Ndechipi rinoita Network michina?

Chero kambani ano (zvebhizimisi chemahofisi, fekitari, online chitoro it.d.) rinoshandisa nokuda kwayo kushandiswa Network kombiyuta. Izvi imhaka yokuti kana paine makombiyuta maviri kana kupfuura saka zviri nyore wokushandura mashoko zvakafanira pakati namano. Izvi, Chokwadi, anobvumawo kudzora hurongwa. mutoro basa kwakadaro zvinotora pamusoro pemambure michina.

Imhandoi michina? Zviri yakatarwa mano kuti zvinodiwa kushanda yakarongeka network. Izvi zvinosanganisira routers, haizoshandisi, hubs, nama noukomba, uye zvichingodaro. Uyewo, mano aya rakakamurwa tichishingaira uye pusa Network michina. Nhasi ndinoda kukuudzai zvishoma pamusoro wokutanga chimiro.

Saka, basa rezvebonde midziyo - chaiwo zvemagetsi kuti vane zvimwe zvivako "akangwara". Zvikurukuru izvi zvinosanganisira routers (marshtutizatory) pamwe haizoshandisi.

A chinja ndiwo mudziyo kuti network izvo makombiyuta Exchange Data mumwe nomumwe. Kushandiswa kubatanidza achazoburuka pomumbure kwemotokari, asiwo kudzivirira kurasikirwa mashoko zvitange. zvakarukwa michina iyi vanoshingaira zvose vakakwanisa uye unmanaged.

Unmanaged ushande nheyo, rinonziwo algorithm kero obsolescence. mudziyo uyu ane zvakaipira kuti unovapo kubva pakuti kugamuchira kero packet, zvisina inowanika yakakodzera tafura, kuti chinja iri inoumbwa nhepfenyuro chikumbiro, zvoita kuti restart ane kukurukurirana mugero uye Somugumisiro kuderedza Network unongotaura. Uye izvozvo nomumbure zirokwazvo kuzvidzivirira panguva pezviri kurwisa.

Panyaya akakwanisa haizoshandisi, nemambure midziyo ari kushingaira kushandiswa kuwedzera kumhanya nokutuma mashoko, uyewo kuvandudza Network unongotaura. Pasi pavo Network ine mukuru azvipire kudzivirirwa. Zvakawanda basa uchishandisa pachiyero wechipiri pemambure OSI womuenzaniso.

Hwokutiparadza haizoshandisi vava kushanda pazuva rechitatu chechetere akabatana. Izvi zvinoita kuzvishandisa sezvo chinoumba pemambure. Mune mamwe mamiriro ezvinhu, izvi namano chinhu unogona kutsiva routers.

Ikozvino ngatitaurei pamusoro chii chinonzi router. Zviri chinoshingaira rezvebonde mudziyo anoshanda ari wechitatu OSI chechetere. Zvinonzi chakagadzirirwa kuwana munyika richikurukura vomunharaunda uye anoronga munhu vakagovera zvebhizimisi network, izvo chinopa mukana mushandi mumwe mashoko zvavanoda. Uyewo unogona kushandiswa pave firewalls kuti adzikatidza kwokunze rezvebonde kupindira.

Asi pane Hardware sefa zvinoshandiswa pakati emimbure. Dzinonzi firewall. Ko vakazvitsaurira servers hwaakange Software iri akagadzawo (Operating System, Virtual Private Network uye firewall). Ivo zvinopawo zvakarukwa kuchengeteka uye kuita nekupinda kutyisidzira kuti Internet mari.
