Nowadays, the computer is quite populer in our daily life. It seems that we cannot work without the computer. Office workers use the computer to get contact with people abroad by email. Teachers use the computer to make PPT for teaching and engineers use the computer to analyze the data. Computers exist in every aspect of our life. However, someone also use computers to cause damage to others. For example, the hacker hacks into others' computers to steal the information or they create computer virus and circulate it on the Internet. Someone also use computers to circulate pornography and violence.
Hence, we should use computers in a right way. Let computers be our good assistants rather than destructors.
