Yintoni na iinkqubo ulwazi? Lungelelanisa iinkcukacha: ntetho, isifundo

Iinkqubo Inkcazelo - iinkqubo ezinxulumene uphendlo, ukugcinwa, translation, ukusetyenzwa, Kakade ke, ukusetyenziswa kolwazi ezahlukeneyo. Ngelo xesha linye zahlulwe iintlobo eziliqela, nganye eneyazo awohluke zalo kunye ubuqili.

Olu lwazi iinkqubo ezijolise ekolulweni ukufunyanwa data egcinwe. Kukho iinketho ezininzi njani ukukhangela:

• zoviwo ngqo;
• unxibelelwano kunye neengcaphephe ezahlukeneyo malunga nomba ukuba unomdla;
• Ukufunda amaxwebhu afanelekileyo kunye neencwadi;
• ukubukela umabonwakude neevidiyo;
• ngokuphulaphula kunye usasazo;
• umsebenzi ngqo oovimba kunye nezibonelelo zethala leencwadi;
• ngombuzo iinkqubo ezizodwa ulwazi, kunye neebhanki kunye neziseko nedatha yekhompyutha;
• Ezinye iindlela.

Qonda ukuba loluphi ulwazi kungafunyanwa kwiimeko ezahlukeneyo abathimbe bona ngqo iinkqubo ukufuna ulwazi - ezi zakhono ezizezona zibalulekileyo imihla yethu.

Collection nokuStorisha

Ngoko nangoko kufanele kuqatshelwe ukuba nje ukuhlanganiswa kweenkcukacha ayikwazi kuba isiphelo ngokwalo. Ukuze ube intsingiselo iinkqubo zolwazi kunye lwazi ezithathwe kungaba indlela enye okanye omnye asetyenziswa, kuyimfuneko ukuqinisekisa ukugcina lwabo, ngamanye amazwi ukuba usebenzise indlela lwe data zokwabelana kwisithuba kunye nexesha. Xa kunjalo, le ndlela iya kuxhomekeka ngqo kwi ngenkxaso esetyenzisiweyo. A computer isetyenziselwa ukubonelela yokugcina indawo iinkcukacha ezifanelekileyo ze uvumele ngaloo ndlela umsebenzisi ukufikelela ngokukhawuleza iifayili umdla kuye.

Inkqubo yolwazi kukodwa yokugcina jikelele lolwazi, ukuba iinkqubo zolimo, uphando, ukubeka kunye nomnikelo elandelayo data ezahlukeneyo. Ngamanye amazwi, le nkqubo onjalo ukusebenzisa phantse naziphi na iinkqubo ulwazi. Ubukho kweenkqubo ezinjalo - iphambili iinkqubo zenkcazelo mihla ngokupheleleyo buyazohlula data cluster standard ngaphandle kokwenza naziphi na iinkqubo ulwazi.

Umzekelo, naliphi na ithala leencwadi, nto leyo eya kuba nako ukuyisebenzisa kuphela umnini wayo, akunanto yakwenza nesibakala sokuba olo lwazi kwiinkqubo kule nkqubo. Ngelo xesha elifanayo ezahlukeneyo zokugcina karhulumente umyalelo iincwadi zokugcina ichazwa ngokungqongqo. Kungenxa nkqubo wophendlo yokusiwa kwee yeencwadi okanye indawo yabo kutshanje eziye kufika kwi kwithala leencwadi, ngumgaqo semthethweni. Kungenxa yoko le nto, ukuya elayibrari, omnye ngokukhawuleza uyaqonda ukuba iinkqubo lwazi kunye nendlela ukubaleka.

ukudluliselwa

transmission data - nto losasazo ulwazi ukusuka kumthombo ukuya khona. Kulo mzekelo, ucinga ukuba uhlobo enjalo kweenkqubo transfer lolwazi, ngoko nangoko waphawula ukuba apha ngokuyimfuneko inxaxheba imvelaphi kunye umamkeli, ugqithiso lwedata lokuqala inxaxheba ngqo, ngoxa yesibini lilelakhe. Phakathi kwabo usebenzisa ethile ijelo transmission ulwazi, nto leyo kwizangqa neyobungcali ngokuba ijelo lonxibelelwano.

Ukukhumbula izifundo, apho uchazelwa iinkqubo zolwazi (Grade 10), siphawula ukuba ukongeza umamkeli, kwaye ufumana le unxibelelwano iquka uluhlu lwezixhobo:

• izinto zobugcisa adlulisele uphawu oya kuyo kumthombo othile;
• khodi uguqula umyalezo original ibe imbonakalo elikhethekileyo kakhulu lula ukugqithisa;
• candelo lenza yinguqu kokuhlaziya ekuqaleni ukuyifunda isixhobo yokuqala.

Yintoni na iinkqubo ulwazi? Ubomi bethu inxulumene ngqo losasazo data. Xa inkqubo yokunikezela ulwazi igqwethekile kancinane okanye ezilahlekileyo. Umzekelo iphawulekayo yale ke uphazamiseko ezahlukeneyo emoyeni kunomathotholo, isandi utshintsho nefoni, engekabuyi umfanekiso kwi TV, kunye nezinye iimeko ezininzi. ezinjalo, okanye njengoko ibizwa kwiingcali, ingxolo, abanye bayasigqwetha data, kodwa la beba wabulela ngaphantsi yaye ngaphantsi ebonakalayo kuphuhliso eqhubekayo kwinkalo cryptology.

Yintoni ze?

Ngokwazo, ezi namajelo yahlulwe simplex kunye kabini, ngokuxhomekeka ithwalwa ngayo zosasazo. Nicinga ukuba olo lwazi kwiinkqubo kwinzululwazi, badla ngokujongana iinkqubo kabini xa data kudluliselwa macala omabini, ngoxa simplex ukunika ukudluliselwa kwicala elinye kuphela kwaye ziqhotyoshelwe apha kule TV. Ngomzila efanayo imiyalezo ezininzi nga kusasazwa ngqo ngexesha elinye, ngamnye yahlukanisiwe ukusuka kwenye esebenzisa okucoca ezizodwa. Umzekelo, uyakwazi ukucwangcisa rhoqo lokucoca yemiyalezo zosasazo enokufunyanwa kaninzi kwi imiphantsi kunomathotholo.

Ziziphi iimpawu ze?

Itshaneli data uneempawu ezimbini eziphambili, ezifana bandwidth kunye nezifo ingxolo.

Eyokuqala ichazwa inani loonobumba zinokusasazwa engekho sokuphamazisa. Olu phawu luxhomekeke ngqo kwi kwiimpawu ebonakalayo umjelo.

Ukuze kukhuselwe umzimba engcono ingxolo, kusetyenziswa ubuchwepheshe transmission ezizodwa evumela ukunciphisa impembelelo yengxolo. Umzekelo, apha ungaquka abalinganiswa ezongeziweyo, leyo ngokwabo Awunayo nasiphi na isiqulatho ngokwenene kodwa zisetyenziselwa ukuqinisekisa ulawulo kangangoko phezu ukuchaneka umyalezo emva kokuba sifunyenwe liGosa uthunyelwe ezi.

Xa ingxaki othile jamming ukhuselo kwityala kanye, ukuba sicinga ukuba olo lwazi kwiinkqubo kwimizobo.

processing

Lweenkcukacha imele ukuguquka kwazo ukusuka kwesinye isimo ukuya kwesinye, yaye le nkqubo yenziwa ngokwe imithetho engqongqo esesikweni.

Ngokwawo, unyango kufuneka kufana siseko kwibhokisi emnyama - inkqubo apho umsebenzisi ufuna kuphela ukujonga ulwazi igalelo nemveliso, kodwa imigaqo ngawo ukusebenza lwenziwa, kunjalo ngokubanzi akanamdla kwaye nkqu kuthathelwa ingqalelo.

Black Box yinkqubo elikhethekileyo ofihla ngokupheleleyo iinkqubo yintoni inkcazelo. Kwinzululwazi yekhompyutha, izixhobo ezo badla ngokuba ababhalisi. Xa idatha wangaphandle kubonelelwa kuphela inkcazelo malunga igalelo kunye neziphumo zale nkqubo, xa isakhiwo kunye zangaphakathi iinkqubo ezininzi azibonakali.

ukusetyenziswa

Olu lwazi lusetyenziswa ekwenzeni izigqibo ezithile. Kulo mzekelo, ukuchaneka, ukuphelela, yaye, okona kubaluleke kakhulu, ulwazi njongo likuvumela ukuba wenze izigqibo, yaye ukuqonda oko kufuneka kwenziwe iinkqubo ulwazi. Grade 8 amaziko ngamaziko emfundo ibandakanya isifundo esi sihloko zolwimi ngokunzulu. ukukwazi kwakho ukususa kwaye ziyafumaneka ukwenzela abanye ukuba babonise ulwazi luncedo ukunxibelelana nabanye, ngoko ke kunokuthiwa ngaphandle ubaxo ukuba uyakwazi ukunxibelelana, okt nokutshintshiselana ngengcaciso kunye nelungelo lokusebenzisa ngayo iinjongo zabo - yenye olubalulekileyo bobuchule abantu namhlanje.

Yintoni ekufuneka uyazi uze ube nako indoda namhlanje?

nokubhala computer ngexesha lethu inikeza:

• ulwazi yintoni injongo ephambili nasiphi na isixhobo kwi PC mihla;
• ukuqonda iintlobo eziphambili software ezisetyenziswa kwiikhompyutha, kwakunye neentlobo lwenjongano umsebenzisi;
• ukukwazi ukucinga, ukugcina kunye ukuprosesa ulwazi lomzobo kwaye lwamanani, esebenzisa software eyodwa.

Ukuba ungenza ukuba, okulungileyo into ulwazi kwiinkqubo ngokwendalo kwi computer, kwaye kwakhona ukuzisebenzisa ngobulumko - unazo zonke makings ukuba umntu ngempumelelo. Kwaye oku yeyona nto ibalulekileyo.
