Conventionally, an HTTP server listens on port 80. Regardless of the brand of web server that you are running, the server will typically listen for HTTP traffic on port 80 and HTTPS traffic on port 443.
There are services running on this web server that are using well known port numbers. UDP port 53 is used for DNS, TCP port 80 is used for non-encrypted web services, and TCP port 443 is used for encrypted web services.
Port 80 is usually used for an HTTP server.
A server will usually listen on port 80 for web connections. This is the default port used for browsing websites and Surfing.
No. By default, FTP servers are set to listen at TCP port 23. In contrast, HTTP/web servers listen at TCP port 80.
Port 8080 is an alternative to the port 80 used by http and web services. History: The Internet was largely born on UNIX-based systems and servers. UNIX enforces the notion of the first 1023 "privileged ports" which can only be opened by services running with so-called "root", or administrative, privileges. Historically, this meant that only authorized system administrators were able to establish and operate a web server on port 80 since this was within the first 1023-port privileged region. Therefore, when non-administrators wished to run their own web servers on machines which might already have a server running on port 80, or when they were not authorized to run services below port 1024, port 8080 was often chosen as a convenient place to host a secondary or alternate web server.
If I understand the question aright; different port numbers are used to identify different protocols. Port numbers between 1 and 1023 are well-known numbers and standards define which protocol uses which. FTP uses port number 21, HTTP uses port 80.

A Web server - or most other servers - will HAVE TO reserve a port number, to function correctly. For a Web server, this is usually port 80, but this can be changed to any other port.A Web server - or most other servers - will HAVE TO reserve a port number, to function correctly.

Port 80 and port 44 are located inside the server and mainly Port 80 is used by server transactions of HTML pages to the web browser. thanks

Port 80 is the default web server port and IIS would use Port 80 unless configured to use a different port.
The firewall typically is configured to allow inbound connections on a specific port to a particular IP address on the network (the server). This usually means that port 80 and/or 443 will be configured to allow access to the server from the Internet.
1) On the server side, to distinguish different applications. Thus, if the server (the server computer) receives a data packet for port 80, it will usually be forwarded to the Web server; but if it receives a data packet for port 21, it will be forwared to the FTP server. 2) On the client side, to distinguish different conversations. For example, if the browser accesses two files from the same Web server at the same time, the first file might be assigned, for example, port 1024 (for the sending port; the receiving port will be 80), while the next file might be assigned port 1025. When a data packet is sent back for port 1025, in this example the browser knows that it is for the second file.

Port 80 is used only for the initial connection. As soon as a host connects, the server hands off the session to a free port and the session is established using that port. This keeps port 80 free for new incoming requests.

If a network address is thought of as a physical address for a building then a port would be a room within the building. THe function of a port is to allow software to listen for or send out communication that is specifically related to it's function. For example, most internet (http) traffic is on port 80, FTP (File Transfer Protocol) sends and listens on Port 21, other services use other ports. This allows a single computer with a single IP address to be both a web server and a file server.
