Uhlobo luni lokumelwa kolunye uhlobo lweedatha? Iintlobo zolwazi.

Enye yezinto ezizithandayo kwiimvavanyo zabafundisi bezikolo kunye nezifundo zokuqala zeeyunivesithi kwi-informatics "Ziyiphi indlela yokubonisa uhlobo olufanayo lweedatha? Ziziphi iifom owaziyo?". Ngelishwa, kwiimeko ezininzi zifuna impendulo ekhethekileyo, echazwe kwiincwadi zezifundo, kodwa ingaba lichanekile kangakanani? Masiqale ukusuka ekuqaleni ukujongana nale ngxaki.

Inkcazo

Ngaphambi kokuba uphendule umbuzo: "Nguwuphi uhlobo lokumelwa kolunye uhlobo lweedatha?", Makhe sibone oko kusemngciphekweni. Idatha (ulwazi) iqoqo yolwazi malunga nehlabathi elijikelezile, nto leyo into yokucwangciswa yiinkqubo zekhompyutha. Ziziphi iintlobo kunye neefom zokumelwa kwedatha?

• Isandi. Yona ndlela yokuqala yokudluliselwa kwedatha emhlabeni. Lawa ngamazwi, izandi ukuba indawo yethu iphuma ukuhambisa ulwazi kithi.
• Igraphic. Imizobo yeDwala, imidwebo yabantwana, imifanekiso, imidwebo.
• Umbhalo. Emva kokuba ufunde ukudweba, uluntu luye lwagqithisa kwimo engqongqo yenkcazelo yokumelwa, ephuhlise "i-code" ekhethekileyo, enokuthi ichazwe nayiphi na into ejikelezayo.
• INombolo. Isinyathelo esilandelayo kukulinganisa iiparameters zento.
• Ulwazi lwevidiyo, olubonakala ngasekupheleni kwekhulu le-19 leminyaka.

Ukuvumelana

Njengoko ubona, kukho ezininzi iintlobo zolwazi. Ngendlela emfutshane ukubonakaliswa kolunye uhlobo lweedatha kungabizwa njani? Ukuba ucinga ngako, kunzima ukusho ngokungaqinisekanga ukuba kukho indlela enjalo. Ngakolunye uhlangothi, zonke iindidi zolwazi, esizichaze ngasentla, zikho uhlobo lokudluliselwa, kunye noluhlobo olufanayo lweedatha. Ngakolunye uhlangothi, amanani okanye amanani angabonakaliswa kumfanekiso, ngoko ke ootitshala nabafundi bafuna ntoni kubafundi? Kutheni lo mbuzo uvame ukubangela ukuncipha kumanqaku abafundi?

Phendula

Ukuba kuwe ekubhaliseni umbuzo: "Ifomu yokumelwa kwedatha efanayo" ibambe, ukuhluka okukuphela kokuchanekileyo kwempendulo kuba yi-tafile. Ngokuqinisekileyo, oku akumangalisi ngokwaneleyo, kuba kusetyenziswa iiseli zetafile kunye namafomula, kunye neetekisi, kunye nemidwebo, kwaye kwezinye izicelo zingafakwa kwiseli kunye neqhekeza levidiyo. Ngoko iphi i nyaniso? Inyaniso kukuba kulo mzekelo "uhlobo olulodwa" luthetha idatha enokudibaniswa ngesizathu esithile. Oko kukuthi, kwikholam yokuqala - unyaka wokuzalwa komntu, okwesibini - ifani yakhe. Kwaye akunandaba nokuba le ngcaciso ibhaliwe kwileta, iinombolo, ezithathwe okanye ezimele njengefayili yomsindo. Yonke idatha evela kwikholam enye iya kuthatha intsingiselo efanayo.
