A laptop is one of the best inventions that is beneficial for students’ schoolwork. To begin with, laptops are portable and not bulky, so students can bring them to the library or Internet café to do school projects with their partners. Another benefit is that they are preferable to be used for typing and editing most of students’ given presentations and assignments due to their convenience and versatility. Students also use laptops to interact with their teachers through sending and receiving instant messages on social networking sites, submitting their homework via emails or even doing tests online. Last but not least, a laptop is a useful tool to search for and download learning materials on the Internet. It can store much more learning data than a smartphone or a tablet. In conclusion, a laptop brings various benefits to students, so they should take advantage of its functions wisely.
