Uma kuqhathaniswa nokusebenza kwe-intanethi yesevisi ye-intanethi, isivinini se-DSL siye sahamba kancane kancane ngokomlando. Noma kunjalo, ijubane le-DSL Internet liyanda njengoba ubuchwepheshe buthuthukisa futhi abahlinzeki bezinsizakalo bathuthukisa ingqalasizinda yabo yenethiwekhi. Ijubane eliqondile le-DSL oyolijabulela liyahlukahluka kuye ngezici eziningana. Kulula kangakanani-ke i-DSL?
Abahlinzeki bezinsizakalo bathengisa isivinini se-DSL ngokulinganisa kwe- bandwidth . Izinombolo zomkhawulokudonsa zikhangiswe ukuhlinzeka ngosizo lwe-DSL yokuhlala kusuka ku-128 Kbps kuya ku-3 Mbps (3000 Kbps).
Ngenxa yokuthi izilinganiso ze-DSL ngesivinini ziyahlukahluka kakhulu, kungcono ukuhlola kuqala nomhlinzeki wakho wesevisi ukuze unqume amazinga omkhawulokudonsa ehambisana nokubhalisa kwakho. Abanikezeli abaningi banikeza ukukhetha kwezinsizakalo ze-DSL ngezilinganiso ezahlukene zokuhamba komkhawulokudonsa.
Isivinini se-DSL sokulanda nokulayisha
Isivinini sakho se-DSL singashintsha kuye ngokuthi usebenzisa kanjani inethiwekhi.
Abanikeli be-DSL bavame ukukhangisa ngesivinini senkonzo yabo besebenzisa inhlanganisela yezinombolo ezimbili ze-bandwidth; isibonelo, "1.5 Mbps / 128 Kbps."
Inombolo yokuqala, 1.5 Mbps kulokhu, ibhekisela kumkhawulokudonsa ophezulu wokutholakala kokulandwayo. Izibonelo zemisebenzi yokulanda inethiwekhi zihlanganisa ukuphequlula amawebhusayithi, ukuthola amafayela kusuka kumanethiwekhi e- P2P , nokwamukela ama-imeyili.
Inombolo yesibili, i-128 Kbps kulesi simo, ihambisana nomkhawulokudonsa otholakala ukulayishwa. Isibonelo semisebenzi yokulayishwa kwenethiwekhi ihlanganisa ukushicilela kumawebhusayithi, ukuthumela amafayela phezu kwenethiwekhi ye-P2P, nokuthumela ama-imeyili.
Izinsizakalo ze-DSL zokuhlala zivame ukuhlinzeka nge-bandwidth ephakeme ngokulandwayo kunokulayisha, njengoba amakhasimende amaningi achitha isikhathi esiningi kwimisebenzi yokulanda inethiwekhi. Lezi zikhathi ezithile zibizwa ngokuthi amasevisi e-DSL (ADSL) asymmetric. Ku-ADSL, inamba yokuqala ye-bandwidth izoba ngaphezulu kakhulu kuneyesibili njengokwesibonelo ngenhla. Nge-DSL ehambisanayo (i-SDSL), zombili izinombolo zizofana. Izinsizakalo eziningi ze-DSL zamabhizinisi zisebenzisa i-SDSL, njengoba amakhasimende ebhizinisi ngokuvamile achitha isikhathi esiningi sokulayisha phezu kwamanethiwekhi abo.
Ukuhluka kwe-DSL Ukushayisana Phakathi Kwezindlu
I-bandwidth ephezulu elinganisiwe yokuxhumeka kwe-DSL ngokuvamile ayikwazi ukufinyelelwa. Ukwengeza, ukuvinjelwa kwangempela kwe-DSL kuhluke phakathi kwemindeni. Izinto ezithinta isivinini se-DSL zihlanganisa:
- Ikhwalithi yomugqa wefoni lapho uhlala khona. Izakhamuzi ezinamathebhu okubhebhethekisa kangcono zingaphumelela ngesivinini esisheshayo se-DSL.
- Ubude bomugqa wocingo phakathi kwezindlu kanye nehabhu lenkampani yenkampani (evame ukubizwa ngokuthi "ihhovisi eliphakathi"). Ubuchwepheshe be-DSL "bubucayi obude" ngoba ukusebenza kwayo kunciphisa kakhulu njengoba uthola kude nakakhulu kule ndawo.
- I-glitches yesevisi. Ngenkathi kuvamise ukuvinjelwa njalo, i-DSL ijubane ngokungazelelwe uma umnikezeli wesevisi enenkinga yobuchwepheshe ngenethiwekhi yabo. Izinga kufanele zibuyele evamile ngemuva kwemizuzu embalwa noma amahora.
Ngokunciphisa ukuhlala kwabo, amakhasimende angenzi lutho ngokushintsha lezi zici. Ezinye izici ongazilawula ngokuqondile zihlanganisa:
- I-Spyware kumakhompyutha (ama). Ngisho nalapho inethiwekhi ye-DSL ingase isebenze ngesivinini esigcwele, izinhlelo ze-spyware zingadla umkhawulokudonsa, ziphanga isivinini sakho se-DSL. Izinhlelo zokulwa ne-spyware kufanele zisebenze njalo kumanethiwekhi ukuvimbela le nkinga.
- Izingcingo ezingenasici noma i-wireless router . Ama-routers ahlala phakathi kwamakhompyutha akho nokuxhumeka kwe-inthanethi. Uma kungasebenzi kahle, i-router ingaba kakhulu ukukhawulela isivinini se-DSL esitholakala kuwo wonke amakhompyutha. Ukuxhuma ikhompyutha ngqo kwi-intanethi kungasiza ukuxilonga lesi simo.
- Ukuxhumeka kwenethiwekhi okungenazintambo. Ezimweni ezimbi kakhulu, uxhumano lwe-Wi-Fi olude kakhulu phakathi kwekhompyutha kanye nenethiwekhi yocingo elingenantambo ngeke luhambisane ijubane loxhumano lwe-DSL Inthanethi. Ukuthuthukisa ikhwalithi yokuxhumeka kwe-Wi-Fi kuzoxazulula le nkinga.
- Ama-computer (ama) amadala. Amakhompyutha amadala kakhulu aswele amandla okucubungula okwanele noma imemori ayikwazi ukugcina ijubane ngokuxhuma okuphezulu kwe-DSL. Ungaqinisekisa le nkinga ngokuqhathanisa isivinini se-DSL phakathi kwamakhompyutha endaweni yokuhlala.
