Token - Iyini?

Imininingwane bekulokhu kuyingxenye ebalulekile yomsebenzi womuntu. Ezinye izinhlobo zawo ke kwakuthé chithi saka, kuyilapho ezinye uvinjelwe. Sekube izindlela ukufihla ingxenye ulwazi oluthile njalo. Ukuze Sinqanda ukufinyelela emininingwaneni ebucayi kwabezindaba sibekwe izindawo zigadiwe ukuthi wayazi kuphela kumbuthano elincane labantu.

Ngaleso sikhathi samanje, lapho abathwali idatha babé ngogesi, zikhona izimfuneko ezintsha ukuze kuvikeleke imininingwane yakho eyimfihlo. Kuyinto eyodwa yalezi izindlela uzobe okuxoxwe ngazo kulesi sihloko.

I-computer ingasetshenziswa abantu abafinyelela ezingxenyeni ezahlukene ulwazi olutholakala kulo. Ukuze ubeke umkhawulo ukufinyelela, ukusetshenziswa izinqubo ukuhlonza kanye ubuqiniso.

Ngamagama alula, ukuhlonza nezimpendulo embuzweni "Ngubani idinga ukufinyelela?", Futhi ubuqiniso yombuzo "Lokho uma ungubani luziveza?".

Ubunikazi aludingi namasu, njengoba abafisa ukufinyelela ulwazi obala uzibiza, ukuqinisekisa yinqubo eziyinkimbinkimbi, oqinisekisa ukuvikelwa kolwazi.

Okwamanje, indlela onokwethenjelwa kunayo yonke ubuqiniso ubhekwa omunye lapho uphawu isetshenziswa. Kuyini ithokheni? Siphendule lo mbuzo ngezansi.

Esikhathini izincwadi yezobuchwepheshe Ithokheni lokhu kubizwa ngokusentshenziswa idivayisi ye Ubukhulu encane, ekuqinisekiseni ukuthi ulwazi ukuphepha kanye esetshenziswa, ngaphezu, ukukhomba umnini wayo. Lenchazelo kunikela umqondo wokuthi ukuqokwa, kodwa akuyinikezi isithombe esiphelele nomqondo onjalo, yayiwuphawu.

Yini yithokheni ngomqondo ogcwele, it kuzoxoxwa kamuva. Sizokunika ulwazi oluthe xaxa ngalesi sihloko. Ngo inqubo ingxoxo eyengeziwe igama elithi "Ithokheni" kungase kuthathelwe indawo igama elithi "kudivayisi" icala futhi kuhlanganise ingqikithi ehambisana.

izinhlobo amadivayisi

Lezi zinhlobo ezilandelayo amadivayisi:

• ngaphandle koxhumano;
• zokuxhuma.

Njengoba ubona sihloko, owokuqala ayixhunyiwe ku-khompuyutha. Banezinhliziyo ukubuka uboniswa ngenani umsebenzisi futhi umsebenzisi wokugcina ngesandla wangena computer, iqinisekisa ukufinyeleleka kwimithombo kunesidingo.

Lesi sakamuva kumele lixhunywe ikhompyutha ngendlela yezintambo noma engenantambo. Amadivayisi anjalo Dlulisa iyadingeka uma Ulwazi kwikhompyutha ngokushesha ngemva uxhumano Kumiswa, ngaleyo ndlela asuse isidingo ulwazi ngesandla input.

Ukuze uxhume amadivayisi izintambo kwikhompyutha kudinga input okuhambisanayo, ikakhulukazi, kungaba echwebeni USB.

Isenzakalo esidume kunazo zonke yizona exhunywe zamadivayisi e-USB - amathokheni namakhadi smart.

amathokheni Wireless - kuyini? Le divayisi, okunikeza ukusetshenziswa kuwusizo kakhudlwana, kusukela kumadivayisi kungenzeka, isib, a Fob ukhiye, lula, ikakhulukazi, inqubo ukugcina kwabo.

Eminye imisebenzi eyenziwa amadivayisi

Kulokhu okungenhla ungakwazi kakade tente Nokho ukuqonda okwenyanga mayelana uphawu, yini -ke kusho ukuthini futhi kusebenza kanjani. Nokho, ngaphezu ubuqiniso kanye ukuhlonza, ke unga:

1. Ukuqalisa ukubethela nencazelo ngokuvumelana algorithm ukubethela.
2. Qinisekisa isizukulwane ukubethela okhiye.
3. Yakha futhi uqinisekise isignisha yezinombolo.
4. Yenza hashing idatha.

Ithokheni kungenziwa empeleni wacabangela microcomputer, ngoba unenkumbulo okusheshayo futhi yesikhathi eside kanye ne-microprocessor.

Izinkinga nazo namadivayisi

Nakuba manje amathokheni kukhona izindlela onokwethenjelwa kunayo yonke ubuqiniso, bangase sengozini. Lokho kuqala kunazo zonke okufanele ukwazi ngokuhlanza lo khiye electronic yayiwuphawu? Wokuthi leli thuluzi ingase crack bese ukundlula ukuvikeleka.

Kuyinto sengozini kuyaqondakala - kungcono ukulahlekelwa kwakhe. Kodwa ngokuvamile, izinkinga ababa nazo kudatha yezokuphepha asivelanga, ngoba uma umuntu uthethe kudivayisi, ngeke bakwazi ukuthola ukufinyelela ulwazi olufanele, ngenxa yokuthi ngokuvamile senzeka ezimbili-factor.

Nokho, uhlelo evumela ukuthi umsebenzisi ukugunyaza nge-Inthanethi, okuyinto mayelana nokuphepha akwanele inethiwekhi okunokwethenjelwa angabasengozini, ngoba umhlaseli uyakwazi nokunciphisa imilayezo in exchange of abasebenzisi ezimbili zona izinguquko ezingafanele.

Ngokuvamile, mayelana uphawu isivele wathi zingaphezu kokwaneleyo. Kodwa ngaphezu izincazelo enikezwe ku-intanethi lapho okubhekiselwa kuzo nangokuthi kulemboni. On the inthanethi umbuzo engavamile, "Kuyini ithokheni okungalungile?". Lokhu amacala obuqand awahlobene isihloko okuxoxwe ngawo ngenhla. Kuyinto, njengoba umthetho, phezu izakhi imidlalo ehlukahlukene. Futhi indlela uxazulule izinkinga ezihlobene kufanele zithunyelwe maqondana ngamunye umdlalo othize.
