Which protocol is used for secure communication between web browsers and servers?
- HTTP
- FTP
- HTTPS
- SMTP
Answer: HTTPS
HTTPS (HTTP Secure) encrypts data using SSL/TLS to protect confidentiality and integrity during transmission. Essential for login pages, payments, and sensitive data. HTTP transmits in plaintext. Browsers mark non-HTTPS sites as 'Not Secure'. Fundamental for web security awareness in all government exams.
