Chii chakasiyana?
Imwe nzira yekugadzirisa maitiro akasiyana-siyana emakombiyuta ekugadzirwa kwemakombiyuta ndeyekuwanda kwavo kana kuti zviyero. Nokuda kwezvikonzero zvezvakaitika kare, mushandirapamwe wekutengesa unoreva kunenge mhando dzose dzekugadzira seimwe rudzi rwekushandisa nzvimbo . Nzvimbo dzakasiyana dzehutachiona nzvimbo ndeyokuti:
- LAN - Local Area Network
- WAN - Wide Area Network
- WLAN - Wireless Local Area Network
- MAN - Metropolitan Area Network
- SAN - Storage Area Network, System Area Network, Server Area Network, kana dzimwe nguva Small Area Network
- KUNA - Campus Area Network, Controller Area Network, kana dzimwe nguva Cluster Area Network
- PAN - Personal Area Network
LAN neWAN ndiyo mbiri uye inonyanya kuzivikanwa mapoka emagetsi, apo vamwe vakabuda ne teknolojia yekufambira mberi
Cherechedza kuti mhando dzemagetsi dzinopesana kubva kune unhu hwekunamata (zvakadai sebhasi, mhete uye nyeredzi). (Onawo - Mharidzo kuText Topologies .)
LAN: Local Area Network
A LAN inobatanidza mitambo yepamusoro pane imwe nguva shoma. Chivako chekuvaka mahofisi, chikoro kana imba chinowanzova neLAN imwe chete, asi dzimwe nguva imwe chivako chichava neLAN shomanana (zvichida imwe neimba imwe), uye dzimwe nguva LAN ichaita boka rezvivako zvitsuwa. MuTCP / IP kusungirirana, LAN inowanzomira asi isingashandisirwi nguva dzose seine IP subnet .
Mukuwedzera pakushanda mune imwe nzvimbo shoma, LANs zvakare inowanikwa, inotungamirirwa, uye inotungamirirwa nomunhu mumwe chete kana sangano. Vanowanzoshandisa mamwe magetsi ekubatanidza, zvikuru Ethernet uye Token Ring .
WAN: Wide Area Network
Sezvo izwi rinoreva, WAN inotarisa nzvimbo yakakura yepanyama. IInternet ndiyo yeWAN huru, inotarisa pasi.
A WAN is geographically-dispersed collection of LANs. A network network inonzi router inobatanidza LAN kune WAN. Mu IP kusungirirana, router inochengetedza mbiri yeLAN uye neWAN kero.
A WAN akasiyana neLAN nenzira dzinoverengeka dzinokosha. Mazhinji eWANs (kufanana neInternet) haasi eine sangano rimwe chete asi pane zviripo pasi rose kana kuparadzanisa umiridzi uye hutungamiri. WANs inowanzoshandisa teknolojia yeATM , Frame Relay uye X.25 yekubatanidza pamusoro pemakwikwi akareba.
LAN, WAN uye Home Networking
Vagari vanogara vachishandisa imwe LAN uye vanobatanidza neInternet WAN kuburikidza neInternet Service Provider (ISP) vachishandisa hurukuro yemodem . ISP inopa wani IP yekodhi kumamodem, uye ese makombiyuta ari pamusha webasa anoshandisa LAN (inonzi yakananga ) IP kero. Makombiyuta ose ari pamba LAN anogona kutaura zvakananga kune mumwe nemumwe asi anofanirwa kupfuura nepakati nepasuo remagedhi , kazhinji rouband router , kuti asvike ISP.
Dzimwe Mhando dzeNzvimbo Networks
Kunyange zvazvo LAN neWAN zviri kure nemichina yakakurumbira mitauro inotaurwa, iwe unogonawo kuverenga zvinotaurwa kune vamwe ava:
- Wireless Local Area Network - A LAN inobva pa Wi-Fi wireless network technology
- Metropolitan Area Network - Nhandare inowanikwa nzvimbo yakakura kupfuura yeLAN asi duku kudarika WAN, yakadai seguta. MUMWE anowanzochengetwa uye anoshandiswa nehurumende imwechete yakadai sedare rehurumende kana sangano guru.
- Campus Area Network - A network yakawanda maLAN akawanda asi ari maduku kupfuura MAN, zvakadai seyunivhesiti kana bhizimusi rekambani.
- Storage Area Network - Inobatanidza mavhariji kumadivayisi ekuchengetedza data kuburikidza ne teknolojia yakadai seFiber Channel .
- System Area Network (inozivikanwawo seCluster Area Network) - Liyunyanzvi dzemakombiyuta ekukwirira uye nehupamhi hwekubatanidza mumasangano ekugadzirisa masumbu.
