Today, I will explain to you that the biggest difference between these two ports lies in their different services:

Port: 80

Service: HTTP

Description: for web browsing. Wood ma Executor opens this port

Port: 443

Service: Https

Description: Web browsing port, can provide encryption and transmission through a secure port of another kind of HTTP.

Port 443 is the web browsing port, which is mainly used for HTTPS services and is another kind of HTTP that provides encryption and transmission through secure ports. HTTPS services are used in some websites with high security requirements, such as banks, securities, shopping, etc., so that the exchange of information on these sites, other people grab the bag to get encrypted data, to ensure the security of the transaction. The address of the web page starts with https://, not the usual http://.

Port 80 is open for HTTP (HyperText Transport Protocol), the hypertext transfer protocol, which is the most frequently used protocol for surfing the Internet, and is mainly used for WWW (World Wide Web), the protocol for transmitting information on the World wide Web. You can access the site by adding ": 80" to the HTTP address, because the default port number for web browsing services is 80, so you only need to enter the URL instead of ": 80".

HTTPS (Secure Hypertext Transfer Protocol) secure Hypertext transfer Protocol is a secure communication channel developed based on HTTP for exchanging information between client computers and servers. It uses secure Sockets layer (SSL) for information exchange, which is simply the secure version of HTTP.

The difference between HTTPS and HTTP:

Https agreement needs to apply for a certificate from ca. Generally, there are few free certificates and a fee is required.

Http is a hypertext transfer protocol, information is plaintext transmission, and https is a secure ssl encrypted transmission protocol.

Http and https use completely different connections and different ports, the former being 80 and the latter 443.

The connection of http is very simple, the stateless HTTPS protocol is built by SSL+HTTP protocol, which can be encrypted and authenticated. The network protocol is more secure than http protocol.
