What is Cloud Computing?

Cloud computing ka matlab hai — data aur software ko internet ke zariye access karna, instead of installing or storing it on your local computer.

Matlab:
No physical hard drive or server needed
Aap apna data, software ya service kisi remote data center (cloud) se use kar sakte ho — bus internet hona chahiye.

Simple Real-Life Examples:

• Google Drive: Aap apne files cloud me store karte hain aur kahin se bhi access kar sakte hain.

• Netflix: Aap movies stream karte ho bina download kiye. Sab kuch cloud server se aa raha hota hai.

• Gmail: Emails, attachments — sab kuch cloud me stored hai.

1. Aap ek cloud platform se connect hote ho (like Google Cloud, AWS, or Microsoft Azure)

2. Aapko ek remote server allocate kiya jata hai

3. Aap wahan se data access karte ho, run karte ho apps, aur even websites host karte ho

4. Data internet ke through transfer hota hai — fast and encrypted
