What Are Browser Cookies?
Cookies are a collection of data that contains activity on a site. All this activity data will be saved to your computer. Then it will be sent back to the place you previously accessed.
An easy example is when logging in on social media such as Facebook or Instagram. When logging in, a password remembers notification will appear.
When you give the Remember Password permission, the login username and password will be stored on the computer, and you can use them again.
