PAL operates at 50 Hz fields per second and is used in which regions?

Explanation:
The key idea is that PAL’s 50 Hz field rate matches the 50 Hz electrical systems common in many regions outside North America, so PAL was adopted broadly wherever those power standards prevailed. Because of this, PAL is used across Europe, Africa, much of Asia, Australia, and various countries in South America—the “rest of the world” outside North America (and distinct 60 Hz regions). That broad geographic spread makes the description “rest of the world (excluding North America)” the most accurate umbrella for where PAL is employed.
