Input: Consider Input: Person1: Hey , Mike . You've been surfing the Net for quite a while . What on earth are you searching for ?
Person2: It's something relative hackers . I often hear people talking about them , but I don't know much about them .
Person1: Well , roughly speaking , a hacker is a computer buff .
Person2: You mean a guy using enthusiastic and knowledgeable about the computer ?
Person1: You can say that .
Person2: But why are people always having such a negative attitude towards them ?
Person1: They must have mixed hackers with crackers .
Person2: What is crackers then ?
Person1: There is another group of people who loudly call themselves hackers , but they aren't . They break into computers and break the phone system . Real hackers call these people crackers , and want nothing to do with them .
Person2: So they are two totally different concepts .
Person1: Well , the real hackers mostly think crackers are lazy , irresponsible and not very bright , and feel that being able to break security does make you a hacker any more than being able to start cars without keys makes you an automotive engineer . Unfortunately , many journalists and writers have been fooled into using the word hacker to describe crackers . This irritates real hackers to no end .
Person2: I see . Then the basic different is , hackers build things , crackers break them .
Person1: You got it .
Person2: Thanks a lot .
Person1: You are welcome .
