PREFACE Everyday innumerable technologies are invented and developed all over the world in many fields. Added to this, many technologies have resulted in failure also. One, who is born, has to die one day. During this short span of life, the thrust for new technologies and developments have not quenched yet. As a result of this, many latest technologies were introduced. This magazine “ INFOLINE ” was aimed to provide basic necessary information about the latest technologies developed and it also creates awareness to the one who is reading this. Your comments and valuable suggestions for the improvement from the students, teachers and friends are warmly welcomed and will be gratefully acknowledged.
