About port 80
Port 80 is mainly used so as to access a website. Many Internet Service Providers block incoming traffic to these ports before it reaches the users. Because of chances of malicious exploitation of these ports, it is considered to be dangerous to allow external users access it. Thus the blocking of incoming traffic can be an enforcement of ISP policies as well as a significant boon to ensure user security.
Role of port 80
Ports allow the clients to make a connection. The Windows media services and other programs make use of these ports for applications such as Remote Procedure Call(RPC) and Distributed Component Object Model(DCOM). If the allocated port range is not broad enough, then these applications would fail. Thus the port range must be such that it allows access to the applications. You can use this port to make the firewall configuration easier when accessing Windows media services.
Before you run any program on your PC you should see whether the port 80 is open or not. With the help of 'Netstat' command you can check if the port is open. Once the 'Zone' alarm has accessed the Internet you would be able to check whether the port 80 is open by giving the 'Netstat' command. Also, by starting the 'Report Manager' on a different computer, you can verify whether the port has opened correctly.
