Waa maxay kala duwanaanshaha?
Hal dariiqo oo lagu kala soocayo noocyada kala duwan ee naqshadaha shabakada kombiyuutarka waa mugga ama miisaanka. Sababaha taariikheed, warshadaha isgaadhsiintu waxay ku xiran yihiin nooc kasta oo naqshad ah sida shabakadda aagga . Noocyada caadiga ah ee shabakadaha degaanka waa:
- LAN - Shabakadda Aagga ee Degmada
- WAN - Shabakad Wideen ah
- WLAN - Shabakadda Aagga Wareegtada ah
- Aagga - Shabakadda Aagga Sare
- SAN - Goobta Aagga Kaydinta, Shabakadda Aagga Nidaamka, Shabakadda Aagga Shabakadda, ama marmarka qaarkood Shabakadda Waaweyn Meesha
- CAN - Shabakadda Aagga Campus, Shabakadda Xakamaynta, ama mararka qaarkood Shabakadda Aagga Kown
- PAN - Shabakada Goobta Shaqsiga
LAN iyo WAN waa labada qaybood ee asaasiga ah ee ugu muhiimsan ee shabakadaha degaanka, halka kuwo kale ay soo baxeen farsamooyin horumarineed
Xasuuso in noocyada shabakadu ay ka duwanyihiin topolojiyada shabakadaha (sida baska, giraanta iyo xiddig). (Eeg sidoo kale - Horudhac Taakulaynta Nadaamka .)
LAN: Shabakadda Aagga ee Degmada
LAN wuxuu isku xiraa aaladaha shabakada fog fog ahaan. Dhismaha xafiiska xidhiidhka, dugsiga, ama guriga badiyaa waxay ka kooban tahay hal LAN, mararka qaarkood hal dhisme ayaa ku jiri doona dhowr LAN yaryar (laga yaabi karo hal qol), marmarna LAN wuxuu soo dhexgeli doonaa koox dhismayaasha ku dhow. In shabakadda TCP / IP, LAN badanaaba looma hirgeliyo sida shabakad IP ah.
Marka lagu daro in meel bannaan oo la shaqeynayo, LAN-yada waxaa sidoo kale jira kuwo iska leh, kontaroolo, oo maamula qof ama urur. Waxay sidoo kale u muuqdaan inay isticmaalaan teknoolojiyada isku xirnaanta, ugu horreyntii Ethernet iyo Token Ring .
WAN: Shabakad Wideen ah
Sida ereyga macneheedu yahay, WAN waxay leedahay masaafo badan oo jireed. Internetku waa WAN-ga ugu weyn, oo kuxiran Dunida.
WAN waa goobo juquraafi ahaan loo kala qeybiyo ee LAN-yada. Qalabka shabakada ee loo yaqaanno router wuxuu LAN-yada u xawilaa WAN. Shabakada IP-ga, router wuxuu ku hayaan cinwaanka LAN iyo cinwaanka WAN.
WAN waxay ka duwan tahay LAN-ka dhowr siyaabood oo muhiim ah. Inta badan WANs (sida Internetka) ma laha hay'ad kasta laakiin waxa ay ku jirtaa mulkiilaha ama mulkiilaha loo qaybiyey ama loo qaybiyey. WANs waxay u muuqdaan inay isticmaalaan tiknoolajiyada sida ATM-yada , Muuqaalka Xakamaynta iyo X.25 si ay ugu xirmaan meelaha fog.
LAN, WAN iyo Shabakadda Guriga
Guryaha sida caadiga ah waxay u shaqeeyaan hal LAN waxayna ku xiraan internetka WAN iyada oo adeeg bixiyaha Internetka (ISP) adoo isticmaalaya modem broadband . ISP waxay bixisaa cinwaanka IP-ga ee modem-ka, iyo dhamaan kombiyuutarada shabakadda guryaha oo isticmaalaya cinwaanada IP ( kuwa gaarka loo leeyahay ). Dhamaan kombiyuutarada ku jira LAN-ka guriga ayaa si toos ah ula xiriiri kara xiriirka, laakiin waa in ay maraan shabakad shabakad dhexe, sida caadiga ah router broadband , si ay u gaarto ISP.
Noocyada kale ee Shabakadaha Aagga
Iyadoo LAN iyo WAN ay yihiin kuwa ugu caansan shabakadaha caanka ah ee ku xusan, waxaad kaloo inta badan arki kartaa tixraacyo kuwa kale ah:
- Wireless Wireless Area Network - Labbo ku salaysan nidaam tiknooloojiyada shabakadda Wi-Fi
- Shabakadda Woqooyiga Magaalooyinka - Shabakad udhiganta aag muuqaal ah oo ka weyn LAN laakiin ka yar WAN, sida magaalo. Man waxaa sida caadiga ah leh oo ay maamusho hal shirkad sida hay'ad dawladeed ama shirkad weyn.
- Aagga Nawaaxiga Campus - Shabakad udhexeeya LAN-yada badan laakiin ka yar MAN, sida jaamacad ama meherad ganacsi maxaliga ah.
- Nawaaxiga Aagga Kaydinta - Wuxuu u xawilaa serverka aaladaha kaydinta macluumaadka iyada oo loo marayo teknoolijiyada sida Fiber Channel .
- Shabakadda Aagga Nidaamka (oo sidoo kale loo yaqaano Network Area Network) - Xiriirada kombiyuutarada sare leh oo leh xawaaraha sare ee xarkaha qaabeynta xirmooyinka.
