Scrum Board
Visualizing the work of the Scrum Team via a board (either virtual or physical) is a common practice used by Scrum Teams. The purpose of creating such a board is to create transparency of information.
While the Scrum Guide doesn't prescribe any specific practice or a board, it's valuable tool to enhance shared understanding and empiricism.
The Scrum Board may contain the list of everything that's needed in the product (a Product Backlog) and the work of the current sprint (Sprint Backlog).
