Ethernet zvemichina chacho kukura

Ethernet michina - rakajairika kuti sangano vomunharaunda network. Nhasi nhamba yavo kwazvo mufananidzo mamiriyoni mashanu. Kana isu kutaura nezvemakombiyuta, izvo vakapakata nomumbure makadhi, uchishanda Ethernet zvigadzirwa, ivo zvakawanda.

Ko pfungwa iyi rakamanikana mupfungwa? Izvi networking mureza, iyo yakavakirwa mutyairi wendege zvakarukwa Izernet Network. Rakanga yakataurwa Xerox, zvakanga rakatangwa muna-reshanu manomwe gore, achiri rokupedzisira remakore. Kunyange zvazvo nzira iyi akaedzwa ipapa ari redhiyo Network of University of Hawaii. Zvino yechipiri yezana sixties remakore rechimakumi maviri. Zvadaro tinoshandisa ose nzira kurongwa kuwana rwakafanana redhiyo ezvinhu. Nzira iyi inodaidzwa apo Aloha.

Ethernet-michina muna masere gore remakore rechimakumi maviri hwachinja. Makambani ari December, Intel uye Xerox anorenda zvakasikwa uye akabudisa mureza Ethernet 2 Network. Its hwaro hwaiva coaxial waya, razova kupfuura ichangopfuura shanduro chepamusoro Ethernet Michina mureza. Ndokusaka shanduro iyi anonzi Ethernet Dix kana 2.

Kubva musi mureza uyu vakava mumwe, wainzi IEEE 802,3. Ane muzvinhu zvakawanda nowakautangira, asi siyanei, ichi Ethernet michina achine. Nepo shanduro itsva akasiyana siyana Mac uye LLC, nomukoma wake vaviri siyana vakanga yakabatanidzwa kuva mumwe mugero. We Dix-yakajeka configuration shanduro kuongorora dzakati kuti haisi shanduro itsva. Uye zvakaita reshiyo siyanei, zvisinei, kufadza uye shoma puranga hukuru vaviri nemitemo chete.

Ethernet IEEE 802,3 zvemichina inowanzonzi akataura, ukuwo Ethernet Dix akadana nyore, pasina chinhu zviratidzo. Izvi zvinoitwa kuti kusiyanisa mureza mutsva kubva yaimbovapo. Zvichienderana hworudzii Mhoteredzo rinoshandiswa, Ethernet IEEE 802,3 mureza Michina inopa zvakasiyana siyana (10 Base-5, pamwe 10 Base-2, 10Base-T zvakare s10Base-FL, uye, pakupedzisira, 10Base-FB).

Mureza, rakanga vakagamuchirwa rinonzi gore remakore rechimakumi maviri makumi mapfumbamwe namashanu, Fast Ethernet. Hazvina kunaka kuti haisi rakazvimirira muzvinhu zvakawanda. Izvi zvinopupurira chokwadi kuti rondedzero iri nyore huru mukwanisi 802,3 - chikamu 802.3i. Saizvozvowo, imwe itsva rakagamuchirwa muna 1998 - Gigabit Ethernet, iyo inorondedzerwa chimwe chikamu 802.3z ichi gwaro inokosha.

Kutumira nokugamuchira binary mashoko rwonzi zvose mumuviri rukoko muna Ethernet zvemichina, chinopa bandwidth pakati megabits gumi chete wechipiri, rinoshandiswa Manchester romutemo. Absolutely zvose zvinodiwa Ethernet, pamwe vapedzisira maviri, akafanana nzira inoshandiswa nokuda kuparadzana svikiro panguva date hutachiwana. Inonzi CSMA / CD.

Tose akamhanya pamusoro munhau yose mabikirwo. A Mazuva mashoma apfuura akanga atova nemakore makumi mana okuberekwa. Pasinei neizvi, kachiri. Nhasi, Chokwadi, kune zvitsva uye yamunenge ano, asi Ungangove, Ethernet michina achava makore akawanda akawanda kupa samambure yedu nokuti akavimbika, anoshanda, vakabudirira kushandiswa emakore.
