Cyber Protection and what not to post on the Internet

Today in Globaloria class, I learned about cyber safety, and the importance of not giving out any information on the Internet to anyone. Also, I learned that there are many things out there on the Internet that are hamrful to students. Just remember to be safe on the Internet.
Another thing, when you are on your email and you do not know who the sender is, do not open it. It contains spyware and they will get all your information.
