I-SMS imele inkonzo yomyalezo omfutshane kwaye isetyenziswe ngokubanzi emhlabeni wonke. Ngonyaka ka-2010, iintetho ze-SMS ezi-6 trillion zithunyelwa , ezilingana ne-193,000 imiyalezo ye-SMS nganye yesibini. (Le nombolo yaphindwa kathathu ukusuka ngo-2007, eyona i-1.8 trillion nje kuphela.) Ngo-2017, iwaka leminyaka yayithumela kwaye ifumana iicatshulwa ezingaba ngu-4 000 nyanga zonke.
Inkonzo ivumela ukuba imilayezo emfutshane ifakwe kwiselfowuni enye iya kwenye okanye kwi-intanethi ukuya kwifowuni. Ezinye izithuthi zesebe zixhasa ukuthumela imiyalezo ye-SMS kwiifowuni zomhlaba , kodwa isebenzisa enye inkonzo phakathi kwezi zibini ukuze isicatshulwa sinokuguqulwa kwizwi ukuze kuthethwe ngefowuni.
I-SMS iqale ngokuxhaswa ngeefowuni ze-GSM ngaphambi kokuba zixhase ezinye iikhompyutha zobuchwephesha ezifana neCDMA ne-Digital AMPS.
Ukuthumela imiyalezo kuncinci kakhulu kwiindawo ezininzi zehlabathi. Enyanisweni, ngo-2015, indleko yokuthumela i-SMS e-Australia yabalwa ukuba yi-$ 0.00016 nje. Nangona ubuninzi bebhanki yefowuni ngokuqhelekileyo yimizuzu yezwi okanye ukusetyenziswa kwedatha, imiyalezo yombhalo ifakwe kwisicwangciso sezwi okanye idibene njengendleko eyongeziweyo.
Nangona kunjalo, ngelixa i-SMS ixabiso elincinci kwisikimu esikhulu sezinto, inokungaphumeleli kwayo, oko kutheni iinkqubo zokuthumela imiyalezo zithandwa kakhulu.
Qaphela: I- SMS idla ngokubizwa ngokuba yombhalo, ukuthumela imiyalezo yombhalo okanye ukuthumela imiyalezo. Kubizwa ngokuba yi- ess-em-ess .
Ziziphi iimida zeSMS Messaging?
Kubaqalayo, imilayezo ye-SMS idinga inkonzo yeseli yeselula, into enokuyikrakra xa ungenayo. Nangona unxibelelwano olupheleleyo lwe-Wi-Fi ekhaya, kwisikolo, okanye kumsebenzi, kodwa akukho nkonzo yeseli, awukwazi ukuthumela umyalezo wombhalo oqhelekileyo.
I-SMS idla ngokuphantsi kweluhlu oluphambili kunezinye izithuthi ezifana nelizwi. Kuye kwaboniswa ukuba malunga ne-1-5 yepesenti yazo zonke iimyalezo ze-SMS zilahlekile ngokwenene nangona akukho nto ibonakala ingalunganga. Le mibuzo iyathembeka yenkonzo ngokubanzi.
Kwakhona, ukongezelela oku kuqinisekisiwe, ezinye iinkqubo ze-SMS azithethi ukuba isicatshulwa sifunde okanye nokuba sinikwe.
Kukho ukukhawulelwa kwabalinganiswa (phakathi kwe-70 no-160) exhomekeke kulwimi lweSMS. Oku kubangelwe kumlinganiselo we-1,120-bit kwi-SMS esemgangathweni. Iilwimi ezinjengesiNgesi, isiFrentshi kunye neSpanish zisebenzisa i- GSM encoding (7 bits / uhlamvu) kwaye ngoko kufinyelela kumda wokulinganisa umlinganiselo kwi-160. Abanye abasebenzisa iikhowudi ze-UTF ezifana nesiTshayina okanye isiJapane zilinganiselwe kwiibali ezingama-70 (isebenzisa ibitshi ezili-16 / uhlamvu)
Ukuba isicatshulwa seSMS sinabantu abangaphezu kwamanqaku afanelekileyo (kubandakanywa izikhala), iyahlukana ibe yimilayezo emininzi xa ifike kummkeli. Imiyalezo ekhompyutheni ye-GSM iyahlukana kwiimpawu ze-153 zamanqaku (ezi-7 ezisetyenzisiweyo ezisetyenziselwa ukwahlula kunye nokwazisa ulwazi). Imiyalezo emide ye-UTF yaphulwa ibe ngamalinganiswa angama-67 (kunye nabalinganiswa abathathu kuphela abasetyenziselwa ukwahlula).
I-MMS , esetyenziswa ngokuphindaphindiweyo ukuthumela imifanekiso, idlulisela i-SMS kwaye ivumela ixesha elide lokuqukethwe.
Iindlela zeSMS kunye nokuDinga kwemiyalezo ye-SMS
Ukulwa nale mingcele kwaye unikeze abasebenzisi ngeempawu ezininzi, iinkonzo ezininzi zokuthumela imiyalezo ziye zadlula iminyaka. Esikhundleni sokuhlawula i-SMS kwaye ubhekane nazo zonke iimeko ezingalunganga, unokukhuphela i-app ezamahala kwifowuni yakho ukuthumela umbhalo, iividiyo, imifanekiso, iifayile kunye nokwenza iifowuni okanye ividyo-fowuni, nokuba unayo iinkonzo zero kwaye usebenzisa nje i-Wi- Fi.
Eminye imizekelo ibandakanya i-WhatsApp, i- Facebook Messenger , ne- Snapchat . Zonke ezi zixhobo azixhaseli kuphela iirisithi ezifundwayo nezifunyenweyo kodwa kunye ne-intanethi yokubiza, imiyalezo engaphuliweyo, imifanekiso kunye namavidiyo.
Ezi zixhobo ziyaziwayo ngoku ngoku ukuba i-Wi-Fi ifumaneka ngokusisiseko nasiphi na isakhiwo. Awunakuxhalaba malunga nokuba nenkonzo yefowuni ekhaya ngenxa yokuba unako ukubhalela abantu abaninzi ngeendlela zeSMS, ngokude nje besetyenzisa insiza.
Ezinye iifowuni zenze ezinye iindlela ze-SMS ezifana neenkonzo ze-iMessage ze-Apple ezithumela iitekisi kwi-intanethi. Isebenza nakwii-iPads kunye ne-iPod ezithintekayo ezingenayo isicwangciso somyalezo weselula.
Qaphela: Khumbula ukuba iinkonzo ezifana nezikhankanywe ngenhla zithumela imiyalezo kwi-intanethi, kwaye ukusebenzisa idatha yeselula ayikhululekile ngaphandle kokuba, ngokuqinisekileyo, unesicwangciso esingenamkhawulo.
Kungathi ngathi i-SMS inokulusebenzisa kuphela ukuthumela imiyalezo ngokulula kunye nomngane, kodwa kukho ezinye iinkalo ezibini apho iSMS ibonakala khona.
Ukuthengisa
Ukuthengiswa kwefowuni kusetyenziswa i-SMS nayo, njengokukhuthaza ukuveliswa kweemveliso ezintsha, iintsebenzo, okanye izakhono ezivela kwinkampani. Impumelelo yayo inokubangela ukuba kulula kangakanani ukufumana nokufunda imilayezo yombhalo, kungenxa yoko kuthengiswa imboni yokuthengisa yesitoreji malunga ne-$ 100 yezigidigidi ngo-2014.
Ulawulo lweMali
Ngamanye amaxesha, ungasebenzisa imilayezo ye-SMS ukuthumela imali kubantu. Kufana nokusebenzisa i-imeyile nge- PayPal kodwa endaweni yoko, uchonga umsebenzisi nge nombolo yefowuni. Omnye umzekelo yiCash Cash .
Ukhuseleko lomyalezo weSMS
I-SMS iphinda isetyenziswe ngamanye amasevisi ekufumaneni iikhowudi zokuqinisekiswa ezimbini . Ezi zikhowudi ezithunyelwa kwifowuni yomsebenzisi xa zicela ukungena kwi-akhawunti yabo yomsebenzisi (njengebhsayithi yabo yebhanki), ukuqinisekisa ukuba umsebenzisi ngubani abo bathi.
I-SMS iqulethe ikhowudi engalindelekanga ukuba umsebenzisi angene kwiphepha lokungena ngephasiwedi ngaphambi kokuba abhalise.
