Mar. 30

     Surprise!! There is no quiz this week, hah..
     This week, we learned about network. First of all, professor introduced three ways of connection, and they are roundly connected, centrally connected and all connected respectively. Then, Mr Heap explained the reason why there are a great number of issues about security and privacy in the Internet. In the end, he told us how to avoid personal information being stolen. For example, providing some personal questions in a survey before giving account information to owners. Using personal password to log in.
     The last week is coming, and I hope everyone can get a great mark in final.
