Ua hāʻawiʻia nā modems hōʻano hou i nā modems lōʻihi lōʻihi
ʻO kahi modem ʻO ia kekahi mea lako pūnaewele nāna eʻae i kahi kamepiula e hoʻouna a loaʻa i nāʻikepili ma luna o kahi laina kelepona a iʻole ke kaula uila a iʻole ka hili. I keʻano o ka hoʻokuʻuʻana i kahi laina laina analog,ʻo ia ka manawaʻoi loa i hiki ke komo i ka pūnaewele, nāʻike converts i unuhi i waena o nā hiʻohiʻona analog a me nā kikowaena i ka manawa kūpono no kaʻike pūnaeweleʻelua. I keʻano o nā modems hōʻemi maʻamau i kēia lā, ua maʻalahi ka hōʻailona aʻaʻole pono e hoʻololi i ka analog-a-digital.
Ka Moʻolelo o nā Modems
ʻO nā polokalamu mua i kapaʻia nā modems i hoʻololi i nāʻikepili helu no ka hoʻoiliʻana i nā laina laina laina maʻamau. Ua kālaiʻia ka wikiwiki o kēia mau modems ma ka baud (kahi mahele o ka inoa i kapaʻiaʻo Emile Baudot),ʻoiaiʻoiai i kūkuluʻia e kaʻenehana'elepihi, ua hoʻololiʻia kēia mau mea i ka lua ma ka lua . Ua kākoʻo nā wānana pāʻoihana mua i ka holo wikiwiki o 110 bps a ua hoʻohanaʻia e ka US Department of Defense, nā lawelawe leka, a me nāʻoihana nui.
Uaʻike maʻalahi nā Modem i nā mea hoʻohana i ka hopena o nā makahiki 70 a hiki i nā 80s ma keʻano he papa hoʻolaha lehulehu a me nā lawelawe leka e like me CompuServe. A laila, me ka paʻiʻana o ka Pūnaewele puni honua ma ka waenakonu a me ka hopena o nā makahiki 1990, uaʻikeʻia nā modems kelepona e like me keʻano o kaʻike pūnaewele i nāʻohana he nui a puni ka honua.
Hoʻoponopono Kūlohelohe
Ua hoʻohanaʻia nā modems i hoʻohanaʻia ma nā laina kikowaena e hoʻololi i nāʻikepili ma waena o nāʻano analog i hoʻohanaʻia ma nā laina kelepona a me ka palapala kikowaena i hoʻohanaʻia ma nā kamepiula. Hiki i nā pūnaewele modem waho waho i kekahi kamepiula ma kekahiʻaoʻao a me ka laina kelepona ma kekahiʻaoʻao. I ka wā i hala aku nei, ua hoʻokomo kekahi mea hana kamepiula i nā modems i loko o kā lākou papapihi kamepiula.
Hoʻokomo i nāʻikepili pūnaewele hōʻano hou i kēia me ka wikiwiki o 56,000 mau huakaʻi ma ka lua. Eia naʻe, nā palena o ke keleponaʻana o ke keleponaʻana i nā kaona o nā modem i 33.6 Kbps aiʻole i lalo i ka hana.
I ka hoʻohuiʻana i kahi pūnaewele ma o ka modem dial-up, e hana mau nā'ōnaeho ma o ka mea'ōlelo i nā leo kūikawā i hakuʻia ma ka hoʻounaʻana i nāʻikepili pūnaewele ma luna o ka laina leo. Ma muli o keʻano o ka hui pūnaewele a me nā hiʻohiʻonaʻikepili like me kēlā me kēia manawa, hoʻolohe ka leo hana kani i ka mea hoʻohana e hōʻoia i ka hanaʻana o ke kaʻina hana.
Nā Modems Teleband
ʻO kahi modem wilile e like me nā mea i hoʻohanaʻia no DSL a iʻole kele pūnaewele pūnaewele e hoʻohana i nā hōʻailona hōʻailona e hiki ai ke piʻi i nā pūnaeweleʻoihana kiʻekiʻe ma mua o nā kālaikaho-loiloi kahiko. Hoʻonui pinepineʻia nā modems broadband i nā modems lōʻihi. ʻO nā modems pūnaewele heʻano o ka modem lākiho e hoʻokumu i ka pūnaewele pūnaewele ma waena o kekahi pūnaewele pūnaewele a me kahi pūnaewele pūnaewele .
Kuhiʻia nā modems lōʻihi i waho i kahi kelepa uila o ka home a iʻole ka mea'ē aʻe ma kaʻaoʻao hoʻokahi a me ka'ōnaewele pūnaewele waho e like me ke kaula leka i kekahi. ʻO ke kelepona aiʻole ka puka puka e kuhikuhi i ka hōʻailona i nā mea a pau o kaʻoihana a iʻole ka home e like me ka mea e pono ai. ʻO kekahi o nā mea loea me ka laulima me kahi modem i hoʻohuiʻia e like me kahi pūnaewele pono'ī hoʻokahi.
He nui nāʻaila pūnaewele e hoʻolako i nā lako lako modem pono i kā lākou mea kūʻai aku me ka ukuʻole a no ka uku makahiki. Eia naʻe, hiki ke kūʻaiʻia nā modems maʻamau ma waena o ka puka kūʻai kūʻai.
