If you're a novice at snowboarding, you're just learning the sport. On the Internet, a novice might be called a newbie, but your parents would call one a beginner.
Novice is derived from the Latin word novus, which means new. A novice is new to what they do, so a novice photographer is just learning how to take nice pictures. Other words related to novice are novel "new, unusual," and innovate "to invent, begin with new ideas." Novice can also mean a member of a Christian order who has not yet taken their vows.
