A) Storing user data

The primary purpose of cookies in web browsing is to store and manage information on a user’s device as they interact with websites. Cookies are small text files that web servers send to a user’s browser and are then stored on the user’s computer or mobile device. They serve several important purposes:

  1. Session Management: Cookies can be used to maintain a user’s session when interacting with a website. They help websites remember information about the user as they navigate from page to page, ensuring a seamless and personalized experience.
  2. User Authentication: Cookies are often used to keep users logged in to websites and remember their login credentials. This allows users to access their accounts without repeatedly entering their username and password.
  3. Personalization: Cookies help websites remember user preferences and settings, such as language, theme, and layout choices. This enables a more customized browsing experience.
  4. Shopping Carts: E-commerce websites use cookies to maintain shopping cart contents, allowing users to add items to their cart and continue shopping or proceed to checkout without losing their selections.
  5. Tracking and Analytics: Cookies are used for tracking user behavior on websites. This data is valuable for website owners and marketers to analyze site performance and user engagement, enabling them to make improvements.
  6. Targeted Advertising: Advertisers and marketers use cookies to track user interests and display targeted advertisements based on a user’s browsing history and preferences. This is often part of the practice known as “online behavioral advertising.”

It’s important to note that while cookies are essential for many website functionalities, they have raised privacy concerns. Some users are concerned about the potential for tracking and privacy invasion, which has led to increased regulation and the development of browser features that allow users to manage and block cookies selectively.

In response to privacy concerns, web standards and regulations have evolved, and mechanisms like SameSite attribute, Secure attribute, and HTTP-only attribute in cookies have been introduced to enhance user control and security. Users can also adjust their browser settings to manage or block cookies, giving them more control over their online privacy.
