Imiyalo ye-NSLookUp namagama e-DNS kumongo wokuthuthukiswa kwe-intanethi

Amakhompiyutha, njengabantu, kuqala kokuwodwa, bese kuhlelo. Ngokungangabazeki, lo muntu udala uhlelo lwekhompiyutha (inethiwekhi), kodwa ngezizukulwane zongcweti lolu hlelo (inethiwekhi) "ngokwayo lusebenta" inqubo yentuthuko yayo. Lokhu kulandela ukuthuthukiswa kwangempela kwesikhala se-intanethi kanye nendima edlalwa kuyo ngokubaluleka kwamagama e-DNS.

Ithimba le-NSLookUp: incazelo yamathuba, umphumela wendlela yekhompuyutha eyodwa kuya esikhaleni se-Inthanethi, ochwepheshe ezweni lokudala amathuluzi okusabalalisa ulwazi lokucubungula ulwazi, kanye nabasebenzisi - ekuqondeni ukuthi izinto zisebenza kanjani ngokoqobo.

Umlando wokuqala: amanethiwekhi alula

Izwe le-intanethi lakhiwa "yedwa", nakuba kungenakwenzeka ukuphika indima ebalulekile yababili ngabanye kanye namaqembu okuthuthukiswa afanelekayo. Kodwa uma inani lifika emgangathweni, izindima zivame ukushintsha. Ikhompiyutha ayitholakali ukuhlakanipha, futhi isihloko se-intelligence yokufakelwa isikhathi eside sasijwayele ukungajabulisi: ngokuba umuntu omude akuwona kuphela futhi uphawu oluyinhloko nenjini yentuthuko.

Ukudalwa kwezandla zabantu akugcini nje "baphile" impilo yabo siqu ngokusebenzisa isikhala nesikhathi, kodwa futhi "benza" impembelelo embi emisebenzini yezizukulwane ezintsha zongcweti.

Ukuhlanganiswa kwamakhompyutha enethiwekhi kuvele ngokwemvelo. Ochwepheshe basheshe baqonda. Abasebenzisi basetshenziselwa ukusebenza eqenjini lapho izenzo kwikhompyutha eyodwa ziholela ekushintsheni kwenye into. Inhlangano yenethiwekhi yezakhi kanye nezinqubo ithole isicelo sayo cishe kuzo zonke izindawo futhi ijwayele.

Ukuqaphela kwaba ngokoqobo, izinqubo ezihlukahlukene zenethiwekhi zaba nemvelo futhi zilula, futhi amakhompiyutha "afunde" ukuba "axoxisane" nabo.

Amanethiwekhi ahlukanisiwe

Kusukela ekuzalweni kwenethiwekhi, ubuso be-sphere yolwazi lushintshile masinyane, kodwa kusekude nokuhlela. Izibonelo zenethiwekhi ezibonakalayo nezingokoqobo ziye zaba yinto evamile, kodwa kwakungakafiki i-inthanethi, kwakungakafiki uhlelo lwe-Inthanethi.

Ukudalwa kwezinhlelo zokuqeqesha ezenza umsebenzi wekhompiyutha amaningana wokufundisa abafundi, ngisho nasemakilasini ahlukene / izakhiwo, kwakuhlukile futhi kubalulekile ngesikhathi sokudalwa kwayo.

Ukuzenzakalela inqubo yokukhiqiza okuthile, ukuhlanganisa izinqwaba zezingosi, izinqubo, abahlinzeki, abathengi nakho kwakuyimpumelelo ebalulekile futhi edingekayo kodwa "yiminithi".

Noma yiziphi ezinye izinhlelo zokusebenza zenethiwekhi zazihlukile futhi zithakazelisayo ngesikhathi sokuthuthukiswa, ukuqaliswa nokuthunyelwa, bese zijwayele ukujwayele futhi zijwayele. Umthengi ngokushesha ukhohlwa indlela ayephila ngayo ngaphambi kokusetshenziswa kwesicelo senethiwekhi ethile.

I-NSLookUp - umphumela wokuqala noma indlela yomqondo wenethiwekhi

, ей принадлежит знатная роль в информационной сфере. Kumele sikhokhele ku- Windows , inendima ebalulekile enkambu yolwazi. Kodwa akuyona isiqinisekiso sokuthi bekukhona ukuthi i-NSLookUp engabonakali ivele. Umqondo omuhle futhi umndeni wakwa Unixids ungakhipha umnikelo wabo ekuzalweni kwawo. Imithetho yokusebenza kwinethiwekhi iyadingeka, kodwa iningi lawo lingabonakali, nakuba liphawuleka kakhulu. I-NSLookUp ivele ku-Windows NT nakwezinhlelo ezifanayo, nakwamanye amapulatifomu.

Abaphathi benethiwekhi nabathuthukisi bezinhlelo, leli qembu linikeza amathuba alula. Empeleni kuwuhlobo lomsebenzi we-DNS-iklayenti (ikakhulukazi elula ku-NSLookUp online) futhi ivumela ukuhlolisisa izinkinga zokuxazulula amagama ngokuzenzekelayo. Lona umphumela wokuthuthukiswa kwamanethiwekhi. Mhlawumbe, umqondo wokusabalalisa amaseva we-DNS uzoba nokuqukethwe okuhlukile kanye nenhlangano esikhathini esizayo, kodwa okwamanje, usebenzisa imiyalo ye-NSLookUp, ungathola ulwazi oluqondile nolwalufanelekile, kokubili ukusetshenziswa kokusebenza kanye nokunquma izinkinga ezithile.

Kubalulekile ukuqonda ukuthi ukuthuthukiswa kobuchwepheshe benethiwekhi, ekugcineni, bekugxilwe ekulandeni okuthile kwezinhlelo, inhlanganisela yamapulatifomu ahlukahlukene e-computing, izinhlelo nezinqubo eziqinisekisiwe. Futhi akudingeki ukuthi ube nomqondo ophelele walokho okuzoba ngumsebenzisi othembekile, unjiniyela noma umlawuli. Ezimweni eziningi kunokwanele ukuba nomqondo walokho okushiwo yi-NSLookUp.

Izimpawu nokukhomba kwabo

Iyini inkatho yabaphathi nabathuthukisi, imiyalo ye-NSLookUp inikezwa kumsebenzisi ojwayelekile ngendlela elula futhi efinyeleleka. этого инструмента, пользователь получит точное представление о том, что такое домен, DNS, IP, A, AAAA, Refresh, TTL и пр.
