Question

What are the two protocols for communication on Internet and how they come into play when u visit a website?

Answer 1

Two protocols are HTTP and HTTPS depending on the site. If it is secure, then you utilize HTTPS which is usually 143. HTTP is 80.

There really isn't anything to HTTP but HTTPS does require a certificate. As a user, you go and verify their certificate by sending information using a public key. They use their private key to decrypt it. This way it ensures any information transmitted cannot be intercepted and read by a third party.
