Searching and sorting are fundamental ways to organize and locate information in a collection of data. Searching means looking through each piece of data until you find what you’re after; sorting means arranging items in a specific order (like smallest to largest or A to Z) so that later tasks—especially searches—become much quicker to perform. Computers carry out these tasks by following precise step‑by‑step procedures called algorithms, which ensure consistent, repeatable results.

Every collection of items—whether names, numbers, or objects—can benefit from being sorted or searched efficiently, saving time and resources in any program that needs to handle data.
