PLEASE CHECK MY ESSAY!

It's well known that, computer has a great influence on our life in whole. Everything has changed that's why a process of interaction of teachers and students has changed too. ??In fact, using the high quality technology machines help professors to educate us more effective. Educators can aid pupils which missed the classes and post the important information on the private pages.
Unfortunately, some of rude students try to put down their mentors by using private information, and teachers are forced to protect it. ??In conclusion, I want to add that educators and students should be very careful. Finding right balance between minimal risks and maximum efficiency is the best way to our success.
