I am sorry that I couldn't make you understand my message. I said DIU is one of the best, i never said it's the best or it has no competitors. Also, English word has got multiple meanings. The word 'tool' means not only instrument or devise, but also ways, medium, means etc. Facebook is a tool, so to say, a medium of communication and networking. please don't jumble up with the word, try to grasp the meaning.
Now take for the example MOBILE PHONE, a blessing of modern science. Nowadays the young generation is misusing it, like talking the whole night or even cheating in the examination. A lot of students in DIU have been caught in cheating on mobile phone. Now will you suggest that the use of the mobile phone must be stopped in our life or in DIU campus?
Yes, today we have taken a decision unanimously that mobile phone must be prohibited in the exam hall. But it can be, better say should be used before or after the exam. Let me tell you an incident, we grabbed a student's cell phone during the exam. It was the time when BDR mutiny took place. His mother was calling up continuously to the Head of the Dept. crying that we would be responsible if anything happened to his son.
My point is you can use a knife either for killing or for surgery. But the benefits of modern science should NOT be barred in this age of globalisation. So i think we should always think before making any comment.
Thanks for your reply, anyway
