Product Roadmap and Product Backlog

[junaid]

I understand product roadmap can span over years with quarterly milestones and evolve with learnings. What is the difference between Product Roadmap and Backlog from exam point of view. What to look for?

Product Backlog- includes product vision and high level goals to achieve that vision.

Product backlog - includes user needs to achieve those goals.
