Explanation:
I could not find the examples that are missing but I will tell you something more about the term ''computer literate'' so you can find it by yourself.
- Computer literacy is considering the knowledge, skills and ability to use technology in the most advanced way. The person who is computer literate has ability of computer programming, problem solving and all of the skills related to computers. They are understanding and researching how the computers are working and operating.
This term was found in the early 70s by Andrew Molnar.
