Kwi-intanethi ye-intanethi, ukunyanzelwa kwemali kukulahlekelwa kwamandla omnxeba wokunxibelelana okulinganiswe kwi- decibels (dB) . Enye yeendlela ezisetyenziselwa ukwandisa amandla okubonisa uphawu ukukhusela ukukhutshwa kwamandla okukhupha .
Ukunwa
Ukulinda kwenzeka kwiinkcukacha zekhompuyutha ngezizathu ezininzi:
- uluhlu - zombini ukungena kwentambo kunye nokuhanjiswa ngentshontsho ngokukhawuleza kwehla ngamandla ekugqibeleni
- ukuphazamiseka - kwiintanethi ezingenazintambo, ukuphazamiseka kwomsakazo okanye ukuphazamiseka ngokomzimba njengeendonga kwanokunciphisa imiqondiso yokunxibelelana
- Ubungakanani befowuni - kwiinkanki zentambo, iingcingo ezincitshisiweyo zithwele ukugqithiswa okuphezulu (ngaphezulu) kuneentambo ezinamandla
Kwiinkonzo ze- DSL , amanyathelo okunciphisa umgca umqondiso welahleko phakathi kwekhaya kunye ne-DSL yokufikelela kwenkxaso-mali (ukutshintshiselana phakathi). Ukulumka kubaluleke ngakumbi kwiinkonzo ze-DSL njengoko ixabiso leedolophu umzi onikezelweyo unokufumana umqobo xa umgangatho wokunciphisa umgca ukhulu kakhulu. Iimpawu eziqhelekileyo zokunciphisa umgca kwi-DSL uqhagamshelo ziphakathi kwe-5 dB ne-50 dB (ixabiso elincinci kangcono). Ezinye iibartshi zokubambisa zibonisa ixabiso lokunciphisa umgca kumaphepha abo ekhonsoli, nangona bahlala benomdla kuphela kubaphathi beekhredithi eziphambili xa iingxaki zokuxhamla iingxaki
I-Wi-Fi isekela into ebizwa ngokuba yi- dynamic rate scaling eguqulela ngokuzenzekelayo izinga lokufikelela kwedatha yokuxhuma okanye ukuhla ngokunyuka okuthe ngqo ngokuxhomekeke kumgangatho wokuthumela umgca. Kwiinkalo eziphezulu zokulinda, uxhumano lwe-54 Mbps lunokungena kwizinga eliphantsi njenge-6 Mbps, umzekelo.
Igama elithi "ukulinda" ngamanye amaxesha lisebenza kwezinye iimeko ngaphandle kwamanethiwekhi ekhompyutha. Ngokomzekelo, i-audiophiles kunye nabaxhasi bezandi abazisebenzisayo bangasebenzisa ubuchule bokunqanda ukulawula amanqanaba omsindo xa bexubanisa imiyalezo eyahlukeneyo yomsindo kunye.
Ukugqitywa kweMfuno
Ukugqitywa kwembonakalo kusebenza ngokuchasene nesigxina sesigxina, ukwandisa ugesi ngamandla omqondiso womgca ngeyiphi na yezindlela ezininzi zobugcisa. Iifom ezahlukeneyo zokukhulisa zivelise ingxolo engaphezulu okanye engaphantsi kwimiqondiso. Kwiinkcukacha zekhompyutheni, ukukhulisa ngokuqhelekileyo kufaka ingcamango yokunciphisa ingxolo ukuqinisekisa ukuba idatha yesigidimi esingaphantsi ingonakali kwinkqubo.
Izixhobo zokuphindaphinda kwenethiwekhi zihlanganisa ngokubanzi umbane wesikhangiso kwiisekethe zabo. Umphindaphindi usebenza njengomphakathi phakathi kokugqibela kwemiyalezo yomyalezo. Ifumana idatha evela kumthumeli wangaphambili (okanye enye i-repeater backstater), yenze inkqubo ngokusebenzisa i-amplifier, ize idlulisele uphawu olomeleleyo phambili ekuya kuyo.
Okubizwa ngokuba yi- signal boosters kunceda ukukhulisa iimpawu ezingenawaya. Ngaphandle kweziphinda, i-antenna kunye nolunye uphuculo lwe-antenna lusebenza kakuhle.
Ingcamango ehlukileyo ukusuka kumqondiso wokukhulisa, ukuphuculwa kwe- DNS yintlobo ye- Distributed Denial of Service (DDoS) ekuhlaselweni apho umhlaseli onobungozi okanye i- botnet isebenzisa i- Domain Name System (DNS) ukukhukula umncedisi wesigxina ngesigidimi somyalezo. Amplification, kulo mzekelo, ibhekisela ekuziphatheni kwe-DNS ekuphenduleni imiyalezo emincinci yokucela ngokuthumela ixabiso elikhulu leempendulo.
Ixesha eliphakanyisiweyo lokuzimela (ukuhlukaniswa kwimiqondiso yesibini kunye ne-DNS amplification) ibhekisela kwingcamango ephambili ekukhuselekeni kwenethiwekhi yecomputer kunye neenkcukacha zengcaciso apho imibutho emibini isebenze kunye ukuze ilandele ixabiso lekhibhodi eyimfihlo.
