Now a days college students as properly lecturers are attending seminars, conferences, workshops at nationwide and worldwide stage by utilizing the multimedia techno-resources like PowerPoint and even they pursue a wide range of essential programs of their alternative in distance mode by way of on-line studying methods. On-line studying facility has opened infinite variety of doorways of alternatives for at the moment’s learner to make their life happier than ever earlier than.
