Books & techs

When it comes to doing work against books and technology. I prefer using a book because it is simple to write and you just turn it in to the teacher . but for technology i have to research my studies which is much simpler but it is also easy to lose your work in a computer. It is so more complicated then sending a photo to a friend in social media. Sometimes i get frustrated when i turn in my work because i get told from my teacher that i never turmed it in.
