Uva malunga 'nokuthunyelwa kwefowuni' njengendlela yokuphucula ukukhuphela kwakho kunye nomdlalo wezantya, kodwa yintoni na ukuhanjiswa kweefama?
Ukuthunyelwa kweePort kuhanjiswa kweempawu zekhompyutha ukulandela iindlela ezithile zekhompyutheni kwikhompyutha yakho. Ukuba umqondiso wekhompyutha ungayifumana indlela yayo kwikhompyutheni i-millisecond embalwa, iyakongeza ukuze ibe yenyuka ngokukhawuleza kwinqanaba lakho okanye ukukhuphela.
Iindlela ezingama-65,536 zokukhetha: ikhefu yomnatha womnatha (okanye i - adapter yenethiwekhi engenantambo) ngasemva kwekhompyutheni yakho inemizila engama-65,536 microscopic ngaphakathi kwayo. Intambo yenethiwekhi yakho ifana nomgwaqo omkhulu, ngaphandle kwekhefu yakho yenethwekhi ineendlela ezingama-65,536, kwaye kukho i-tollboth kwicala ngalinye. Sibiza umnqweno ngalunye 'ichwethi'.
Isalathisi sakho se-intanethi sinezigidi zeemoto ezincinci ezihamba kule mizila engama-65,536. Sithi la mavili amancinci "thumela iipakethi". Iipakethi zokudlulisa iikhompyutha zingahamba ngokukhawuleza (ukuya kumawaka eekhilomitha ngomzuzwana), kodwa zigcina imigaqo ye-stop-and-go, apho kufuneka ukuba ayeke kwi-intersection enkulu yenethiwekhi njengokungathi umda owela phakathi amazwe.
Kwinqanaba ngalinye, ipakethi kufuneka yenze izinto ezintathu:
- Fumana i-port evulekile,
- Phinda uvavanyo lokuchonga oluya kuluvumela ukuba luhambe kulolu hlobo, kwaye ukuba akunjalo,
- Hambisa kwisibuko esilandelayo uze uzame kwakhona, ade avunyelwe ukudlula kwi-toll.
Kwezinye iimeko, iipakethi ezithunyelwe ngabacuki ziya kubanjwa kwaye zigcinwe kwintlambo, apho ziya kuthi zichithwe kwii-electron ezingenanto. Xa oko kwenzeka, kuthiwa " ukupakisha kwepakethe " okanye "ipakethe yokumisa".
Ziziphi iiports IiPakethe zekhompyutha ezifana nokuSebenzisa?
Zonke iifayili kwikhompyutheni yakho ngokuqhelekileyo zicwangciselwe ukuthumela iipakethi zayo kwi-port ethile. Ezi zikhetho zokufowunjwa zihlala ziqulunqwe njengemigangatho yenkqubo kwinkampani yekhompyutha. Ngako oko, i-router yakho kufuneka iyalwe ukuba ivumele iipakethe ngokusebenzisa ezi zibuko, hleze unganciphise isivinini apho batshintshela kuwo / kwiikhompyutheni yakho:
- Amaphepha e-HTML: i-port 80
- Ifayile yeFTP idlulisela: i-port 21
- World of Warcraft: isango 3724
- I-imeyile ye-POP3: port 110
- I-MSN Messenger : i-port 6901 kunye namachwep 6891-6900
- Kuze kubekho: i-port 1024
- Iibhulozo zeBit: i-port 6881
Ngoko Kwenzeka njani & # 39; Ukuhanjiswa kwePort & # 39; Ingxaki Kulo?
Ukuthunyelwa kweePort xa uyala umzila wakho wenethwekhi ukuze uchonge kwaye uphinde uthumele iipakethi nganye ukuhamba ngeendlela ezithile ze-elektroniki. Esikhundleni sokuba zonke iipakethe ziyeke kwichweba ngalinye lize lifumane i-port evulekile, i-router inokucwangciswa ukukhawulezisa inkqubo ngokuchonga nokuhambisa iipakethi ngaphandle kokubayeka kwichweba ngalinye. I-router yakho isebenza njengoluhlobo lwepolisa elihamba ngokukhawuleza lendlela elawula i-traffic phambi kwe-tobobos.
Nangona ukuchongwa kwekhompyutha kunye nokuthunyelwa kuthatha kuphela i-millisecond, ixesha elibandakanyekayo longeza ngokukhawuleza njengoko izigidi zeepakethe ze-elektroniki zingena kwaye zishiye ikhompyutha yakho ye-intanethi. Ukuba ukhetha ukuthunyelwa kwefowuni yakho ngokuchanekileyo, unokukhawulezisa i-intanethi yakho ngeemitha ezimbalwa. Kwimeko yokukhuphela iifayile ezinkulu, njengokwabelana nge- P2P , usenokuzigcina ixesha leexesha lokukhuphela ngokucwangcisa i-port yakho phambili. Ingoma eyayisetyenziswe ukuthatha iiyure ezingama-3 ukukhuphela ngoku ingagqiba ngaphantsi kwemizuzu engama-10 ukuba i-port yakho phambili iya kusetyenziswa ngokuchanekileyo.
Ndingayifunda njani indlela yokuLungiselela iRotter yam & # 39;
Nangona iprogram yokudluliselwa kwefama ingaba yinkwantya, kukho izifundo kwi-intanethi enokukunceda ngokuqinisekileyo abaqalayo. Isizathu esona siqhelo sokwenza iiprogram ukuthumela phambili kukuphucula ukukhawuleza kokulandelwa kwe- BitTorrent , kulandelwa kukuphucula ukusebenza kweekhompyutheni kunye neendaba zokusakaza . Kuzo ziphelo, kukho ubuchule obuhle kakhulu ngabantu kwi-www.portforward.com. Ukukhawulezisa umsebenzisi wakho wokukhuphela, umdlalo, okanye inkqubo yesofthiwe: funda igama elichanekileyo lomsebenzisi wakho kunye nesofthiwe yakho, uze u tyelele eli phepha ukuze ufundise indlela ebonisa ngayo indlela umzila wakho owenza ngayo imiyalelo yokudlulisela izibuko.
