Ngakolunye uhlangothi, ukugcinwa kwayo kwaziwa njengokumba eqolo, njengoba izingxenye eziyisipele ezidingwa yila madivayisi zikhethekile futhi kunzima ukuzithola emakethe yendabuko kanye namawebhusayithi.
Enye yezandulela ezinkulu zeSatellite Technology kanye nokusetshenziswa kwe-Outernet, ingaphezulu futhi ayilutho ngaphansi kwe-"National Aeronautics and Space Administration" noma "NASA" emazingeni ayo okuqala asungulwe ngolimi lwesiNgisi, okungamandla okuphatha. wase-United States of America, engomunye wabanikazi abaningi bamasathelayithi atholakala ku-Earth orbit. Ngokunjalo, le nhlangano enkulu namasathelayithi ayo isiza izifunda eziningi zomhlaba ukuthi zihlale zixhumeke kuWebhu.
Ukufakwa Nokuqashwa
Ukufakwa kwemishini ye-Satellite Technology ukuze isetshenziswe ekhaya, kunenqubo elula neyingqayizivele engenziwa yinoma yiluphi uhlobo lomuntu ngendaba yemizuzu, kodwa kukhona ochwepheshe abanezitifiketi eziqinisekisa lowo muntu, ukufeza ukufakwa kusho idivayisi, lezi kuyizo ezikhonjiswe ukwenza inqubo eshiwo ngaphandle kwenkinga. Kodwa-ke, umsebenzisi angakwazi ukwenza inqubo yokufaka ngokwakhe, ecabangela ukuthi izindleko zokuqasha ziphezulu futhi ziyakhuphuka ngokufaka.
Uma la madivayisi eqashwa, anezinhlobo ezimbili zokukhokha ezaziwa ngokuthi "Prepaid" kanye "Ne-Postpaid", ezisiza abasebenzisi bakhokhele isevisi ngezindlela ezihlukene, njalo beqinisekisa imodeli yokukhokha abayifunayo kunkontileka yokuqasha isevisi. sebenzisa, ngaleyo ndlela bagweme izinkinga zomthetho noma zokubalwa kwezimali ngenxa yokubambezeleka kokukhokhwa kwensizakalo eshiwo ngesikhathi esilinganisiwe. Kodwa-ke, bonke abasebenzisi abakhansela isevisi, okuholela ekusetshenzisweni kwesevisi, kufanele balethe amadivayisi aqashiwe ngokushesha nangokungaguquki.
Ukubaluleka Kobuchwepheshe Besathelayithi
Lolu hlobo lobuchwepheshe njengamanje lusezingeni eliphezulu lokuhlobana emhlabeni, okuyilona olusetshenziswa kakhulu ekwakhiweni kwama-Smartphones amaningi, amathelevishini, amamodemu, amarutha, phakathi kwamanye amadivaysi, asebenzisa Ubuchwepheshe Besathelayithi ekusebenzeni kwawo ngempumelelo.Ngaphezu kwalokho, lobu buchwepheshe ivumela ukuxhumana okuwuketshezi futhi idatha ethunyelwe ifinyelela lapho iya khona ngokushesha, ngaleyo ndlela ivumela abantu ukuthi bahlale bexhumekile. Ngokunjalo, wonke umsebenzisi uzokwazi ukujabulela ukuphequlula iwebhu okuzinzile esebenzisa lobu buchwepheshe obusha obuhle kakhulu.
Ngithanda ukufunda ngemibono eyisisekelo ye-"Soft Technology" eyinkimbinkimbi futhi emisha, kanye nezimfanelo zayo zobuchwepheshe nezici ezikhethekile, uma kunjalo, ngifike endaweni efanele, njengoba sinesihloko esiphelele kuwe, okokuqala- ulwazi ngesandla kanye neqiniso mayelana nalesi sihloko, ongase uthandeke kanye nentshisekelo yakho, ukuze uqonde kangcono lolu hlobo olukhulu lobuchwepheshe oluletha izinguquko emhlabeni, sikumema ngokufudumele ukuthi udlule, ujabulele futhi ufunde isihloko sethu esihle kakhulu. : Ubuchwepheshe Obuthambile.
