Large interactive whiteboards are digital boards that allow users to display and interact with content using touch or special pens. They are commonly used in classrooms and meeting rooms to enhance learning and collaboration. With these boards, teachers and presenters can write notes, draw diagrams, and share multimedia presentations, making lessons more engaging. These boards connect to computers and can display anything from PowerPoint slides to videos. Users can easily save their work, share it with others, and even access the internet directly from the board. This technology helps create a more dynamic and interactive environment for both students and professionals.
