Computer and Mobile technology are the things necessary for young people in the 21st century. These devices provide them more opportunity to engage into wider communities.
Computer and mobile technology bring both negative and possitive effects, the negative effects are young people will spend more time on playing game instead of reading a real book, or they chat with their friends about all thinks around instead of travelling by themselves to experience the nature.
but I think we should look to the possitive effects of those devices. Mobile technology give youth a chance to learn whatever they like to at anytime they want to learn.
