A whiteboard is a smooth, glossy surface used for writing or drawing with dry-erase markers. It is commonly found in classrooms, offices, and meeting rooms, making it a popular tool for teaching and brainstorming. The ability to easily erase and rewrite makes whiteboards versatile for sharing ideas and information. Many whiteboards come with a magnetic backing, allowing users to attach notes or other materials. They can be used for everything from simple doodles to complex diagrams. With the rise of technology, some whiteboards are now digital, enabling users to save their work and share it instantly with others, enhancing collaboration in spaces like business meetings and educational settings.
