+ + +Əgər İngilis dili bilmirsinizsə, bu, sizin üçün böyük bir maneə olacaq. Əvvəlcə İngilis dilini öyrənməlisiniz. Texnologiya və proqramlaşdırma dünyasında baş verən yeniliklər və resursların əksəriyyəti yalnız İngilis dilində mövcuddur. Bu sahədə uğur qazanmaq istəyirsinizsə, İngilis dilini mütləq öyrənməlisiniz. Çünki dil bilmədən yeni texnologiyaları mənimsəmək və beynəlxalq cəmiyyətlə əlaqə qurmaq çox çətin olacaq. Bütün bu resursları anlamadan, dünya ilə ayaqlaşmaq və peşəkar sahədə irəliləmək mümkün deyil. İngilis dili, özünüzü inkişaf etdirmək və bu sahədə irəliləmək üçün ən vacib alətdir. +
