ELI5: The difference between the Taliban and Al-Qaeda!

Often it seems like I hear these two terms used interchangeably. Are they one group under different names? Are they two completely different groups with unique ideologies? Do they operate in different areas of the world, separately? 

Edit: I appreciate the answers given. Thanks for the discussion.

The Taliban is an Islamic Fundamentalist and political movement principally in Afghanistan. Among other things, it was temporarily the ruling political force in the Islamic Emirate of Afghanistan from 1996 to 2001, which controlled roughly 90% of the country.

Al-Qaeda is a global militant Sunni Islamist organization, that largely functions as a decentralized armed force. They frequently instigate sectarian violence against other Muslims through pronouncements of takfir, where essentially Muslims with variations from what they consider ''appropriate'' Islamic practice (liberals, Shias, Sufis, etc) are considered apostates. 

They have offered support to one another, have had shared, and differing goals, and even within Al-Qaeda itself there are groupings and splinter groupings with numerous different motivations and even occasionally conflicting goals.
