telefoni Kuyamba:Chida choyankhulirana chakutali chomwe chimatha kutumiza ndi kulandira mawu


1 ntchito zofunika

 

telefoni

Seti ya telefoni imayikidwa kumbali ya wogwiritsa ntchito poyambira komanso pomaliza kulumikizana kwa telefoni, ndipo ndi zida zogwiritsira ntchito matelefoni. Mafoni amakono amatha kuzindikira mafoni ndi zokambirana pakati pa ogwiritsa ntchito kumapeto, zomwe zapangidwa pambuyo pa kafukufuku wa anthu ambiri ndi kusintha kosawerengeka kwa zaka zopitirira zana. Ngakhale masitayilo awo amasiyana mosiyanasiyana, nthawi zambiri amakhala ndi ntchito zotsatirazi:

1. Kusinthana kwamacoustic ndi magetsi

Chifukwa m'pofunika kuchita kuyankhulana mofulumira komanso mtunda wautali, phokoso silingatumizidwe mwachindunji, koma phokoso liyenera kusandulika kukhala chizindikiro chamagetsi (ndiko kuti, magetsi amagwiritsidwa ntchito ngati chonyamulira), ndiyeno chizindikiro chamagetsi chimakhala. kubwezeredwa kumveka pambuyo pofika mbali ina.

2. Off-mbeza chizindikiritso

Pamene phwando loyimba foni litenga foni, chosinthiracho chiyenera kukhala ndi ntchito yodziwa "wina akufuna kuyimba", kotero kuti kusinthako kumakhala kokonzeka kugwirizanitsa.

3. Tumizani chizindikiro

Seti ya foni yodziwikiratu imawongolera ntchito yosinthira mafoni potumiza chizindikiro choyimba, kenako imakhazikitsa kulumikizana pakati pa ma seti awiri amafoni.

4. Lizani belu

Ndiko kuti, pamene gulu lina likuyitana, foni imatha kumuuza mwiniwakeyo ndi mawu akuti: "Wina akuitana."

5. Kulumikizana kwamagetsi

Mu telefoni, zigawo zomwe zimagwira ntchito zisanuzi ndi izi: foni yam'manja, chibelekero, kuyimba (kapena keypad), belu lafoni ndi dera lafoni.

foni yam'manja

Foni ili ndi ntchito yosinthira kumveka kwa mawu a terminal kukhala siginecha yamagetsi, kuyitumiza ku gulu lakutali kudzera mu mzere wa telefoni, ndi kukonzanso chizindikiro chamagetsi choperekedwa ndi gulu lina kukhala liwu (mawu omveka) kuti alankhule. Chizindikiro chosankhidwa (kuyimba kugunda), kudziwitsa winayo za kamvekedwe kakuyimbira ndi ntchito zina. Foni imapangidwa ndi transmitter yomwe imatembenuza mawu kukhala magetsi ndikuwatumiza ku chingwe chafoni, cholandirira chomwe chimabwezeretsa zomwe zimaperekedwa ndi gulu lina ku mawu, kuyimba kapena batani kuyimbira winayo, ndi ringtone yomwe imatumiza. kamvekedwe kakuyitana. Malumikizidwe awa amachitidwa pa foni Yake yogwira ntchito pamzerewu ndi zigawo zina. Pali kabokosi kakang'ono kodzaza ndi tinthu ta kaboni mkati mwa chotumizira, ndipo kutsogolo kwake kumayika mbale yolimba yolimba ya aluminiyamu yonjenjemera. Mbale yonjenjemera imanjenjemera ndikunjenjemera tinthu ta carbon molingana ndi mawu, ndipo tinthu ta kaboni timachita panopa. Ndi digiri ya kukhudzana kwa tinthu tating'onoting'ono, kukana kumasintha kuti apange mawu apano. Pambuyo polandira mawu a gulu lina, wolandirayo amatulutsa mphamvu ya maginito yobwera chifukwa cha kumveka kwa mawu pa koyiloyo, imanjenjemera mbale yachitsulo yogwedezeka, ndi kutulutsa mawu.

Ndi chitukuko chofulumira chaukadaulo wa IT, kuthekera kokonza zida zophatikizika ndikukulirakulira. Kumayambiriro kwa zaka za zana la 21, foni "smart phone" yokhala ndi wothandizira deta (PDA) idawonekera.

Kuphatikiza pa magwiridwe antchito amizere yokhazikika, mafoni anzeru nthawi zambiri amakhala ndi ntchito zowongolera makadi abizinesi akuluakulu, ntchito zoyang'anira mafoni omwe akubwera komanso otuluka, ntchito zopewera kuzunzidwa kwamafoni (telefoni firewall), mabizinesi amakampani amakampani (makadi amkati abizinesi) oyang'anira, ndi ntchito zamaofesi othandizira. Ntchito zambiri za , monga: ndandanda, cholemba, kalendala, chowerengera ndi ntchito zina. Mafoni anzeru oyambilira anali ndi kuthekera kosinthira zidziwitso kudzera pa intaneti yoyimba, ndipo adazindikira ntchito za kutumiza mameseji achidule ndi kulandira mameseji. Ndi chitukuko cha mafoni a m'manja okhazikika ku China kwa zaka pafupifupi khumi, luso lawo lokonzekera lalimbikitsidwa, ndipo ntchito za mafoni anzeru (Smartphone) zawonjezeka pang'onopang'ono.

Mafoni anzeru ali kale ndi kuthekera kogwiritsa ntchito intaneti komanso ntchito zamphamvu zama multimedia. Itha kusakatula pa intaneti, kusewera ma audio ndi makanema, komanso imakhala ndi ntchito monga ma e-mabuku ndi mafelemu apakompyuta. Nthawi yomweyo, ntchito zamafoni anzeru muofesi yothandizira, malonda othandizira, zosangalatsa ndi zina zalimbikitsidwanso kwambiri. Pamaziko a kugubuduza foni yokhazikika yachikhalidwe, ntchito zambiri zamabizinesi ndi ntchito za PDA zimakwaniritsidwa.

7 Chitukuko chamtsogolo

Kukula kwa mafoni apamwamba kwambiri kumapangidwa ndi chitukuko cha mauthenga opanda zingwe. Kapangidwe ka telefoni kakula kukhala ntchito ya IMT-200 yomwe imatha kugwiritsa ntchito kulumikizana kwa satellite pambuyo pa telefoni ya Digital ndi PCS. IMT-200 imathandizira kutumiza zidziwitso mwachangu kwambiri, mautumiki amtundu wa multimedia monga Packet ndi zithunzi. M'tsogolomu, mafoni onse amawu, maulendo olunjika kwa ogwiritsa ntchito telegraph, paging ndi e-mail angagwiritsidwe ntchito kumadera onse a dziko lapansi; ndi kutchuka kwa ma e-mail, maukonde nawonso akuchulukirachulukira. VoIP ndi njira yosasinthika yachitukuko. Mafoni apamtunda omwe alipo kale sangathenso kupereka zosowa za anthu. Ma landline amtsogolo adzakhala ndi makamera ndi zowonetsera zamitundu yamadzimadzi zamadzimadzi, kuti tiwone mbali zonse ziwiri tikayankha foni yapansi.
