Scrum defines three roles: Product Owner, Scrum Master, and Development Team. The role of Project Manager is not part of Scrum.
The Product Backlog is an ordered list of everything that might be needed in the product. It is the single source of work for the Scrum Team.
Sprint Planning results in a Sprint Backlog, which includes the Product Backlog items selected for the Sprint and a plan for delivering them.
The Daily Scrum is a short meeting where the Development Team synchronizes activities and plans work for the next day.
The Sprint Review inspects the product increment and adapts the Product Backlog. The Sprint Retrospective inspects the process and team dynamics to improve future Sprints.
