Yintoni na ke ungubani, yaye oko kusetyenziswa phi?

into nganye kufuneka akwazi ukuchonga ngandlel 'ithile. Ukuba ibali lwenziwa malunga netafile, kuyimfuneko ukuba ukukhankanya ukuba ikhangeleka njani, oko bagi indlela apho umi. Kodwa indlela yokubona izinto iindidi ezingaqhelekanga ezifana ezifana information technology? Kule kwaye iya kuba inqaku.

Into ebizwa ngokuba identifier?

Yintoni ungubani? Kutheni lento kufuneka? isazisi esisodwa selizwe ebizwa impahla into apho kunokuthi bodwa kwabanye abaninzi. Ngokuqhelekileyo, bahlukene kwezi ntlobo:

• uphawu unique zombane (isebenza kuphela iisekethe kwifowni);
• impahla eyodwa into.

isazisi data inika inkcazelo malunga nalapho kufuneka igcinwe. Kwakhona ibonisa into uhlobo ukuze basindiswe (umbhalo, inani elipheleleyo, okanye ezinye). Ngenxa indlela identifier data eyenziweyo imali kunye nokusetyenziswa kwazo ezilandelayo.

iimfuno ID

Ukuba sithethe ungubani, nto leyo edlulisela ipropati eyodwa into, ngoko zinokwenziwa neemfuno ezifana nokusetyenziswa kuphela amaxabiso Latin oonobumba okanye yamanani. Kusenokubakho ezibonisa ezithile yobukhulu balo.

Xa sisebenza kunye uphawu isazisi elektroniki kufuneka isetyenziswe kuphela ukuba ipoti ye isenzo esisodwa. Ngoko ke, umzekelo, xa ufuna ukwenza inqwelo-moya elawulwa unomathotholo, ngoko ngenxa ukuvula / uvale motor kufuneka ihlangane into enye (ukuba akukhange kubekho matyala ukuba injini ngokwayo sele uqalile okanye, icala, ngexesha engalunganga off).

Ukusetyenziswa identifier kuphuhliso lweenkqubo stand-alone

Yintoni na ke ungubani, xa sincokola ngayo ngokunxulumene esebenza ngekhompyutha kunye nesicelo software phezu kwaso? Kufuneka ubonelele ukusetyenziswa nangaphezulu komntu omnye, ukuze ukuba ukudala izicwangciso zabo ezizodwa, ulande ezi parameters Xa uziyilela iinkqubo. Kunye ekhombayo data kuzakuvumela uku chaza ukuba iziphumo zomsebenzi nalapho kufuneka igcinwe ukuze isetyenziswe kwixesha elizayo. Ngoko ke, isazisi Windows uyakwazi ukubona apho ufuna ukugcina kwimpumelelo eyenziwe "uLizwi" okanye "Eksele".

Ngokuqhelekileyo, onke amasimi apho ulwazi wangena, sibe identifier ethile coinciding kunye database efanayo. Oku kwenzelwa ukuqinisekisa ukuba xa kuthe kwakho iingxaki ungenza ngokukhawuleza ukufumana iindawo ingxaki.

ID akhona nokuba intliziyo ezisisiseko xa besebenza kunye neenkqubo. Lukhona kuba iiseli memory of kwikhompyutha nganye. Oku kusebenza zombini imemori non-eguquguqukayo, nenkunzi yemvu. Xa ubhekisela Iseli nganye, kuqala ngokuba ID yakhe, yaye ngoko ke idatha ngaphezulu.

Yintoni na isazisi kwiinkonzo online

Ekhombayo kwiinkonzo online kusetyenziselwa ukuqaphela abantu ezahlukeneyo kwaye kufuneka nokudlulisela imijelo data ezahlukeneyo. Umsebenzisi ngamnye unikwe inombolo ekhethekileyo, apho ziqhotyoshelwe ithuba elikhethekileyo: ukugcina isixa esithile data ukuze udlulise ulwazi kukho ulwandiso ethile okanye ubungakanani, isantya kunaniselwano data.

ID xa ukusetyenziswa womnatha ngalo naliphi na into. Apho ke kule iinkcukacha kunye ukutshintshiselana iifayile ngolwazi, leyo elawula ukutshintshwa bonke kuyimfuneko. iqhekeza nganye epheleleyo lwe data isebenzisa isazisi yayo. Yena kukuvumela ukuba ufumane phakathi yonke uluhlu lolwazi. Ngoku, emva kokufunda eli nqaku, niya kwazi ukuba yintoni na isazisi kunye, xa kukho imfuneko, ukwazi ukuyicacisa kwabanye abantu abangaqondiyo kulo mbandela na.
