Iyini i-GPRS nokuthi lokhu buchwepheshe busebenza kanjani?

Esikhathini sethu, ukuthuthukiswa kobuchwepheshe belwazi kuleso simo ukuthi ukutholakala okuhlukahlukene kanye nomthelela wabo oqhubekayo ekuphileni kwethu kwenzeka cishe nsuku zonke. Izolo sasingazi ukuthi iselula iyini, futhi namuhla asiqangi ngisho namahora ambalwa ngaphandle kwalokhu kunoma yimuphi umuntu wanamuhla. Uhlobo luni lwefoni alukwazi ukufinyelela i-Inthanethi namuhla? Wake wake wazibuza ukuthi le-intanethi ye-intanethi isebenza kanjani? Lesi sihloko sizokutshela ukuthi i-GPRS yilaphi nokuthi lokhu buchwepheshe busebenza kanjani.

Igama leGPRS livela enkulumweni ye-English General General Packet Radio Service, engasetshenziswa njengesevisi yedatha yomsakazo wepakethe. Eqinisweni, lobu buchwepheshe buyisisekelo esingaphezu kwezinga lezokuxhumana leselula le-GSM, okuvumela ukudluliswa kwedatha. Ngamanye amazwi, ngenxa yalolu buchwepheshe, ifoni yakho yeselula ingathumela iphinde ithole amaphakethe wedatha kusuka kwamanye amanethiwekhi. Kodwa yini i-GPRS yomsebenzisi ojwayelekile wenethiwekhi yomsebenzisi? Uma uphendula ngokumane, kuyithuba lokuxhuma kwi-intanethi ngqo kusuka kwiselula yakho. Ngesikhathi esifanayo, ijubane lizoba lincane, kodwa izindleko zalesi sevisi zizokujabulisa ngokujabulisayo.

Ake sibone ukuthi i-GPRS ayikho ngokobuchwepheshe, kodwa ngokufinyelela ku-Intanethi. Okokuqala, kuyithuba lokuxhuma kwinethiwekhi kuphi, lapho "ithola" ifoni ephathekayo. Okwesibili, ukukhokhwa kwe-Inthanethi ye-GPRS kwenziwa ngendlela oyikhokhela kuphela ivolumu etholakele futhi idluliselwe yethrafikhi, hhayi ukuhlinzekwa kwensizakalo. Ngakho-ke, lolu hlobo lwe-Intanethi yeselula lungabizwa ngokuthi lungenye yezinto ezifinyeleleka kakhulu ngokubhekwa, futhi mayelana nenqubomgomo yentengo ethembekile.

Esinye isici sokufinyelela okunjalo kwi-intanethi ukuthi ububanzi bendima yevolumu (isivinini nokuzinza kwesiteshi) kuzobekwa yizidingo zobhalisile - uma uxhunyiwe kuphela ukuhlola i-imeyili yakho, isiteshi "sizothola", futhi uma unquma ukulayisha lokho Noma ifayela, ububanzi bendima yevama "kuzothuthuka" kuze kube sezingeni eliphezulu. Futhi isivinini esivunyelwe kakhulu sendlela enjalo yokuxhumana kule mbono ifinyelela ku-171.2 Kbps. Ngokwenzayo, lesi sibalo singaba umyalo wokuphakama okuncane futhi kuncike eziningana zezici, isibonelo, ikhwalithi yokufaka endaweni enikeziwe kanye nemishini yomqhubi ohlinzeka ngale nsizakalo. Ngokwesilinganiso, i-GPRS "yasekhaya", isivinini sayo asidluli ku-100.0 Kbps, siyobiza umsebenzisi umyalelo wezinga eliphansi eshibhile kunanoma iyiphi enye indlela yokufinyelela kwi-intanethi.

Ku-opharetha wamanethiwekhi weselula, lolu hlobo lokudluliswa kwedatha lunezinzuzo eziningana ezingenakuphikwa ngaphezu kwabancintisana. Lesi isisindo esisheshayo, futhi isethaphu esilula futhi esheshayo, nomthwalo omncane wemishini, ngisho "nokuxhumeka" okuqhubekayo okuvela kumsebenzisi. Ngaphezu kwalokho, opharetha angabeka inani lokukhokha, elisuselwe kokubili kolwazi oludluliselwayo nasesikhathini "somuntu on-line" somsebenzisi. Izinzuzo kubathengi bale nkonzo nazo ziyabonakala - izindleko ezincane ezihlanganiswe nekhwalithi kanye nokuxhumeka ngisho nasezindaweni ezikude zivumela umbhalisi ukuba abe nokufinyelela okuqhubekayo kwemeyili, ukulandwa nokuthumela amafayela ahlukahlukene futhi ahlanganyele nokuhweba kwe-intanethi.

Njengoba uthola ulwazi oluvela kulesi sihloko mayelana nokuthi yi-GPRS, ungakhohlwa ukuthi ubuchwepheshe abuyimi. Emadolobheni amakhulu, le ndlela yokudluliswa kwedatha ishintshwa kancane kancane nge-3G kanye ne-Wi-Fi ngokushesha, futhi "esifundazweni" izinga eliphezulu lokudlulisa idatha ngosizo lwamanethiwekhi weselula lunyuke kakhulu ngenxa yokusetshenziswa kobuchwepheshe be-EDGE. Kodwa, noma kunjalo, i-GPRS isendleleni ethandwa kakhulu yokudluliswa kwedatha ezindaweni eziningi zeSoviet Union yangaphambili.
