What port number is associated with HTTP?

  1. Port 80

  2. Port 90

  3. Port 8080

  4. Port 443

The correct answer is: Port 80

The port number associated with HTTP is 80. This is a well-known port typically used for unencrypted web traffic. When a web browser accesses a website using the HTTP protocol, it by default connects to this port unless specified otherwise. This convention helps standardize communications on the internet, allowing servers and clients to recognize where to send and receive data. Ports like 90 and 8080 can also be used for web traffic, but they are not the default. Port 443, on the other hand, is specifically associated with HTTPS, which is the secure version of HTTP, using encryption to protect the data exchanged between the server and client. Understanding the significance of these ports is crucial for anyone working within network or web security, as it aids in configuring firewalls and correctly routing internet traffic.
