Definition of whiteboard

The term "whiteboard" is a relatively recent invention, appearing in the 1960s. It's a combination of two words: "white" and "board." The "white" part refers to the color of the surface, which contrasts with the black or colored markers used to write on it. "Board" refers to the flat, rigid surface that serves as the writing medium, similar to a traditional chalkboard. While the term "whiteboard" became popular in the late 20th century, the concept of using a smooth, white surface for writing has been around for much longer, dating back to ancient civilizations using stone or clay tablets.
