Lesson 10: The Past - what is a computer?

This lesson brings the discussion back to the first lesson in the unit, in which we discussed what is and isn’t a computer. Students will look at the analog computers, precursors/pre-computers, and early digital computers. For each device shown, students will see what discoveries it was used for and why it was important to computers today. This will help students see that computers come in different shapes and have fulfilled different purposes throughout time.
