It is assumed that excessive usage of internet among young generations, i.e., students of universities make them more dependent on virtual relationships and socially isolated. Though there are some studies around, which validates these consequences of internet usage done previously for some countries of world but yet, for the country Bangladesh, there is no such study still existing which reveals these issues with in depth analysis, particularly done for any specialized public Science and Technology University, where internet is more viable than to other kinds of universities, because of the additional attention given to information and communications technology there. The study here perhaps is done with a format of semi structured questionnaire; purposive sampling and SPSS software to fill the subsisting gap thus have found the most common kinds of websites used by students, average duration of them in daily basis, whether on other hand, have assessed that students are getting dependent on virtual relationships, though their social isolation score is not that much high till now.
