The Central Source for all Jargon

Technology - Hackers

Hacker's use a lot of jargon in an effort to be trendy or cool. Much of it means nothing other than to the hacker’s community themselves. Hackers are a crazy bunch often misunderstood and their hackers jargon merely serves to keep their retorict amongst themselves never to be shared with the wider community.

Hacker’s jargon is also evolving to cover newly created techniques for busting code or web site for example. Most people see hackers as an innocuous bunch of sados until they become adversely affecetd themselves by the hackers exploits such as a defaced web site or corrupted computer system through email.

Understanding the hacker’s jargon may go someway to understanding their thinking & methodology. Some hackers see themselves as ‘white knights’ of cyber space seeking out week public unsecure systems. Others see hackers as nothing other than thieves or malicious raiders seeking glory or self gratification at others expense.

Whatever your view point, our hackers jargon section will certainly entertain.
