谁给我一个关于黑客的英文介绍或文章要幻灯片（PPT）
he term "hacker" has a number of different meanings. Several subgroups with different attitudes and aims use different terms to demarcate themselves from each other, or try to exclude some specific group with which they do not agree. In a computer security context, it is often synonymous with a computer intruder.
Paul A. Taylor quotes Steven Levy when describing the hacker ethic as:[7]
1. All information should be free;
2. Mistrust authority--promote decentralization;
3. Hackers should be judged by their hacking, not bogus criteria such as degrees, age, race, or position;
4. You can create art and beauty on a computer; and
5. Computers can change your life for the better.
It is common among hackers to use aliases for the purpose of concealing identity, rather than revealing their real names. Members of the network hacking scene are often being stereotypically described as crackers by the academic hacker subculture, yet see themselves as hackers and even try to include academic hackers in what they see as one wider hacker culture, a view harshly rejected by the academic hacker subculture itself. Instead of a hacker – cracker dichotomy, they give more emphasis to a spectrum of different categories, such as white hat (“ethical hacking”), grey hat, black hat and script kiddie. In contrast to the academic hackers, they usually reserve the term cracker to refer to black hat hackers, or more generally hackers with unlawful intentions.

黑客是什么意思?
概述黑客最早源自英文hacker，早期在美国的电脑界是带有褒义的。但在媒体报导中，黑客一词往往指那些“软件骇客”(software
cracker)。黑客一词，原指热心于计算机技术，水平高超的电脑专家，尤其是程序设计人员。但到了今天，黑客一词已被用于泛指那些专门利用电脑网络搞破坏或恶作剧的家伙。对这些人的正确英文叫法是Cracker，有人翻译成“骇客”。
