TECHNOLOGY

Hi, I want to talk about modern technology and answer to questions.
It seems to me, that on-line information will not to replace printed books, magazine and newspapers. On the one hand, information on computers are free, you can find all what you want. For example, Internet is the largest book in the world. On the other hand, laptop computer is heavier and larger than a book, magazine or newspaper.
I believe that in future we will use computers and the software instead of books. Computers will be replacing books. It is will not expensive, if we will use the computers for twelve years. teachers must to write all the information and submit into the computers of students.
When I do homework I use the computer and the Internet: i look for information, use dictionaries, encyclopedias. In the school I use computer in informatics lessons.
More indefinitely used in education will be computers instead of books, and electronic board.
Finally, I hope that the study with modern technology will be easier.
