    INTRODUCERE

    Prezentul auxiliar curricular a fost realizat cu scopul principal de a oferi un sprijin n activitatea de nvare a elevilor, avnd ca referin unitile de competen din Standardul de Pregtire Profesional pentru specializarea tehnician operator tehnic de calcul. Suplimentar, auxiliarul i propune s orienteze i s ajute cadrul didactic n activitatea de proiectare, desfurare i evaluare a procesului de nvare, pentru obinerea unor rezultate ct mai bune.

    Fiecare material din auxiliarul curricular (activiti de nvare, documente de evaluare, anexe, glosar, bibliografie) i aduc o contribuie difereniat la realizarea competenelor tehnice specifice modulului Comunicaii de date i reele de calculatoare.

    Modulul Comunicaii de date i reele de calculatoare se desfoar pe durata anului colar astfel :

    - 31 ore - teorie - 45 ore - laborator tehnologic

    Auxiliarul nu acoper integral, toate cerinele din Standardul de Pregtire

    Profesional. Pentru obinerea Certificatului de atestare profesional, este

    necesar validarea tuturor competenelor conform criteriilor de performan i a
