M-learning is learning supported by mobile devices and intelligent user interfaces. Compared to the prior generation a few years ago, storage capacity and screen size of mobile devices as well as transfer speed of wireless connections have significantly increased. Equipped with mobile devices, learners can conduct learning activities at anytime anywhere. M-learning is learning that is not constrained to a physical space or specific time and learning that is supported by communication with embedded computing elements in the environment on every move of the learner (Thiyagu, K, 2009). The main aim of the study is to assess the perception towards mobile learning activities among post graduate students in Viruudhunagar district. Survey method is employed for this study. The investigator has chosen 230 post graduate students as a sample for the study in a random sampling technique. Finally the investigator concludes; (i) There is no significant difference in perception towards mobile learning activities among the post graduate students with respect to their course in terms (ii) There is no significant difference in perception towards mobile learning activities among the post graduate students with respect to their Father's Educational Qualifications and father's occupation.
