What is a Computer?

In my lifetime, 80s – today, the word computer often refers to Desktop or Laptop.  I believe this to be too narrow of a definition.

Is a DVD player not a computer?  Or an Alarm clock?  Or a microwave?  Or a TV?  They all perform computations today.  They are or have computers in them.

My goal with this post is to help educate people that computers are all around us.
