We have to admit that the Internet has been bringing us a lot of advantages since it appeared. However, there are also many disadvantages as well as risks coming from it. Firstly, Internet can be a very good form of entertainment. We can listen to music, read books, watch videos, and play games on it. Some of the websites provide good and healthy environment for users to have fun, but some of them contain toxic images as well as inappropriate information for teenagers. Parents should have the control of the computers, and they should limit the access in order to keep their children safe. Secondly, many people can find useful information and necessary knowledge on the Internet. It saves us a lot of time to search on the websites instead of going to the library and turn every single page of countless books to get what we need. However, it is also difficult for us to ascertain all of the things we read on it. Not everything on the Internet is true since it is formed by many different users, and there are just some of the websites among million ones that is actually trustworthy. We need to double check all of the information from many sources to make sure that we get the right one, and we should not rely too much on it. Thirdly, Internet is the place where people can post and share their information. We can meet and make friends with a lot of people, and it creates a huge community. By doing it, we give Internet and App providers the permission to get our personal information, and it is a huge chance for cybercriminal to take advantages from their mistakes in securing information. In conclusion, Internet is a two sided tool. If we know how to use it properly, it can be our best assistant.
