Chii Ethernet - zvakanakira chikuru paIndaneti samambure

Ndizvo Ethernet, yakasvika pakuzivikanwa ari manonwe ari XX remakore. I tega ichi mhando Lan Robert Metcalfe, uyo akanga achishanda panguva yacho Xerox Corporation. Mukupera '70s Metcalfe akazarura kambani yake 3com, apo akapedza kukura itsva rwokugadzira. Nokufamba kwenguva chakatsiva ipapo huripo mhando omunzvimbo network, uye boka Metcalfe akazova mutungamiri mumunda uyu.

Izwi «Ethernet» rinoumbwa nemashoko Eteri (neEteri) uye mambure (zvakarukwa). Zvino kukuudzai zvakawanda, kuti ndiye Ethernet, uye ndedzipi pfungwa zviri ichi mhando samambure. Izvi mhando samambure ane nyeredzi kana Linear chivako chine velocity pamusoro 10-100 megabits / wechipiri. Pakutanga Ethernet kwaibva coaxial waya, asi nokufamba kwenguva mabikirwo yachinja, uye akatanga kuvaka nomumbure kwakavakirwa faibha-optic waya kana vaviri yakakoswa. Zvino kune vanenge makumi matatu mhando Ethernet network kuti vakasiyana akurumidze, kwakaita nzvimbo yacho, ukuru uye mhando waya. Havasi Miti zvose vakawana dzokutengesa kushanda. Nokuti vaya vanoda kuziva zvose zvinotaurwa Ethernet, isu nyora zvikuru nevakawanda rwokugadzira.

Xerox Ethernet - zvemichina kwakavakirwa coaxial waya ane pamwero kunonyanyisa of 3 megabits por wechipiri. Nadzurudzo StarLan, iyo yakatanga kushandiswa yakakoswa peya. Nokumhanya kubatana ndiro duku - chete megabit 1 pasekondi yoga yoga.

The Michina 10BASE5 coaxial waya transmits mashoko ari aimhanya 10 megabits / wechipiri. Anawo nokukurumidza uye muna StarLan10, asi coaxial wire pano yave yakatsiva zvakamonyororwa peya. Zvadaro, ruzivo urwu rava mhando 10BASE-T, apo mana wakarukwa maviri anoshandiswa.
Munguva dikidiki 100BASE-T yakakoswa-vaviri nokukurumidza chakawedzera kuti megabits zana / wechipiri. Izvi mhando yambokurukurwa mberi. 100BASE-FX transmits mashoko pamusoro internet optic wire ari chinhambwe 10 makiromita ari kumhanya mumwe zana megabits / wechipiri. The 1000BASE-T anoshandisa mbiri mana vytye, uye daro akaenzana zana mamita. Mune nadzurudzo 1000BASE-LH kure yawedzera 100 km. ekupedzisira maviri inonyanya kumhanya, zviri 1000 megabits muzana wechipiri.

Ethernet, izvo zvinosanganisira zvose okunatsiridza izvi hwakabatana pamwe controller chaiyo revatema pamusoro hurongwa bhodhi.

Zvino ngationei zvakanakira iyi mhando samambure. Chinonyanya kukosha zvinobatsira - zviri Kuwanikwa. The kombiyuta zvakabatana pomumbure dzose nguva, uye usati Indaneti hapana chikonzero dhayira kukwira Provider. Over Ethernet chezvematongerwe kunzi was mutsetse, umo Modem hadzisi kudiwa. Chimwe chakanakira - kumhanya kuti anobvumira Ethernet Protocol. Speed inopiwa symmetric, kana swinging faira kana nhume. Uyezve, imwe Ethernet-kubatana inogona Achishandisa chepamusoro kana munzvimbo samambure umo makombiyuta zvose zvichava riwanikwe chete kumhanya kubatana.

Security munyika yanhasi Ethernet-Network chiri vakarongeka. Kazhinji, vabereki vanopa inodzidzisa chaiyo IP-kero kuti tibu- kusazivana iri kombiyuta iri "World Wide Web." Zvechokwadi, kwete muduku mukana nomumbure akadaro nyore chaizvo kubatanidza. Haufaniri kuva Modem kana Software chaiyo, chete vane nomumbure kadhi iri yakavakwa zvinenge zvose motherboards. Izvi imhaka pakururama uye Accessibility uye pasi mari Ethernet-kubatana. Tinorasikirwa shoma zvizhinji kupfuura yose connectivity kuburikidza raundi-up Modem.

Nokufamba kwenguva, izvi mhando samambure uchanyatsotsunga nyore. Kare, pane shanduro kuti anopa nokukurumidza anenge 10 gigabits / wechipiri. Pakazosvika pakati gumi iri kutarisirwa goho michina, iyo ichapa munhu nokukurumidza akaenzana 1 terabit / wechipiri. With anoshamisa akadai maonero nechimwe anonzwisisa Ethernet chii, achada kubatanidza kuti samambure.
