Nzvimbo dzakawanda dzedhizha dzenhare dzinoshandisa teknolojia yeEthernet
Ethernet ndiyo teknolojia inonyanya kushandiswa munhare dzenharaunda dzenharaunda ( LAN s). A LAN ishungetedzo yemakombiyuta uye mamwe mashizha emagetsi anofukidza nzvimbo duku yakadai sedzimba, hofisi, kana kuvaka. Inoshandiswa mukusiyana kune nzvimbo yakawanda yenzvimbo (WAN), iyo inotarisa nzvimbo dzakawanda dzenharaunda. Ethernet ipurogiramu yenethiwekhi iyo inotarisira kuti dhiyabhorosi inoparidzirwa sei pamusoro peLAN. Inyanzvi inonzi inonzi IEEE 802.3 protocol. Iyo protocol yakashandura uye yakagadziridzwa pane nguva yekuendesa dhigirii nekukurumidza kwegigabit kwechipiri.
Vanhu vazhinji vakashandisa teknolojia yeEthernet upenyu hwavo hwose vasingazvizivi. Zvinonyanya kuitika kuti chero hutano hwehutachiona muhofisi yako, kubhangi, uye kumba ndiEthernet LAN. Izvo zvekombiyuta nemakombiyuta emakombiyuta zvinouya nekambani yeEthernet makadhi mukati mazvo saka vakagadzirira kuungana kune Ethernet LAN.
Zvaunoda mune imwe Ethernet LAN
Kuti uise wired Ethernet LAN, unoda zvinotevera:
- Makombiyuta nemagetsi ekubatanidza. Ethernet inobatanidza chero kakombiyuta kana zvimwe zvigadzirwa zvemagetsi kumatare aro chero bedzi iyo device ine Ethernet adapta kana network network.
- Network interface makadhi mumakoni. A network network interface ingangosanganiswa mukati maamaiboard yekombiyuta kana kuiswa zvakaparadzana muchigadzirwa. Iwewo une USB shanduro dzemakadhi eEthernet akadai sekunze dongles. Kadhi yeEthernet inozivikanwa senhare yekambani. Iine ports uko iwe unokwanisa kuunganidza tambo. Iko kunowanzove mabhii maviri, imwe yeJJ-45 jack inobatanidza tambo dzisina kushandiswa (UTP) dzisina kushandiswa uye imwe ye coaxial jack.
- A router, hub kana kuti gedhi rekubatanidza zvigadzirwa zvako. Chimbichimbi chigadzirwa chinoshanda senzvimbo yekubatanidza pakati pezvigadzirwa pamutambo. Inoumbwa nemitambo yakawanda yeRJ-45 yaunogadzira tambo.
- Cables. Tsamba dze UTP dzinowanzoshandiswa muEthernet LANs. Iyi ndiyo imwechete yekambani inoshandiswa kumitambo yefoni, asi mafuta, ane mairi masere akakomberedzwa emawindo emarudzi akasiyana mukati. Kuguma kunoputika neJJ-45 jack, iyo inowanikwa yakawanda yeJack-11 jacks iyo inowedzera mufoni yako yenyika. Apo Ethernet inopinda pane imwe imba kusvika kure, coaxial cable inoshandiswa. Iyi ndiyo yakafanana kabheji ine ye-round single-core jack yaunoshandisa paTV.
- Software yekutarisira network. Mazuva ano mashandiro ekushandura sehuwandu hweWindows, Linux uye MacOS zvishoma zvinokwana kugadzirisa Ethernet LANs. Chechitatu yepurogiramu software iyo inopa mamwe maitiro uye kutonga kwakanaka kunowanikwa.
Ethernet Inoshanda Sei
Ethernet inoda ruzivo rwekodhidhiyo mumashandisi epakombiyuta kuti inzwisise nzira iri shure kweEthernet protocol yakazara. Heino tsanangudzo yakajeka: Apo mishonga iri mumutambo inoda kutumira dambudziko kune imwe, inoona mutakuri, iyo iyo foni huru inobatanidza zvose zvigadziri. Kana iri kureva rusununguko hapana ari kutumira chero chinhu, inotumira data packet pamutambo, uye dzimwe mimwe magetsi chengetedza pakiti kuti uone kana ari mupiki. Munhu anogamuchirwa anodya peji. Kana paine kakato nepaketani mumugwagwa mukuru, chigadziro chinoda kutumira chinodzosera kumashure kwechiuru chemakore chechipiri kuti chiedze zvakare kusvikira chinogona kutumira.
