Question 2 Level 2 - Input, Processing and Output

Which of the following is an example of an output from a computer system? (select the most correct answer)

  1. Taking a photo on your smartphone’s camera

  2. A text message being typed into a messaging system

  3. A video being uploaded to YouTube

  4. One of your friends’ posts on a social media site

D is the most correct

This is actually a very tricky question, because all of the above have elements of output, but the input aspect is being emphasised in the descriptions. D is the most correct answer as it does not also involve input.
