Computer Network zvinhu pfungwa

History of kombiyuta network ine yakatangira kubvira panguva kunzwisisa munhu vanofanira kubatanidza kadambari, uye zvimwe zvinhu makombiyuta akawanda kuti pamwe yakawanda mashoko, uyewo kuchengetwa, kubudiswa uye kupararira yakawanda mashoko. kombiyuta networking mamiriro anogona kutakura zvakasiyana-siyana mashoko, asi zvichida chinonyanya kukosha zvinoriumba, izvo zvinosanganisira kombiyuta Network zvinokosha pfungwa nokuda kuvaka izvo dzichakurukurwa pazasi, ndizvo zvibereko interworking.

Kuedza kunzwisisa nyaya dzakadai kombiyuta network kuti dzinokosha pfungwa unofanira kuziva nyore. Pasina ruzivo urwu, nemambure haazombofi hunomubatsira sezvavanofanira kuita, uye izvi zvinosanganisira kurasikirwa nguva uye pfuma zvavakanga vachida kuita hombe.

Saka, zvinokosha Dzidziso kombiyuta network - interworking zvinoreva. Zvinokosha kucherechedza kuti maronda mano aya ndechimwe kukurumidza kuwedzera. Huru chinangwa mari interworking ndiko kupa zvakabatana vanoshandisa, vakabatana huru, uye kakawanda kuparadzirwa pasi hombe zvakarukwa nzvimbo dzomunharaunda.

Computer Network zvinokosha pfungwa anosanganisira mhando matanhatu zvigadzirwa, pakutevedzera interworking.

repeaters

Repeater chinonzi Hardware zano anoshanda ari mumuviri rukoko OSI muenzaniso uye zvinopa mukana bundling vaviri zvakarekodhwa rezvebonde zvikamu.

concentrators

Mashandiro concentrators ndiyo basa vanomhanyisa akaunganidzwa, anopa kubatana mumwe hwebetsero chidimbu uye pemambure mudziyo. Kune mhando dzakawanda concentrators aimiririra pusa, kushingaira uye vakangwara.

mabhiriji

Izwi rinoreva nzira iyo zvakagadzirirwa kupararira umboo omumasherufu pakati emimbure miviri. Mabhiriji zvinoita kuti mamiriro ezvinhu apo zvirongwa uye protocols vava kufunga yaisanganisa rezvebonde yose. Kuwedzera umboo kutapurirana, ramazambuko zvinogona kuitwa rokuchenesa.

routers

With routers vakatakura musoro kubatana zvaida vakaparadzana network. Panguva iyoyowo vakabatana network vanoshandisa chete Protocol. Zviri pachena kuti router - nayo protokolozavisimye mudziyo, izvo zvinofanira rusununguko kukwanisa kuramba zvimwe hwokutiparadza protocols. Ndicho pamberi routers mu pomumbure rinoitawo kuti kuvapo muzvizhinji kuti packet hutachiwana nzira. Uyezve router - a "akangwara" mudziyo kuti anogona kuona Zvakanyanya Kunaka Panguva Yepamuviri nzira nerimwe packet kubva zvakawanda zvichibvira pakutengeserana.

pakashama

Vakawanda tsanangudzo rokuti "pasuo", anoti dzidziso iyi chero Hardware kana yekombiyuta, yakagadzirirwa nokubatanidza peya dissimilar gadziriro. Mupfungwa iyi, resuo anogona kunzi sangano Server kana kuwana Server.

Chokwadi chokuti basa iri pakuyera siyana "layered" Anovagarisa pasina routers, mazambuko uye repeaters anogona anoshanda chete pamwero mumwe vakuru vakuru (ichi kunogona samambure, rimwe gwara kana chaiko layer azvaitwa). Uyezve routers, mabhiriji, repeaters havagoni kuita date kutendeuka.

haizoshandisi

Chinja - zano ane chinangwa chikuru ndechokudzibatsira Redirect chiyamuro Data kune mumwe outputs. Somuenzaniso, panguva chinja chiyamuro Data omumasherufu vakagamuchira, uye goho rayo kwakabatana kuna Ethernet bhazi. In musimboti ichi, mudziyo achazivikanwa somunhu Ethernet chinja

The chinja anofanira kuva nzira aripo kuronga zvakafanira kubatana, uyewo maturusi kutendeutsa chiyamuro ruzivo kupinda yakarurama pamanyorerwo ari goho.
