"A whiteboard (also known by the terms marker board, dry-erase board, wipe board, dry-wipe board, and pen-board) is a glossy, usually white surface for making nonpermanent markings (an evolved version of the blackboard).
Whiteboards are analogous to blackboards, but with a smoother surface allowing rapid marking and erasing of markings on their surface".

"A blackboard (also known as a chalkboard) is a reusable writing surface on which text or drawings are made with sticks of calcium sulfate or calcium carbonate, known, when used for this purpose, as chalk.
Blackboards were originally made of smooth, thin sheets of black or dark grey slate stone".https://en.wikipedia.org/wiki/Blackboard
