I think that the internet is one of the best invention in the world but not the only great invention but can we really imagine the world without internet ? internet made everything close and simple and 

we can find whatever we are looking for .so it is one of the greatest inventions in the world :D

Not only the internet is the most remarkable invention in the world , but PCs are also the brillant invention in the world . Some people may regard people do not have much time to communicate face to face since internet launched , though , the disadvantage cannot oveshadow its benefit after all . I love internet !!

internet allows individuals to communicate with each other from the comfort & safety of their own homes

This is very good,in the long term it helps nation states to better understand each other.

Of course there are always some dishonest people who will use the medium to exploit you.So long as you are carefull, & use common sence it is a power for good in the world. Be lucky !!!
