Electronic whiteboards, also known as interactive whiteboards, are large display screens that can be connected to a computer and used for presentations, teaching, and collaboration. They allow users to interact with the content on the screen using a stylus or their fingers, and can also be used to annotate, draw, and manipulate digital content.

They can also be used to save and share the content created during a session. **
