Which of the following is an example of an output from a computer system? (select the most correct answer)
Taking a photo on your smartphone’s camera
A text message being typed into a messaging system
A video being uploaded to YouTube
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.
Taking a photo is primary about input (the capture of light data coming through lens) but also involves output to the smartphone’s screen
A text message being typed in is clearly input, but also you can see the message being output on the screen as you type
A video being uploaded to YouTube is clearly input to YouTube, but is also output from your device.
A friend's posts on a social media site already exist so when you view them on your device that are purely output. Hence this is the most correct answer
