LONDON, England (CNN) -- If mention of The Pirate Bay conjures up images of parrots, peg legs and planks, or geeky jargon like BitTorrent and jailbreak leaves you all at sea, this handy A-Z will help you navigate the choppy waters of the online piracy debate.





"X-Men Origins: Wolverine," starring Hugh Jackman, was downloaded over a million times after being leaked in early April.





The Screening Room's indispensable lexicon of online piracy will teach you cracking from key generators: You'll never again be caught out wondering how "X-Men Origins: Wolverine" fits into warez.





A is for anti-piracy  Efforts to prevent the illegal transfer and use of copyrighted material -- often spearheaded by corporate associations like the Motion Picture Association of America (MPAA) -- using a variety of digital rights management (DRM) tools like encryption, product keys and serial numbers. Technologically often a step or two behind the pirates, the entertainment industry will sue for breach of copyright.





B is for Bill Gates As early as 1976, Gates wrote an open letter saying that software piracy could be a problem. Ironically, he has since said that Microsoft actually benefited from piracy in China, where over 90 percent of computers use Windows, most copies of which are pirated. The widespread use of Microsoft's operating system has enabled the software giant to gain pole position in the fast-growing market.





C is for cracking  Modifying software to remove copy protection -- one of the technologies companies use to prevent unauthorized reproduction of media -- to enable the illegal duplication and proliferation of pirated material on disks and online. Mostly done by hackers, not usually for money but to gain respect within the hacker community.





D is for digital rights management (DRM) Access-control technologies used by manufacturers. Most pirating technology is created to circumvent various types of DRM in order to share copyrighted material online. Apple rid its iTunes library of DRM in early April, but is charging users 30 cents per song to upgrade to DRM-free tracks.





E is for encryption Originally used by militaries to protect secret message transmissions, encryption allows a user to transform and "lock" information that, upon transfer, can only be opened by a person who has the right "key." Encryption software is one of many anti-piracy measures designed to prevent the spread of copying and transferring copyrighted material.





F is for Free Culture movement Led by Harvard law professor Lawrence Lessig, the movement believes restrictive copyright laws are strangling humanity's creativity. Under Lessig's "Creative Commons" organization, the movement is advocating for the free copying and modification of creative works -- and rejecting what they perceive to be the culturally oppressive "permission culture" of copyright and intellectual property.





G is for Global Software Piracy  This report by the Business Software Alliance suggested that 35 percent of software installed on PCs worldwide in 2006 was pirated.





H is for hackers  Hackers "wiped," or erased, all the data from the Recording Industry Association of America's (RIAA) Web site in 2008. The incident, which exposed serious flaws in the RIAA's web security, was an embarrassment for the group, which represents the recording industry of the United States.





I is for International Federation of the Phonographic Industry (IFPI)  According to the IFPI's 2008 Digital Music Report, up to 80 percent of data traffic via Internet service providers (ISPs) is involved in the illegal transfer of pirated material.





J is for jailbreak Mostly commonly associated with the iPhone, it is the practice of downloading illicit software designed to bypass digital rights management, allowing people to upload pirated versions of official iPhone applications for free and use them on their phones.





K is for key generators Small programs found on pirate sites that allow users to crack open key-locked software like Microsoft Office or Adobe Photoshop by generating valid serial numbers for pirated copies of software that would otherwise only be included with legitimately purchased copies.





L is for Limewire One of the oldest and most popular peer-to-peer (P2P) file sharing clients, Limewire
