HTTPS. HTTPS is the secure version of HTTP and uses SSL/TLS for encryption. It protects sensitive data like passwords and credit card numbers during transit. Websites with HTTPS are verified by digital certificates issued by trusted authorities.

Question 3

In the TCP/IP model, which protocol is responsible for logical addressing and routing packets across different networks?
