Topology "indandatho": ngebuhle nebubi

inethiwekhi yomphindwa - umuntu wenyama futhi ngendlela enengqondo ukuze sihlanganise iqembu amakhompuyutha inethiwekhi. Okuvame kakhulu inethiwekhi yomphindwa - "isondo", "Inkanyezi" "indandatho". Ngamunye wabo kunezinzuzo zako kanye nebubi, futhi isetshenziswa kuye ngokuthi isimo. Bonke ngandlela-thile asetshenziswa ekwakhiweni LANs yesimanje. Ake sibheke izici zabo zokhiye, ufunde kahle izimfanelo ezinhle nobuthakathaka ngamunye wabo.

"Njengoba iThire '

Lolu hlobo inhlangano inikeza inethiwekhi yendawo usebenzisa ikhebuli olulodwa, ngawo hlanganani bodwa zonke workstations ukusetshenziswa. Ngamunye wabo kutshela wonke amakhompyutha exhunywe kwi-line, kodwa munye kuphela owamukela idatha, ikheli lapho kuvezwa iphakethe. Abanye basuke nje indiva ulwazi.

I yomphindwa "ibhasi ezivamile" ngempela esetshenziswa terminators ezisebusweni semikhawulweni ikhebula main futhi amasignali bagibele ngokufaka nalokho ukuze bagweme ukucabanga nezenzo zabo. Ngaphandle kwalezi amadivayisi kunethiwekhi olunjalo belungaphelelwa ngempela bakha ukushayisana, ngenxa okuyinto umsebenzi evamile ngeke kwenzeke. Yiqiniso, izingxabano namanje kuphakama, kodwa sibonga terminators inombolo yabo incane. Uma konke lokhu okwakwenzeke, esiteshini umane athumele iphakethe futhi emva okungahleliwe isikhawu kuchazwe algorithm.

Izinzuzo yomphindwa "isondo"

Lokhu zokuxhumana kunezinzuzo eziningana phezu kwezinye izindlela. Phakathi kwabo - izindleko ongaphakeme kanye kalula ukwakhiwa indalo yayo. Hlela inethiwekhi yendawo ilula ngokwanele, kodwa udinga ukufinyelela "wesitimela ezivamile" bese uxhuma kwi-PC nge nezixhumi ekhethekile. Lokhu yomphindwa kudinga ukusetshenziswa eliphansi inethiwekhi yentambo, ngoba isebenzisa izingxenye ezincane kuphela yokuxhuma "ibhasi" kuya workstation.

Kunengqondo ukusebenzisa "ibhasi ezivamile" emahhovisi amancane noma, Ngakolunye uhlangothi, emigwaqweni emikhulu yokuxhuma namanethiwekhi amaningi ndawonye. Enye inzuzo yale yomphindwa wukuthi uma zokugwema ukuphuka eyodwa yokusebenza kwenethiwekhi akuyona workstations ethintekile. Abahlanganyeli esele baqhubeke nomsebenzi wabo sengathi akwenzekanga lutho.
