Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which protocol is used for secure connections to websites?
A
IP
B
TCP
C
HTTP
D
HTTPS
Explanation: 

Detailed explanation-1: -HTTPS uses an encryption protocol to encrypt communications. The protocol is called Transport Layer Security (TLS), although formerly it was known as Secure Sockets Layer (SSL).

Detailed explanation-2: -HTTPS is HTTP using SSL/TLS security. SSL/TLS typically runs on top of TCP, but there is nothing to stop you from running it on UDP, SCTP or any other transport layer protocol. As a matter of fact HTTPS over TCP and UDP are both defined as “well known” by IANA and have reserved port numbers.

Detailed explanation-3: -HTTPS: What are the differences? HTTPS is HTTP with encryption and verification. The only difference between the two protocols is that HTTPS uses TLS (SSL) to encrypt normal HTTP requests and responses, and to digitally sign those requests and responses. As a result, HTTPS is far more secure than HTTP.

Detailed explanation-4: -Hypertext Transfer Protocol Secure (HTTPS) is a protocol that secures communication and data transfer between a user’s web browser and a website. HTTPS is the secure version of HTTP. The protocol protects users against eavesdroppers and man-in-the-middle (MitM) attacks.

Detailed explanation-5: -A secure URL should begin with “https” rather than “http.” The “s” in “https” stands for secure, which indicates that the site is using a Secure Sockets Layer (SSL) Certificate. This lets you know that all your communication and data is encrypted as it passes from your browser to the website’s server.
