Bubble Sort is a simple sorting algorithm used in software development to arrange elements in a specific order, typically from smallest to largest. It works by repeatedly comparing adjacent elements and swapping them if they are in the wrong order. This process is repeated until the entire list is sorted. Think of it like arranging a shelf of books by repeatedly comparing and swapping books until they are sorted by title from A to Z. While Bubble Sort is easy to understand, it may not be the most efficient sorting algorithm for large datasets.
