Ethernet uye Network Hubs Tsanangudzo
Mumakombiyuta ekutengesa, kambani kaduku, kari nyore, ine zvigadzirwa zvemagetsi zvinobatana nemakombiyuta akawanda pamwechete.
Kusvikira pakutanga kwema 2000s, maEbset hubs aishandiswa zvikuru kumatarenda emusha nekuda kwekunzwisisa kwavo uye kudhura. Kunyange zvazvo mabhiriji ejw.org akaisa panzvimbo yavo mudzimba, mahubhu achiri kushanda chinangwa chakanaka. Kunze kweEthernet, mamwe maitiro mashomanana emitambo hubs anovapowo kusanganisira USB hubs.
Mamiriro eEthernet Hubs
Chigaro chinonzi rectangular box, inowanzoitwa yepurasitiki, iyo inogamuchira simba rayo kubva kune rimwe rutivi rusvingo. Nhandare inobatanidza yakawanda makombiyuta (kana mamwe maikiriti emagetsi) pamwe chete kuti iite imwechete yekunamatira. Pane iyi network network, ose makombiyuta anogona kutaura zvakananga nemumwe.
Ethernet hubs dzinosiyana mumhanya (network data rate kana bandwidth ) vanotsigira. Ethernet hubs yakatanga kupa 10 Mbps chete yakarongedzeka. Mitambo mitsva yehubs yakasimbisa 100 Mbps kutsigirwa uye inowanzopiwa zvose 10 Mbps uye 100 Mbps simba (zvinonzi kaviri-speed kana 10/100 hubs).
Nhamba yezvikepe zveEthernet hub dzinotsigirwawo dzakasiyana. Nhamba ina-ne5-port Ethernet hubs dzinowanikwa mumakombiyuta emisha, asi hubhu huri nane uye 16-port hubs inogona kuwanikwa kune dzimwe nzvimbo dzekumba neimba. Huru dzinogona kushamwaridzana kune imwe neimwe kuti dziwedzere nhamba yose yezvigadzirwa nhare yehubhu inogona kutsigira.
Makwegura Ethernet hubs aiva akaenzana muhukuru uye dzimwe nguva ane ruzha sezvo aive neefomu dzakagadzirwa mumafani ekugadzirisa unit. Nzvimbo idzi dzemazuva ano dzakanyanya kuduku, dzakagadzirirwa kufamba, uye dzisingatauri.
Passive, Active uye Injere Hubs
Zvinhu zvitatu zvinokosha zvehubs zviripo:
- passive
- inoshanda
- akachenjera
Mavara asingasviki anoita kuti zviratidzo zvemagetsi zvisati zvaitika vasati vazviparidzira kune network. Kushanda hubs , kune rumwe rutivi, vanoita izvi kukurudzira, sezvinoita rudzi rwakasiyana rwezvakatsaurirwa kambani inonzi repeater . Vamwe vanhu vanoshandisa izwi rokuti concentrator kana vachitaura kune imwe nzvimbo yepamusoro uye mutambi wenhambadziro pakutaurirana paanotaura nezvebasa rinoshanda.
Inyanzvi hubs inowedzera zvimwe zvikamu kune imwe nhandare inobatsira iyo inonyanya kukosha kumabhizimisi. Chinhu chinonzwisisika chinowanzoita stackable (yakavakwa nenzira yakadai kuti zvikamu zvakawanda zvinogona kuiswa imwe kumusoro kweimwe kuchengetedza nzvimbo). Intelligent Ethernet hubs inowanzobatanidza masimba ekuchengetedza kure nekwakapfuura kuburikidza neSNMP uye virtual LAN (VLAN) kutsigirwa.
Kushanda nema Hub Hub Ethernet
Kuti ubatane, boka remakombiyuta rinoshandisa kambani ye Ethernet, tanga ubatanidza kambani yeEthernet muyuniti , uye taurirana imwe mugumo wedhafa kune imwe kakombiyuta yenzvimbo yekambani yenethiwekhi (NIC) . Zvose maEbset hubs anogamuchira RJ-45 connectors e-standard Ethernet cables.
Kuti uwedzere ruwaya kuti uwane mamwe madivayiri, Ethernet hubs inogonawo kushamwaridzana, kushandura , kana kufamba.
Apo E Hubet Hub inodiwa
Ethernet hubs inoshanda seVheji 1 zviyero mumuenzaniso weOSI . Kunyange zvazvo hubs yakafanana nekushanda, inenge yese yose yeEthernet mitambo yezvishandiso nhasi inoshandisa network switch technology pane, nekuda kwebasa rekushanda kwe switch. Chimbichimbi chinogona kubatsira kwechinguva kudarika chinoputsika network switch kana apo kushanda hakusi chinhu chakakosha pamusangano.
