In my opinion, those technologies are the tool for students to learn and gain access information. Take for example, when we have to do project or homework, we may need to search information, word process the content and present the project by using the computer. There is much information in the internet. When we want to make a birthday cake, we can search the recipe in the internet immediately. You can look up for the dictionary machine instead of the bulky cumbersome dictionary. At school, teachers use the projectors to teach instead of the textbook.
