Usage notes

There are significantly more meanings of the word within the United States

hacker - Merriam Webster Online (American English) than in other English speaking nations.

The use of the word hacker to indicate a person who displays skill, particularly with computers, may be misunderstood

hack; hacker - Concise Oxford English Dictionary, Oxford University Press (British English) as implying the narrow meaning of unauthorised intrusion into electronic systems (also known as a cracker or occasionally black hat). This serious misunderstanding in the field of computer expertise is perhaps particularly common outside the United States.

Some computer enthusiasts object to the use of hacker for a person who breaks into computer systems, preferring cracker for this sense.
