What is Chronological Order?
Chronological order means sorting a list of items according to a date or time associated with each item.
For example, file managers typically allow you to sort files in a folder in chronological order according the "creation date" of the file, meaning that files created more recently will be displayed first and the oldest files will be displayed last, or vice-versa. Similarly, you can sort by "modification date."
On the Internet, a feed of posts is typically sorted in chronological order. To do this sort, a sorting algorithm is used. This can be a bit confusing because when a feed on social media is in any order EXCEPT chronological order, we say the social media has "an algorithm," (The Algorithm) in reference to a recommendation algorithm that prioritizes certain posts over others.
