A samambure nomusimboti. musimboti oparesheni

Network nomusimboti, zvimwe aizivikanwa somunhu nomusimboti - mumwe controller kuti rinobatanidza akawanda Ethernet-mano mumwe chete Network chidimbu. Mano chokuita nomusimboti Via internet optic kana coaxial netambo. Rinoshandiswa kuti chinangwa ichi uye Yakakoswa Pair. Nheyo kushanda rakanaka nomusimboti: nayo Anowanza zvose vakapiwa mashoko omumasherufu uye anovatuma zvose zvakabatana zvengarava.

Hub network, uyewo mamwe marudzi concentrators, ine Qualitative maitiro. Chokutanga, chokupika uye mutengo kunoenderana nokuwanda nomusimboti zvengarava. The zvakawanda Ethernet-kwakabatana mano payo, nani chokupika uye mari concentrator. Kazhinji, nomusimboti iri akashongedzerwa ane kunyange nhamba cheap car insurance, ane nhamba anoda kubva mana kusvika 24, asi dzimwe mhando vane outputs shanu. Kuwanda zvengarava zvinogona yakawedzera tichibatanidza akawanda cascade they hubs. Nokuti kubatana kwakadaro neimwe nomusimboti ane connector.

It ane nomusimboti uye mumwe maitiro inokosha - kumhanya kungatonziwo uye tama date omumasherufu. Vamwe hubs vanokwanisa uye zmenyat ake kumhanya ari kuwanda gumi zana megabits por wechipiri. In akadaro mano, zviri kuchinja nenzira mbiri: kana zvaitika kana manually vachishandisa mumwe chinja. In ichi yakatarwa nokukurumidza zvinoshanda zvose zvinoshingaira zvengarava. hubs siyana uye nomumbure zvenhau mhando. Kazhinji, basa iri anoenda internet optic wire kana hangaiwa yakakoswa, asi pane hubs inotsigira mamwe marudzi zvenhau. Panewo hubs kuti vakavhengana marudzi, akadai kutsigira "chemasanganiswa" ari yakakoswa maviri kusvika coaxial waya.

Nheyo yokuvhiyiwa kukwana chaizvo hubs. A date packet vaibva chete mugero, pomumbure nomusimboti kuti makopi ose asara migero chokuita kwazviri, izvo zvinoderedza zvikuru kumhanya Indaneti nokuti zvose Web mano vari chokuita nomumbure Via chimwe chiteshi. Kana omumasherufu vaviri zvakakopwa panguva, kudhumhana kunogona kuitika, i.e. kudhumhana akafanana anonongedzera umo vamwe mashoko akarasika. Dzimwe mhando hubs vanodzivirirwa kwemotokari zvakawandisa. Kazhinji, vari kwakavakirwa yakakoswa peya. Kana zvichibvira chokubvisa chimwe kukundikana mudziyo, apo nomusimboti zvakabatana Via coaxial waya, disables yose chidimbu pakarepo.

Zvinokanganisawo musimboti kushanda kuti nomusimboti uye mashoko kuchengeteka. Kana kombiyuta iri chikamu munharaunda nzvimbo network, kwegadziriro umboo omumasherufu anosvika mamwe nodes zvose. Nokuda kwaizvozvi, zvose pachavo zviruva network, dzepaIndaneti, mavara echivande, forum, uye dzimwe private Data anogona ngakuzivikanwe nhengo zvose samambure ichi. Nezvikonzero izvi, USB-AC Hub ari kuramba yatsiviwa nemambure nomusimboti kana chinja. mudziyo uyu akave nokugamuchira yakakanganiswa wenyaya "Smart Hub" kusiyana pakati kero Mac dziri kombiyuta zvakarukwa uye anotumira mashoko chete kuti chengarava rokushandisa-vakasarudzwa. Saka Mabhokisi nepakati rimwe buffer, iyo kunotadzisa panowanikwa kwemotokari, zadzisa, uye leakage kuti mashoko mitsetse. Nemhaka rakavimbika uye mari yakaderera, asi haizoshandisi vari kuwedzera kushandiswa kumba mugadziriro, apo hubs iri rinenge haritengeswi.
