Detailed explanation-1: -HTTPS is secure and is on port 443, while HTTP is unsecured and available on port 80. Information that travels on the port 443 is encrypted using Secure Sockets Layer (SSL) or its new version, Transport Layer Security (TLS) and hence safer.

Detailed explanation-2: -HTTPS over port 443 is used for the transmission of secured traffic, thus creating a secure communication channel between the client browser and the server it wants to connect to.

Detailed explanation-3: -Port 443. The Internet Engineering Task Force (IETF) recognizes the TCP port number 443 as the default HTTPS protocol. It provides an encryption algorithm for exchanging information between web servers and browsers. HTTPS port 443 works by securing network traffic packets before the data transmission occurs.

Detailed explanation-4: -By default, HTTPS connections use TCP port 443. HTTP, the unsecure protocol, uses port 80.
