Climate Change

          It is reported that there are several causes and effects of the changing climate that people have to realize. Firstly, expanding temperatures are resulted in changing many violent types of weather. Secondly, dissolving ice and large mass of ice cause increasing sea levels. Finally, changing climate also involves health and well-being of people (Congondis, 2011: 1-5).

          It is said that there are three types of computer virus that cause problems for any users. Firstly, a Trojan Horse takes credit card details or bank passwords. Secondly, a Spyware gathers information about the computer’s owner. Finally, a Spam is used for cheating people and for taking money from them (Philpot, 2011:47).
