What are Internet Cookies?

Internet cookies, often simply referred to as “cookies,” are an integral part of the web browsing experience, offering both convenience and a point of privacy consideration. This article delves into the various aspects of cookies, elucidating their function, types, uses, and the privacy concerns they raise.

What are Internet Cookies?

Understanding the Basics of Cookies

Cookies: Small Data Files with Big Impact

Cookies are small text files that websites send to a user’s device while they are browsing the internet. These files, which are stored on the user’s device, enable websites to remember information about the user, enhancing their browsing experience.

Types of Cookies and Their Functions

Session Cookies: Temporary Convenience

Session cookies exist only during an internet session and are deleted once the browser is closed. They play a crucial role in ensuring a smooth browsing experience, facilitating functions like maintaining items in a shopping cart during online shopping.

Persistent Cookies: Memory Beyond Sessions

Unlike session cookies, persistent cookies remain on a user’s device even after the browser is closed. They are used by websites to remember a user’s preferences, login details, and other customizations for future visits.

First-Party vs. Third-Party Cookies

First-party cookies are set by the website a user is visiting, while third-party cookies are set by a domain other than the one being visited. Third-party cookies are typically used for tracking and advertising purposes, allowing advertisers to monitor a user’s browsing habits across multiple websites.
