LVS - ubuchwepheshe samanje

Okwamanje a okwandile esikhulu kakhulu amanethiwekhi computer. Nabo, abasebenzisi bangasebenza okufanayo izinsiza, izinhlelo, imininingwane, ngokuqondile workstation yabo.

Uyini LAN?

Uhlobo oluvame kakhulu amanethiwekhi - wendawo endaweni amanethiwekhi.

LVS - inethiwekhi yekhompyutha yokuxhuma abasebenzisi umshini lwendawo ukuqhela nomunye. Nakuba uhla inethiwekhi kuze kube amakhilomitha amaningana, ngokuvamile esetshenziselwa uxhumano kwama-computer ibanga elincane. Ngokuvamile, lo mshini zokusebenza elilodwa ibhizinisi noma ekhaya PC.

ukucushwa kwe-LAN

Ukucushwa ingashiwo LANs nokulawula iseva ngaphandle (kuyalingana).

Umngani inethiwekhi yendawo

Ngo amanethiwekhi enjalo, wonke amakhompyutha zifana ngokuya Ukucaciswa. Umngani-to-LAN - inethiwekhi yendawo lapho workstation ngamunye ongenza yonke imisebenzi etholakalayo kokubili amaklayenti kanye iseva. Ukuze kahle load sekulinganisa eziningi iqhaza ikhompyutha LAN akukwazi ezingaphezu kuka 10. Ngaphandle kwalokho, yonke yokusebenza kwenethiwekhi uyahlabeka.

ukuphathwa Network iseva (lokuhweba)

In esinjalo LAN ingenye amakhompyutha wenza ezahlukene kangcono, wememori, nezinye izinkomba. Lokhu PC inikezwa yiseva. Amaseva ku-LAN - kukhona amakhompyutha nge ukusebenza ephakeme ezinkulu wememori kuqhathaniswa umshini wendawo yomsebenzisi. Kuyinto lowo inikeza esibonakalayo kwamanye amakhompyutha inethiwekhi, izitolo kanye uhlela amafayela umphakathi ukuthi ufinyelele kuzo, edlulisa idatha iklayenti ngesimo ulwazi ukucubungula noma umphumela. LAN, lapho iseva isetshenziswa kuphela ukuze ihlanganise idatha ezivamile, esibizwa amanethiwekhi ne iseva ifayela ozinikele. Kanye izinhlelo ezinjalo, kukhona LAN, lapho iseva futhi kwenziwe futhi ukucutshungulwa kolwazi, kanye Iklayenti uthola kuphela umphumela. Lokhu okuthiwa amaklayenti-server izinhlelo.

LAN yomphindwa

Zonke amakhompyutha akwinethiwekhi ezingeni eziphathekayo sixhumene. LAN yomphindwa - indlela ukuxhuma umshini wendawo. Manje LANs compounds asetshenziswa izindlela ezifana ibhasi, inkanyezi, futhi indandatho.

ibhasi yomphindwa

Ngo-LAN, okuyinto inhlangano sihlelelwe ngokwaleli yomphindwa isetshenziswa ebandleni ikhebuli olulodwa, wajoyina umsebenzisi kukhompyutha yakho yendawo. Ngakho, ulwazi kusuka umshini oqhubeka bonke abanye. I workstation, okuyinto abhekiswe idatha, ukukhethela Imininingwane ofiselekayo kusukela emfudlaneni jikelele.

Izinzuzo LAN ibhasi yomphindwa:

• ukungasebenzi omunye amakhompyutha wendawo ngeke kuthinte ukusebenza kwezinye imishini namanethiwekhi e jikelele;
• ukuhlelwa elula kanye nomklamo LAN;
• izindleko ephansi yezintaba okudlekayo (nge endaweni engaba encane isinyathelo, isibonelo, enhlanganweni efanayo).

Okumbi yomphindwa:

• Ikhebula umonakalo ivinjiwe inethiwekhi jikelele;
• uhla esilinganiselwe futhi abasebenzisi ezimbalwa;
• isivinini elincane (kuye ngokuthi isibalo amakhompyutha akwinethiwekhi).

"Inkanyezi" yomphindwa

I yomphindwa yalolu hlobo kuhilela nokuxhumana amakhompyutha sendawo nge imishini inethiwekhi (labaculi noma ihabhu) ukuthi ihlinzeka uxhumano okucishe kufane nalokhu imishini ukusebenza. esiteshini ngasinye ixhunywe kudivayisi aphethe ngokusebenzisa ehlukile ikhebula inethiwekhi ikhadi. Njengoba ifomu yangaphambilini ye yomphindwa, idatha aphumayo liyatholakala kubo bonke amakhompyutha akwinethiwekhi, futhi ngeke kuphela yamukelwe ngumsebenzisi zona ahloselwe.

Izinzuzo yomphindwa:

• lula ukuhlela umsebenzi omusha;
• ukusebenza kahle eliphezulu;
• iphutha okusheshayo noma ikhebula ikhefu;
• ekusebenzeni inethiwekhi musa kuthinte iphutha imishini ngabanye wendawo.

Okumbi yomphindwa:

• ukwehluleka unit central eyeka ukusebenza yonke inethiwekhi;
• inombolo yabasebenzisi uvinjelwe inani emachwebeni unit central;
• ukusetshenziswa uneconomical e-USB;
• yokufuna izindleko Hub (noma ezinye imishini inethiwekhi).

Topology "indandatho"

LAN ukufakwa okwenziwé ngokuvumelana nemithetho yalolu hlobo yomphindwa, aqukethe uchungechunge imishini oxhumene ukusebenza, likhula lakha isiyingi. Idatha kuleli cala bavela computer eyodwa kuya kwenye, futhi bahlale yokuthi anqotjhiweko.

Izinzuzo yomphindwa "indandatho":

• Awekho amanye amanani imishini inethiwekhi (ihabhu, umzila);
• ikhono ukudlulisa idatha phakathi amakhompuyutha kanyekanye.

Okumbi yomphindwa:

• ukusebenza yonke inethiwekhi kuncike ijubane computer ngamunye;
• Ingungu yensimbi ekhaliswayo ngokushaywa ikhebula noma ukwehluleka computer eyodwa ikhiyiwe ukusebenza ezweni inethiwekhi;
• yinkimbinkimbi isethaphu kanye ukucushwa;
• Inhlangano emisebenzi emisha ngesikhathi thwebula umsebenzi LAN.

I yomphindwa we "indandatho" cishe ungalokothi elisetshenziswa umkhuba ngenxa yokungazethembi jikelele, kodwa kuncike ukuhlela kabusha ahlukahlukene.

Okwamanje, cishe akukho inhlangano angakwenza ngaphandle LAN. Okuningi ezivamile "inkanyezi" inethiwekhi yomphindwa ngenxa ukwethembeka futhi wokubekezelela iphutha. LAN yomphindwa "indandatho" Ngokuphambene, izinganekwane angahlangabezani izinkomba zezempilo nokuphepha yesimanje. Nokho, LAN sisonke ziye zaba ingxenye yezimpilo zethu kanye neqhaza Ukuphumelela kwanoma iyiphi ibhizinisi.
