What are Cookies on the Internet?
Simply put, cookies are small text files that websites create and store on your device. These files contain information about your browsing history, preferences, and settings. Each time you visit a website, its server checks your device for any cookies related to that website. If found, these cookies allow the website to “remember” you and tailor its content and services to your interests.
Types of Cookies
There are numerous types of cookies, each serving a specific purpose:
Session Cookies
Session cookies are temporary files that are only stored in your device’s memory during the duration of your browsing session. They are deleted automatically when you close your browser. Session cookies are often used to keep track of your items in a shopping cart or to facilitate secure online transactions.
Persistent Cookies
Persistent cookies remain on your device for a predetermined period, typically several days or even months. They are not deleted when you close your browser and allow websites to remember your login information, preferences, and other settings across multiple visits.
First-Party Cookies
First-party cookies are created by the website you are currently visiting. These cookies allow the website to remember your preferences, such as language, time zone, and font size, making your browsing experience more personalized.
