Attempt This Question
Not attemptedCorrect Answer: (b) 1 and 2
A smart card is indeed a plastic card embedding a micro-chip (statement 1). Digital transmission technologies such as satellites and fibre-optics primarily use digital (not analogue) techniques (statement 2). A digital library need not be confined to the Internet; it may be stored locally on CD-ROMs or intranets (statement 3 is wrong). Therefore only statements 1 and 2 are correct.
