A computer literacy of all participants and an adequate technical equipment are both necessary for an effective e-learning implementation into the process of education.

The article reports on a personal experience of teaching Greek and Latin medical terminology at the First and Third Faculty of Medicine in Prague, where undervaluation of these preconditions is a serious factor which limits the improvement of the e-learning. An emphasis on the lowest time expenditure possible leads, among others, to substantial limitation in the interactivity.
