We are living in a global village and mostly depending on the information which we have from the internet on our smartphone.
Perhaps most of the time we are not fully satisfied and we feel that we should consult with a book about the matter we are searching for.
After this experience, we conclude that although the smartphone and internet are more capable and fast than the book to find out something.
But we can not deny the importance of books because every book is not available on the internet.
So we can say and we sure that book is also important and a smartphone is a smart tool to solve our need for knowledge.
