A topology na kwamfuta cibiyoyin sadarwa

Wannan mas'ala ta hanyar sadarwa yakan haifar da wani wadannan da definition. A cibiyar sadarwa ne mai tarin abubuwa, wanda aka kafa ta da na'urorin cewa aika da kuma aiwatar da bayanai. International Organization ga Standardization yankin cibiyar sadarwa yana bayyana a matsayin bi da bi bit-daidaitacce watsa bayanai tsarin tsakanin masu zaman kansu, amma juna a hanya ta musamman na'urorin.

Architecture of kwamfuta networks ne cewa cibiyoyin sadarwa yawanci zauna a wani yanki, saboda haka suna da yawa shared a kan wani yankin akai. Akwai gida, yankin da kuma duniya networks.

Amfanin, wanda ya bada sadarwar na sirri kwamfutar sau da yawa sun hada da ikon raba albarkatun, data rabuwa, da rabuwa da software, da rabuwa da CPU da albarkatun, da yiwuwar shirya wani Multi-mai amfani mode.

Daban-daban sadarwar siffofin ba da ikon haifar da wani iri-iri na kwamfuta networks sukayi fassara. Wadannan halaye sun hada da topology na kwamfuta cibiyoyin sadarwa, su dalili, da jerin ayyuka, ka'idodinta management (za a iya Karkasa da kuma rarraba), ya sauya sheka hanyoyin, damar hanyoyin, iri kafofin watsa labarai watsa, data kudi , da sauransu.

Bari mu zauna a kan irin wannan muhimmanci ra'ayi kamar yadda wani kwamfuta cibiyar sadarwa topology. A kowace kwamfuta cibiyar sadarwa, kowane workstation jiki da alaka da sauran sadarwar tashoshi. A dangane da aka sanya a cewar wani takamaiman tsari, wanda ake kira da topology na kwamfuta cibiyoyin sadarwa. Saboda haka, topology na kwamfuta cibiyoyin sadarwa da aka inherently kwatanta jiki sadarwa a kwamfuta cibiyar sadarwa cewa, ya nuna wani takamaiman aiki tashar, iya dauri ga juna. A kan abin da irin halin da aka zaɓa topology na kwamfuta cibiyoyin sadarwa, yi dogara a kan matakin da aiki yadda ya dace da kuma AMINCI na workstations ne da yanar-gizon, kazalika da lokaci lokaci ake bukata kira ga fayil uwar garke. Bugu da kari topology yana da tasiri kai tsaye a kan hanya na samun da cibiyar sadarwa, wanda za a amfani.

Don kwanan wata iri kwamfuta cibiyar sadarwa topologies biyar, amma yadu amfani uku: bas topology, zobe topology, da topology na "star."

Bus topology aka zaci cewa dukkan cibiyar sadarwa nodes za a haɗa a wani wucin gadi cibiyar sadarwa ta hanyar guda na USB. Cable ƙarshe ya kamata ku bauta a matsayin resistive load. A guda na USB goyon bayan guda tashar data. A bas topology na USB kira bas. Networks gina a kan bas, suna dogara ne a kan coaxial na USB.

A zobe topology ya same ta ganin a cikin sauki tsara kwamfuta cibiyoyin sadarwa. All workstations, bisa ga wannan topology suna da alaka da ta biyu wabtansu. Idan muka yi la'akari da sauran dangane zane a cikin cibiyar sadarwa halitta da wani zobe topology, za ka iya ganin wani abu mai kama da zobe. A data a cikin irin networks za a iya daukar kwayar cutar a cikin guda shugabanci, da kuma duk workstations aiki a matsayin repeaters, samun da amsawa ga fakitoci magana da su, sa'an nan da canja wurin sauran data fakitoci bin wani workstation wanda aka located "nisa da tushe".

A mafi yadu amfani a yau samu wani gida cibiyar sadarwa, gina bisa ga wata star topology. A cikin irin wannan networks, data na'urorin diverge daga sananniyar batu, bayar da wata cibiya, a na'ura mai ba da hanya tsakanin hanyoyin sadarwa ko wani cibiyar sadarwa canji. Idan muka kwatanta da cibiya a matsayin star cibiyar, sa'an nan diverging daga shi zai yi kama da haskoki - Saboda haka wannan topology, da kuma samu da sunan. Babban amfani da wani star topology a kwatanta da zobe ne da yiwuwar bada dama na masu zaman kansu damar zuwa cibiyar sadarwa bayar da wani na'urar. A wannan yanayin, kowane na'urar ne iya amfani da watsa matsakaici, ko da kuwa da sauran na'urorin a cibiyar sadarwa.
