Picture visiting your favorite bakery. After making a few purchases, the baker, familiar with you as a regular customer, takes note of your most frequent orders. Consequently, every time you arrive, he has your usual items prepared. This is similar to how web cookies function. They are small files that a website saves on your computer to retain information about you, such as your login details or the contents of your shopping cart, which enhances the personalization and efficiency of your experience on the site.
