Cookies are small pieces of text sent to your browser by a website you visit. They are created by websites to remember information about your visit, which can make your online experience easier. For example, sites can keep you signed in, remember your site preferences, and give you locally relevant content. There are two types of cookies:

• First-party cookies: Created by the site you visit. The site is shown in the address bar.
• Third-party cookies: Created by other sites. A site you visit can embed content from other sites, such as images, ads, and text. Any of these other sites can save cookies and other data to personalize your experience.

Google Chrome allows you to manage cookies on a site-by-site basis. You can choose to delete existing cookies, allow or block all cookies, and set preferences for certain websites. If you delete cookies, you might get signed out of sites that remember you, and your saved preferences could be deleted. This applies any time a cookie is deleted.

In summary, cookies are small files created by websites to remember information about your visit, and they can make your online experience easier. Google Chrome allows you to manage cookies on a site-by-site basis, and deleting cookies can result in being signed out of sites that remember you and losing saved preferences.
