A whiteboard is a smooth, glossy surface used for writing or drawing with special markers. It is commonly found in classrooms, offices, and meeting rooms. People use dry-erase markers to jot down ideas, make presentations, or teach lessons. The writing can be easily wiped off with a cloth or eraser, making it reusable and convenient. Whiteboards come in various sizes, from small handheld versions to large wall-mounted boards. They are often used in collaboration settings, allowing teams to brainstorm and visualize their thoughts. Some modern whiteboards even have digital features, enabling users to save their notes and share them online.
