Ethernet enehana a me kona ulu

Ethernet enehana - ka loa, he pono ole no ka hoʻolālā o kūloko latike. I kēia mau lā kā lākou helu aku i ke kii o ka elima miliona. Inā mākou e kamailio e pili ana i kamepiula 'ē aʻe, a i lako pono me ka mea ulana pukapuka, pepa, ke hoʻohana ma Ethernet enehana, ua ikaika nui ae la lakou.

He aha ke ano o keia manaʻo i loko o ka pilikia hoohalike? Kēia kūkākūkā hae, a i ka nānā 'ana ma luna o ka ke kahu moku, pukapuka Izernet Panel. Ua? Ac? E Xerox, ia i hoʻokō i loko o ke kanahiku-lima o ka makahiki, no ka mea hope kenekulia. Oiai keia hana i ua ho'āʻo nui mamua i loko o ka Radio pukapuka o ke Kulanui o Hawaii. A i loko o ka lua o ka hapalua o na sixties o ka iwakalua kenekulia. A laila mākou e hana me ka dukima ki ina hana like o kaulele komo i kekahi, he pono ole Radio kaiapuni. Kēia papa hana ua kapaʻia ka wā Aloha.

Ethernet-enehana ma ka makahiki kanawalu o ka iwakalua kenekulia i loli. Companies ma December, Intel a me Xerox me Kāʻeokūlani, hana a paʻi i ka hae no ka Ethernet 2 i ulanaʻia. Kona kumu i ka coaxial uwea, a ua lilo ka loa nā mana o ka hui kālepa Ethernetʻenehana hae. A no ke aha la keia mana ua kapaia Ethernet DIX ole 2.

Ma muli o kēia hae? Ac? Kekahi, i kapaia o IEEE 802,3. He mea nui i loko o like me kona, hoʻokomo, akā kānaka okoa, Ethernet 'ike loea i kēia nō i. Oiai ka hou mana i kekahi mau pae MAC a me LLC, me kona kaikuaana me nā pae i hui i loko o hoʻokahi Kanal. Mākou DIX-i ho'ākāka 'hoʻonohonohoʻia kēia makau' ia Kaha Hola Pūnaewele i mea ole o ka hou mana. A me ka mea iki okoa ka lākiō hiʻohiʻona,, i ka i kā mākou a me ka palena iki maoli nui like 'ole no nā ia hae naʻe.

Ethernet IEEE 802,3 enehana ua pinepine haawiia ia, oiai ka Ethernet DIX kapa wale, me kekahi hoailona. He ua hana i ka mea e hoomaopopo i ka hou hae, mai ka mua kekahi. Ke kaumaha ma muli mea 'ano o ka āina a puni, ua hoʻohana', Ethernet IEEE 802,3 maʻamau 'enehana hoʻolako likeʻole likeʻole (10 Base-5, pu me ka 10 Base-2, 10Base-T kekahi s10Base-FL, a, ma hope, 10Base-FB).

I ka hae, a ua aponoia kapaia kanaiwa-lima o ka makahiki o ka iwakalua kenekulia, Fast Ethernet. He nani, e olelo aku ia ia mea,ʻaʻole kūʻokoʻa ma na mea he nui i ka mahalo. Kēia keʻae i ka nui, e hoike ana ia mea he mea ano o ka papa kuhikuhiE hoʻokō 802,3 - pauku 802.3i. Like me, i aponoia i ka hou kekahi i loko o 1998 - Gigabit Ethernet, a ua ho'ākāka 'ia i loko o kekahi pauku 802.3z keia kumu palapala.

E hoouna aku, a loaa aeaie 'ike ma luna o ke kaula no a pau o ke kino, ahu iho i loko o Ethernet enehana, a hoakaka i ka bandwidth o umi megabits no kekona, ua hoʻohana' Manchester kuhi. Loa a pau Ethernet mau hae, pu me na hope elua,'ālike iaoia ua hoʻohana 'ia no ka hookaawale ana meakino iʻikepili EYI. Ua Ua kapaia CSMA / CD.

Mākou a pau holo ma luna o ka mea a pau mōʻaukala o ka 'enehana. A mau lā aku nei oia i ua kanahā nā makahiki o. I loko nō o kēia, ia mea nō mahalo. I kēia lā, o ka papa, ma laila nō 'ike loea hou a me ka oi pono, akā, loa paha, Ethernet' ike loea e ia na mea he nui na makahiki, e hoomakaukau i ko kakou mea ulana pukapuka, no ka mea, Ua ike loea, he mea hiki, ana hoʻohana no na makahiki.
