1a: Describe the history of software and computer design

The study guide:
** 1a. Describe the history of software and computer design**

  • Name a major historic trend in computer electronic circuitry.
  • What is the central historic trend in how computers are physically built?
  • What is one of the important algorithm-execution trends as computers evolved during their long history?
  • What was the first commercially-available computer programming language?

When reading through all the resources for 1a, I didn’t see mention of algorithm-execution trends? Am I missing something? The word execution isn’t even on The History of Programming Languages.

Same goes to the rest of the problems listed here, they seem vague and my response could be completely wrong. Any push in the right direction would be appreciated.
