He aha nā modems? Ke Kumuhana o ka hana. Nā'ano o nā modems

Ke ho'opili mua'oe i kahi pona a i'ole kekahi kamepiula pilikino i ka Pūnaewele mai nā po'e'ike'ole i'ike'ia, hiki ke nīnau i ka nīnau: "He aha nā modems a me ke kumu i makemake'ia ai lākou?" Ma kēia'atikala e hō'ulu'ulu i nā modems, a me kahi algorithm no ko lākou ho'okomo'ana a ho'onohonoho'ana, 'O ka mea, me ka pilikia'ole, hiki i ka mea akamai kelepona polokalamu ke koho a hana i ia'ano hana.

He aha ia?

'O ka mea mua, e nānā i nā'ano modems. He He kūikawā ke keʻena i loko o ka lolouila, i ua papahana no ka pili i ka 'ē aʻeo ka. Ua ho'okumu'ia ka hua'ōlelo "modem" ma o ka ho'ohui'ana i'elua mau hua'ōlelo. 'O ka mua o kēia ka modulator. No laila, i kapa'ia ka'enekini he'olika kūikawā, i ho'opi'i i ka hō'ailona. A'o ka lua he demodulator. 'O ia ke'ano o ka hana e ho'ololi ai i ka modulator. Ho'oiho kekahi o lākou i ka hō'ailona a ho'oku'u i ka hō'ailona, a'o ka lua ua loa'a a ua ho'ololi. No laila, i kēia manawa, ua pili ka hapa nui o nā kamepiula pilikino me ka pūnaewele. I kēia manawa, ua loli ke'ano, a ua kahe wikiwiki'ia lākou mai kēia māhele o ka mākeke ma nā kāleka kāleka. He mau ki'eki'e ki'eki'e ko lākou, a ua ho'olako'ia ka hapanui o lākou. Akā na'e, aia nā'ōpili ahokore i'ole e loa'a kahi'oko'a'ē a'e.

Iāhea'oe e pono ai?

I kēia manawa, e maopopo ana iā mākou nā mea e pono ai lākou. I ke kumu,'ekolu mau manawa like'ole. 'O ka mua o kēia mau mea e ha'alele nei i nā mea i hala. Aia ia i loko o ke'ano'o kahi pilikino pilikino me kēia mea kani a me ka laina kelepona i ka pūnaewele. I kēia manawa ua ho'ololi'ia e kā kāleka kāleka. A ua emi ka uku, a he nui ka wikiwiki. A'o ka hilina'i o ka pilina ma kēia hihia, he'oi aku ka maika'i o ke ki'eki'e. Akā, no ka pūnaewele "Client-Bank" e like me kēia mea ('o ka hihia'elua). Me ke kōkua'ana o ia mea, ua ho'ohui ka mea mo'owāki i ka kikowaena o ke ke'ena kālā. Me ka ha'alele'ole i ke ke'ena, hiki iā ia ke ho'ololi i kahi kālā a i'ole e nānā i ka loa'a o nā kālā ma ka'ike. 'A'ole pono ka wikiwiki i kēia hihia. Akā, pono ka pale hilina'i ma ka pae kūpono. I kēia manawa, he nui nā hui i loko o kēia'ano papa hana me nā kālā. 'O ka hope hope loa, inā makemake'ia nā modems, inā hele kekahi kanaka ma kahi nui. Makemake'o ia i kahi pūnaewele pūnaewele ka'awale. I kēia hihia,'o ka nīnau: "He aha nā'ano modems, a no ke aha i makemake'ia ai lākou?" - ho'opuka'ia e ia iho. Me ke kōkua o nā'enehana'enehana'ē a'e, hiki'ole ke ho'oholo i kēia paena.

Ma o ka palapala ohi

E like me ke'ano o ka ho'opau'ana, ua māhele'ia kēia mau māhele i'elua'ano: loko ('o ia ho'i, ua ho'okomo'ia i loko o ka pūnaewele pūnaewele) a me nā mea i waho (no ka ho'onui'ana i ke kamepiula, ka pona a i ka papa. No ka mea hope, pono'oe e ho'ouka i kahi ho'ololi holomua hardware (inā loa'a kekahi) i kahi kūpono. I kēia hihia, pono ke kūpono i kēia nīnau: "He aha ke'ano o ka modem?" He helu ma'amau a like'ole paha - ua ho'oholo'ia e ka laina laina laina. No nā'ōpili kelepona wale nō ka mea mua. Ke ho'ohana wale nei nā pūnaewele pūnaewele wale nō i kēia hae. No laila, no nā'ōnaehana pūnaewele'a'ole i hā'awi'ia kēia kī. Pono kahi mea e pono ke nānā. Ma luna o nā papa makuahine ua ho'ohui'ia (e like me ka ho'ohui) i nā mea like. Akā'ānō,'a'ole lākou i loa'a hou ma nā kamepiula pilikino hou.

Ma ka pili

'O ka lua o ka ho'ohui'ana, i ho'ohana'ia i kēia manawa, e pili ana i ke'ano o ka pilina. E like me ia, ua māhele'ia kēia mau pūnaewele i ka laina a me ka laina'ole. I ka hihia mua, ua ho'olako'ia kahi pūnaewele kūikawā kahi i ho'okomo'ia ai ka pa'i kelepona. Ma nā pūnaewele kahiko, hiki iā'oe ke kama'ilio ma ke kelepona a hana paha ma ka pūnaewele. I kēia manawa, ho'ololi kūikawā'ia kēlā mau mana'o. Hiki iā'oe ke noho pū ma ka pūnaewele i ka manawa ho'okahi a kama'ilio ma ke kelepona. He modem ADSL kēia. He aha ia? 'O kahi mea ho'ololi kūikawā e ho'oka'awale i ka kūkā'ana a me ka hō'ailona kiko i nā alapine like'ole. No ka hopena,'elua mau kahawai'ikepili i lawe'ia ma luna o ke kīpona like. Ma ka lua o ka hihia, ho'olako'ia ka'ikepili ma ka ho'okele hili'ole me ka'ole o nā'ili.

Ma ke'ano o nā'enehana kāko'o

Ho'onohonoho kēia koho i nā pono pūnaewele wale nō. E like me ia, no nā'ano penei: GSM (i kekahi manawa i kapa'ia'o 2G), 3G a me LTE (inoa'ē a'e 4G). 'O lākou a pau i hope. 'O ia,'o 3G ke hana ma'alahi ma kahi pūnaewele GSM. Eia kekahi, ua kānalua nā mea ho'ohana i ke'ano o ka USB modem. Aia i loko o kēia'ano-ke kumu e hana'ia ka hapa nui o kēia mau hanana. I ka nānā'ana, he makani māmā e hā'awi ana i ka'ikepili pūnaewele'ole. No ka nele, ua ho'olako'ia me kahi pahu pahu SIM. Ho'ohui'ia ia i kahi pūnaewele USB pūnaewele ma kahi kamepiula pilikino.

Hana

Hiki ke ho'oka'awale'ia nā mea hana o ia mau mea i'elua papa. 'O ka papa mua o kēia mau inoa'oihana kū'ai'ole a'ike'ole'ia,'o ia ho'i'o Sierra (ke ho'omaka ke kumukū'ai mai nā 180 rubles) a me Sprint (he 120-150 rubles ka uku o ia mau mea). Akā'o ka papa'elua he'oihana kaulana a ki'eki'e. Ke kū'ai'ia nei lākou ma lalo o nā poli Pantech a me Huawei. 'O ke kumukū'ai no lākou i kēia manawa, he'eono haneli a'oi a'e paha. Akā'oia'i'o kēia no nā'ōnaehana pūnaewele. Ho'onui pinepine kēia i ka nīnau o ke'ano 3G modem. He polokalamu'oihana kēia ('ano like me kahi pūnaewele māmā), kahi i ho'okomo'ia ai ka pahu SIM o ka mea ho'okele pūnaewele, a me ia pūnaewele i hā'awi'ia i ka'ike'ike'ike. I ka huli'ana, aia i waena o nā pūnaewele wili'ia nā kūlana ki'eki'e e noho'ia ana e "D-Link" a me "A-Corp." Pono ia e ho'olohe iā lākou i ka wā e kū'ai ai i kēlā mea ho'ohana. 'O ke kumukū'ai no kekahi mau hi'ohi'ona o kēia māhele e ho'omaka ana mai 120 rubles. Ma ka manawa like, hiki'ole ke kūpono o ko lākou kūlana.

Ho'opilikino

E noonoo oe i ka kaʻina hana no ana i ka Internet mōkema. He aha ka modem Internet? 'O kēia a pau, me ka'ole o nā'oko'a o kēia papa: nā laina a me ka pono'ole. No laila, ke kauoha o ka ho'ololi'ana:

• Ho'ohui. No waho - e ho'onoho iā lākou i ka māla ho'onui o ka pūnaewele ho'okele. Akā, i ka manawa e ho'okomo ai i kēlā mea i loko, pono'oe e wehe i nā uhi'ao'ao o ka pūnaewele pūnaewele PC, e ho'okomo i ka kāleka ma kahi pahu ho'onui, e ho'oponopono a e hō'ili'ili i nā mea a pau.
• Ke ho'ouka'ana i nā ho'okele. I ka hapanui o nā hihia, hiki ke ka'awale wale, a ho'emi'ia ka komo'ana o ka mea ho'ohana i kēia hana. I ka hopena, pono'oe e loa'a i kahi leka e hō'ike ana i ka ho'okomo maika'i'ana o kēia pūnaewele. (Inā'ole kēia hana, pono iā lākou e ho'okomo'ia me ka lima mai ka CD-ROM mai ka pūnaewele pūnaewele paha.)
• A laila mākou e ho'ohui i ka Pūnaewele.
• Ma ka hopena hope, ho'oku'u kākou i ka polokalamu kelepona a nānā i ka hana'ana o ka pilina.

I kekahi mau kumu, pono'oe e ho'ololi i nā kikowaena o ka mea (e like me ke'ano, ho'ololi i ke'ano koho'ana i ke anapili). Ho'ākāka'ia kēia'ike e ka mea ho'olako a me ka mea kelepona.

Hō'ulu'ulu

Ma kēia'atikala, ua hā'awi'ia ka pane i ka nīnau o nā'ano modems a me ke kumu e pono ai. Hiki ke hā'awi'ia nā hana o ia mau mea. Hō'ike'ia ko lākou'ano hana a me nā'ano hana'ē a'e. Ho'okomo pū'ia kekahi'āpana algorithm, a laila e hiki ke ma'alahi a ma'alahi i ke'ano o ia mea no ka ho'ohui'ana i ka pūnaewele kamepiula.
