboza indawo encane.
Ukuxhuma amakhompyutha amabili, ungawaxhumanisa kuphela usebenzisa ikhebula. Uma ufuna ukuxhuma okuningi, khona-ke udinga idivayisi ekhethekile ebizwa ngokuthi ihabhu , efana nokusabalalisa nephuzu lokuxhumanisa. Amakhodi avela kumakhadi ahlukene e-LAN amakhompyutha ahlangana ehabhu. Uma ufuna ukuxhuma i-LAN yakho kwi-intanethi noma kwinethiwekhi enkulu yendawo, khona-ke udinga router esikhundleni sehabhu. Ukusebenzisa ihabhu kuyindlela evamile kakhulu futhi elula yokusetha i-LAN. Kukhona ezinye izakhiwo zenethiwekhi, ezibizwa ngokuthi ama-topologies. Funda kabanzi ku-topologies nokuklama kwenethiwekhi kulesi sixhumanisi.
Awunayo kuphela amakhompyutha ku-LAN. Ungaphinda uxhume amaphrinta namanye amadivayisi ongawabelana ngawo. Isibonelo, uma uxhuma iphrinta ku-LAN bese uyilungiselela ukuba yabelwe phakathi kwabo bonke abasebenzisi ku-LAN, imisebenzi yokuphrinta ingathunyelwa kuleyo phrinta kuzo zonke amakhompyutha e-LAN.
Kungani Sisebenzisa LAN?
Kunezizathu eziningana zeziphi izinkampani nezinhlangano ezitshala imali kwi-LAN endaweni yazo.Izi zithi:
- Ukuxhumana okusheshayo nokwabelana kwamafayela nezinye izinsiza phakathi kwabasebenzi nabahlanganyeli.
- Ukushintshaniswa kwezinhlelo zolwazi. Isibonelo, esibhedlela, i-LAN izovumela ukuthi idatha eyodwa yedatha ifinyeleleke kuyo yonke iminyango njengokuthi akukho ukuphindaphinda kwedatha, ayikho i-redundency, futhi okubaluleke nakakhulu ukuthi kukhona ukuhambisana okuphelele kwedatha.
- I-LAN ivumela ihadidi ebiza kakhulu ukuthi yabelwe, njengoba kuchaziwe ngenhla.
- Ama-LAN avumela abasebenzisi ukuthi bahlanganyele amalayisense e-software, ngokufanelana nokulondoloza izindleko.
Izidingo Zokusetha I-LAN
- Amakhompiyutha namadivayisi afakwe i-NIC efanele (amakhadi wombukiso wenethiwekhi). Isibonelo, futhi i-Ethernet LAN izofuna wonke amadivayisi ukuthi abe namakhadi e-Ethernet noma ama-adapter ukuze ikhebula lixhumeke. Inethiwekhi ye-WiFi idinga wonke amadivayisi abe ne-adaptha ye-WiFi.
- Idivayisi ephakathi, njengehabhu, router, ibhuloho noma isango.
- Ixhuma izintambo uma kwenzeka i-LAN ifakwe.
- I-software yokuphatha i-LAN. Isistimu yokusebenza yesimanje isivele isofthiwe yezinsizakalo zokuphathwa kahle kwamanethiwekhi.
