HTTP Port 80 is the default port for HTTP (Hyper Text Transfer Protocol) communications. It indicates that utilizing this port, unencoded data is sent between the user's browser and the server. This port is associated with TCP (Transfer Control Protocol). Thus, when using TCP, if you want to send data to a certain port, it must first be encoded in some way as either text or binary.
The reason that this port is default and not another number is because most browsers use it by default. If someone were to type a different port into their browser, it would be difficult for websites to recognize which port to send data to. Using default ports makes it easier for users.
This port was originally intended to support file transfers between browsers on the same computer. However, due to security issues with other ports, this port has become reserved for use in web applications.
Browsers use port 80 because it is the default port for HTTP. Other protocols can also be used but they must be specified when creating connections. For example, if I wanted to connect to Google's search engine at http://www.google.com/search?q=hello+world I could do so by typing http://www.google.com/search? Q=hello+world into my browser's address bar. The default port for HTTP is 80 so that is what I need to specify when connecting to a website.
HTTP port 443 is a popular alternate HTTP port for online traffic. Also also TCP ports 80, 81, and 8443. It is also suitable for HTTP Web Proxies. For remote management, some broadband routers operate a web server on port 8080. This is used by management tools to allow users to configure their devices from a computer browser.
The port number 80 is designated for HTTP. Port 8080 is commonly used for a personally hosted web server when the ISP limits this sort of usage for non-commercial clients. The default second choice for a webserver is port 8080. For FTP, the standard port number is 21.
Port 8080 is a typical proxy and caching port. It is also outside the range of the service port. Unencrypted HTTP traffic is routed over port 80, whereas encrypted HTTPS traffic is routed through port 443.
The Transmission Control Protocol is used by TCP port 8080. TCP is one of the most common protocols used in TCP/IP networks. TCP is a connection-oriented protocol that necessitates handshaking to establish end-to-end communication. This handshake allows for error checking and confirmation of successful connection establishment.
The HTTP protocol via TLS/SSL is accessed through port 443/HTTPS. Port 80/HTTP is used by the World Wide Web. If web servers are being hosted, incoming connections to those web servers will be permitted. Protecting these servers against denial of service attacks is a common practice.

Web servers, for example, frequently utilize port 80. However, it is changeable by a web server administrator. Assigning port 8080 to a web server is the most popular case. To send traffic to this web server, attach the port number to the end of the domain name, for example, http://websitename.com:8080. This means that all requests must be sent to http://websitename.com:8080/.
The 8080 port was originally assigned to a DEC research project called "Packet Internet Mail". It was later adopted by Vinton Cerf and others for use with TCP/IP. Today, most websites use this port because it's usually not used by anything else important or necessary.
There are actually two different ports named "8080", one in the 10,000 series and another in the 8000 series. These ports were never intended to be used simultaneously on the same computer or network. One port can be used while the other port is being used by something else. However, this isn't commonly done because many programs won't work properly if both ports are in use at the same time.
Here are some applications that often use the 8080 port:
Web servers - such as Apache HTTP Server, Lighttpd, nginx, etc.
Mail servers - such as Postfix, Exim, qmail, etc.
