Step 1: Definition of cookie.
A cookie is a small text file stored on the client’s computer by the web browser at the request of a website. It helps the website remember user preferences, login sessions, or other small pieces of data.
Step 2: Analyze options.
- Option 1: Incorrect → The cookie is stored on the client’s computer, not the server’s.
- Option 2: Correct → Only the website that set the cookie can read/modify it, and it is stored on the client system.
- Option 3: Incorrect → Cookies are not created manually by users; they are generated by websites.
- Option 4: Incorrect → Cookies are not security systems, though they may store authentication tokens.

Step 3: Clarification.
Cookies improve user experience by remembering session states, shopping carts, and preferences. They are not inherently secure, and misuse can lead to privacy issues.
