Computer Tips - What is sorting ascending vs descending?

Date: 2015feb1 Q. What is sorting ascending vs descending? A. Ascending is the regular way of sorting - eg A to Z or 0 to 9. Going up. And Descending is the opposite. Going down. For letters and numbers its pretty obvious but what about file modify times. When they are sorted descending the most recent is first (since its the largest number).
