In particular, it may refer to a new user of computers, and often concerns Internet activity, such as online gaming or Linux use. The origin of this term is uncertain.

History
The etymology of the term is uncertain. It may derive from "newie", which is attested in U.S. and Australian sources of the 1850s, meaning a neophyte in a place or situation; alternatively, it may derive from the British public school slang "new boy" or "new blood", which is attributed to the same era and was applied to a schoolboy in his first term. In the 1960s and 1970s, the term "newbie" had a limited usage among U.S. troops in the Vietnam War as a slang term for a new man in a unit.
