Webusaiti Yogulitsira Zamakono
Mapulogalamu apakompyuta akhala akugwiritsira ntchito makina ochezera ailesi m'zaka zaposachedwapa, komanso kufalikira kwa mafoni a m'manja, mapiritsi, ndi zipangizo zina zamagetsi. Zipangizo zamakono zomwe zimathandiza kuti magetsi apitirize kusintha ndikupita patsogolo ndi ogwiritsira ntchito zomwe amagwiritsa ntchito kuti agwirizane nawo.
Maselo Ogwirizanitsa Webusaiti
Mafoni apamtundu amadziŵikanso ngati ma intaneti. Zapangidwa ndi "maselo" omwe amagwirizana ndi wina ndi mzake ndi ma foni kapena masewero. Maselo amenewa ndi malo omwe nthawi zambiri amakhalapo, ali ndi transceiver imodzi, ndipo amagwiritsa ntchito maulendo osiyanasiyana a wailesi. Ma transceivers awa ndi nsanja zazitali zomwe zakhala zofala mu dziko lathu logwirizanitsa. Amagwirizana wina ndi mzake kuchotsa mapaketi a deta, mawu, ndi mauthenga-pomalizira pake amabweretsa zizindikiro pamakono apamwamba monga mafoni ndi mapiritsi omwe akuwongolera. Ophatikiza amagwiritsa ntchito nsanja za wina ndi mnzake m'madera ambiri, kupanga mapulogalamu ovuta omwe amapereka chithunzi chokwanira kwambiri kwa olembetsa.
Maulendo
Mafupipafupi a mawonekedwe apakompyuta angagwiritsidwe ntchito ndi olembetsa ambiri pa nthawi yomweyo. Malo osungirako magetsi ndi mafoni a m'manja amayendetsa maulendo kuti agwiritse ntchito otumiza mphamvu zoperewera kuti athe kupereka mautumiki awo mosavuta.
Otsogolera Mobile Network Providers
Omwe amapereka ma intaneti ku US ambiri, kuchokera ku makampani ang'onoang'ono, am'deralo mpaka aakulu, osewera odziwika bwino m'munda wa televizioni. Izi zikuphatikizapo Verizon Wireless, AT & T, T-Mobile, US Cellular, ndi Sprint.
Mitundu ya Mapulogalamu a Mobile
Mitundu yosiyanasiyana ya matelofoni apakompyuta amagwiritsidwa ntchito popereka mauthenga apakompyuta kwa ogwiritsa ntchito. Akuluakulu ogwira ntchito amasiyana chifukwa cha zomwe amagwiritsa ntchito, choncho zipangizo zamakono zimamangidwa kuti zigwiritse ntchito luso lamakono. Mafoni a GSM samagwira ntchito pa ma CDMA, ndipo mosiyana.
Mawutchi omwe amagwiritsidwa ntchito kwambiri ndi GSM (Global System for Mobile Communication) ndi CDMA (Code Division Multiple Access). Kuyambira mwezi wa September 2017, Verizon, Sprint, ndi US kugwiritsa ntchito ma CDMA. AT & T, T-Mobile, ndi ena ambiri operekera padziko lonse amagwiritsa ntchito GSM, kuti ikhale yogwiritsidwa ntchito kwambiri pogwiritsa ntchito mafoni a m'manja. LTE (Long-Term Evolution) yakhazikitsidwa ndi GSM ndipo imapereka mphamvu zowonjezera ndi kuthamanga.
Kodi Ndi Bwino: GSM kapena CDMA Mobile Networks?
Kulandira chizindikiro, kuthamanga, ndi liwiro kumadalira zinthu zambiri. Malo a wogwiritsa ntchito, wopereka chithandizo, ndi zipangizo zonse zimagwira ntchito. GSM ndi CDMA sizisiyana kwambiri ndi khalidwe, koma momwe amagwirira ntchito.
Kuchokera kwa wogula, GSM ndi yabwino chifukwa foni ya GSM imanyamula deta zonse za makasitomala pa SIM khadi yochotsedwa; Kusintha mafoni, makasitomala amangosintha SIM card mufoni yatsopano ya GSM, ndipo imagwirizanitsa ndi intaneti ya GSM. Gulu la GSM liyenera kulandira foni iliyonse yodalirika, ndikusiya ogula ufulu kwambiri pa zosankha zawo.
Mafoni a CDMA, kumbali inayo, samasinthidwa mosavuta. Onyamula katundu amadziwitse olembetsa ozikidwa pa "azungu," osati SIM makhadi, ndipo mafoni ovomerezeka okha amaloledwa pa intaneti zawo. Mafoni ena a CDMA ali ndi SIM khadi, koma izi ndi cholinga chogwirizanitsa ndi ma LTE kapena kusintha kwa foni pamene foni ikugwiritsidwa ntchito kunja kwa US GSM sikunapezeke m'ma 1990 pamene magetsi ena anasintha kuchokera ku analog kupita ku digito, kotero iwo analowa mu CDMA-panthawiyo, chitukuko chamakono kwambiri cha mafoni.
