I-SMS imelela inkonzo emfushane yomlayezo futhi isetshenziswe ngokugcwele emhlabeni jikelele. Ngonyaka ka-2010, izincwadi ezingaphezu kuka-6 trillion ze-SMS zithunyelwe , okulingana nemilayezo ye-SMS engu-193,000 njalo. (Leli nani laphindwe kathathu kusukela ngo-2007, okwakuboniswa nje ngo-1.8 trillion.) Ngo-2017, izinkulungwane zeminyaka kuphela zithumela futhi zithola amatheksthi angaba ngu-4 000 njalo ngenyanga.
Insizakalo ivumela imiyalezo emifushane ukuthi ithunyelwe kusuka kwelinye ucingo ukuya kwelinye noma kusukela e-intanethi kuya kumakhalekhukhwini. Abanye abathwali beselula baxhasa ngisho nokuthumela imilayezo ye-SMS kumafoni wezwe , kodwa lokho kusebentisa enye insizakalo phakathi kokubili ukuze umbhalo uguquke ukuze ukhulume ngefoni.
I-SMS yaqala ngokusekela amafoni we-GSM ngaphambi kokusekela kamuva ubuchwepheshe obunjenge- CDMA ne-AMPS ye-Digital.
Ukuthumela imiyalezo kuncane kakhulu ezingxenyeni eziningi zomhlaba. Eqinisweni, ngo-2015, izindleko zokuthumela i-SMS e-Australia zibalwa ukuba zibe ngu-$ 0.00016 kuphela. Ngenkathi inqwaba ye-bill cell phone ngokuvamile yimizuzu yayo yezwi noma ukusetshenziswa kwedatha, imiyalezo yombhalo ifakwe ohlelweni lwezwi noma ifakwe njengendleko eyengeziwe.
Kodwa-ke, ngenkathi i-SMS ishibhile kakhulu ohlelweni olukhulu lwezinto, lunezinkinga zalo, yingakho izinhlelo zokusebenza zokuthumela imiyalezo zithandwa kakhulu.
Qaphela: I- SMS ivame ukubizwa ngokuthi ukuthumela imiyalezo, ukuthumela imiyalezo noma ukuthumela imiyalezo. Kubizwa ngokuthi i- ess-em-ess .
Yiziphi Izilinganiso ze-SMS Imilayezo?
Okokuqala, imilayezo ye-SMS idinga isevisi yocingo, okungabacasula ngempela uma ungenakho. Ngisho noma uxhumano olugcwele lwe- Wi-Fi ekhaya, esikoleni, noma emsebenzini, kodwa akukho service yeseli, awukwazi ukuthumela umlayezo wombhalo ovamile.
I-SMS ivame ukwehliswa ohlwini olubalulekile kunezinye izimoto ezifana nezwi. Kuye kwaboniswa ukuthi cishe amaphesenti angu-1-5 yawo yonke imilayezo ye-SMS empeleni ilahlekile ngisho noma kungabonakali lutho. Le mibuzo ukuthembeka kwensizakalo yonkana.
Futhi, ukwengeza kulokhu kungaqiniseki, ezinye ukuqaliswa kwe-SMS azibi ukuthi ngabe umbhalo ufundwa noma ngisho nalapho uhanjiswa.
Kunomkhawulo wabalingiswa (phakathi kuka-70 no-160) okuxhomeke olimini lwe-SMS. Lokhu kubangelwa ukulinganiselwa okungu-1,120-bit esimisweni se-SMS. Izilimi ezinjengesiNgisi, isiFulentshi neSpanishi zisebenzisa i- GSM encoding (7 bits / uhlamvu) ngakho-ke kufinyelela kumkhawulo womlingiswa wama-max ku-160. Abanye abasebenzisa izikhombisi ze-UTF ezifana nesiShayina noma isiJapane zikhawulelwe ezinhlamvu ezingu-70 (isebenzisa amabhuzu ayi-16 / uhlamvu)
Uma umbhalo we-SMS unezinhlamvu ezingavumelekile (kufaka phakathi izikhala), uhlukaniswe waba yimilayezo eminingi uma ufinyelela kumamukeli. Imilayezo ekhonjiwe ye-GSM ihlukaniswe kumathwathi wezinhlamvu ezingu-153 (izinhlamvu eziyisikhombisa ezisele zisetshenziselwa ukuhlukaniswa kanye nokwazisa imininingwane). Imilayezo ye-UTF ende iphulwe zibe yizinhlamvu ezingu-67 (ezinamahlamvu amathathu kuphela asetshenziselwa ukuhlukanisa).
I-MMS , evame ukusetshenziselwa ukuthumela izithombe, idlulisela i-SMS futhi ivumela ubude obude bokuqukethwe.
Izindlela ze-SMS kanye nokudinga imiyalezo ye-SMS
Ukulwa nale mikhawulo futhi unikeze abasebenzisi ngezici eziningi, izinhlelo eziningi zokuthumela imiyalezo ziye zavela eminyakeni edlule. Esikhundleni sokukhokha i-SMS futhi ubhekene nazo zonke izinkinga zayo, ungalanda uhlelo lokusebenza lwamahhala efonini yakho ukuthumela umbhalo, amavidiyo, izithombe, amafayela nokwenza amakholi noma amavidiyo, ngisho noma unezinsizakalo zero futhi usebenzisa nje i-Wi- Fi.
Ezinye izibonelo zifaka ukuthi WhatsApp, Facebook Messenger , no- Snapchat . Zonke lezi zinhlelo zokusebenza azisekeli kuphela amaresidi okufunda nokudilizwa kodwa futhi nokushaya kwe-intanethi, imiyalezo engaqhekeki zibe yizicucu, izithombe namavidiyo.
Lezi zinhlelo zokusebenza ziyaziwa kakhulu manje ukuthi i-Wi-Fi iyatholakala ngokuyisisekelo noma yisiphi isakhiwo. Akudingeki ukhathazeke ngokuthi unomsebenzi wamaseli ekhaya ngoba usengabhala abantu abaningi ngalezi zindlela ze-SMS, uma nje zisebenzisa lolu hlelo lokusebenza.
Amanye amafoni akhethe ezinye izindlela ze-SMS ezifana ne-Apple iMessage service ethunyelwa imibhalo phezu kwe-intanethi. Isebenza ngisho naku-iPads ne-iPod okuthinta okungenayo uhlelo lomlayezo weselula nhlobo.
Qaphela: Khumbula ukuthi izinhlelo zokusebenza ezinjengezikhulunywe ngenhla zithumela imilayezo phezu kwe-intanethi, futhi ukusebenzisa idatha yeselula akuyona mahhala ngaphandle kokuthi, ngempela, unelungiselelo elingenamkhawulo.
Kungase kubonakale sengathi i-SMS iwusizo kuphela ekuthumeleni imiyalezo elula emuva nangomngane, kodwa kunezinye izindawo ezimbalwa lapho i-SMS ibonakala khona.
Ukuthengisa
Ukumaketha kwamaselula kusebenzisa i-SMS futhi, njengokukhuthaza imikhiqizo emisha, amadili, noma izinkampani ezivela enkampanini. Ukuphumelela kwayo kunganikezwa ukuthi kulula kanjani ukuthola nokufunda imiyalezo, ngakho-ke imboni yokukhangisa yeselula kuthiwa ifaneleke ukuhamba nge $ 100 billion kusukela ngo-2014.
Ukuphathwa Kwemali
Ngezinye izikhathi, ungasebenzisa ngisho nemilayezo ye-SMS ukuthumela imali kubantu. Kufana nokusebenzisa i-imeyili nge- PayPal kodwa kunalokho, kubonisa umsebenzisi ngenombolo yocingo yabo. Isibonelo esisodwa yi- Square Cash .
