What is the difference between a Cookie and a Session?

In the context of web development, cookies and sessions are both used to store information on the client side, but they differ in their functionality and scope:

• Cookie: Cookies are small pieces of data stored on the client's browser. They are used to persistently store information, such as user preferences or shopping cart items. Cookies have an expiration time and can be read on subsequent visits to the website.
• Session: Sessions are server-side storage mechanisms that store user-specific information temporarily. A session is created when a user logs in to a website and is destroyed when the user logs out or closes the browser. Sessions are typically more secure than cookies as the data is stored on the server.

Overall, cookies are suitable for storing small pieces of data that need to persist across visits, whereas sessions are better for managing user authentication and temporary data.
