What is Cookies in Website?
In simple terms, cookies are small text files that websites store on your computer or mobile device through your browser. These files contain information about your activity and preferences on that website.
For example, if you add a product to a shopping cart and leave the site, cookies help the website remember your cart when you return. Technically, these are called HTTP cookies or web cookies.
Analogy: Think of cookies like a token or slip given at a restaurant counter. When you return with the slip, the restaurant knows what you ordered. Similarly, cookies help websites recognize returning visitors.
How Do Website Cookies Work?
Here’s how cookies function step-by-step:
- You visit a website.
- The website sends a small file (cookie) to your browser.
- The cookie stores data like user ID, session ID, or preferences.
- When you return, the browser sends that cookie back to the server.
- The server reads the cookie and personalizes your experience.
This process allows the website to “remember” you, your settings, and even what’s in your cart.
Types of Website Cookies (Explained Simply)
There are various types of cookies, each serving a specific purpose:
| Type | Description | Lifespan | Example |
|---|---|---|---|
| Session Cookies | Temporary cookies that expire when you close your browser | Temporary | Login session |
| Persistent Cookies | Remain on your device for a set time even after closing the browser | Fixed duration | Remembering login, preferences |
| First-party Cookies | Set by the website you are visiting | Website-specific | Language settings |
| Third-party Cookies | Set by other domains (ads, analytics) | Cross-site | Tracking user behavior |
| Secure Cookies | Transmitted over HTTPS only for security | Depends on type | Sensitive login sessions |
| HttpOnly Cookies | Cannot be accessed via JavaScript | Depends on type | Protect from cross-site scripting |

Websites use cookies to provide a smoother, personalized experience:
- Save user preferences (e.g., theme or language)

Without cookies, websites would forget who you are as soon as you leave the page.
