Understanding Cookies in the Digital World

When you visit a website for the first time, a unique identifier or "cookie" is created and stored in your browser. This helps the website recognize you on future visits, preventing repetitive tasks like logging in repeatedly. Cookies are often set by the domain (or website) you are visiting, known as first-party cookies, or by third-party domains, to help deliver ads and analyze visitor behaviour.

Websites such as YouTube and Google use cookies to provide personalized advertising experiences and video recommendations. When you watch embedded videos or use a Google account, cookies can enhance your experience by saving your history and optimizing content recommendations.

2.

Persistent Cookies: Unlike session cookies, persistence cookies remain on your device for a specified duration or until manually deleted. They help remember settings and information for future visits, such as sign-in credentials.
