One group known today than saying we explain the two biggest difference lies in the different port services:
Port: 80
Services: HTTP
Description: for web browsing. Wood ma Executor open this port
Port: 443
Services: Https
Description: Web browser port, can provide encryption and transmission through the secure port to another HTTP transmission.
443 port Web browser that the port was mainly used for HTTPS service is to provide encryption and secure HTTP port by another transmission. In some of the higher security requirements sites, such as banking, securities, shopping, etc., are used HTTPS service, so that the exchange of information on these sites, others capture the acquired data is encrypted to ensure the security of transactions . Web address with https: // to start, instead of the usual http: //.
80 port is open for the HTTP (HyperText Transport Protocol) Hypertext Transfer Protocol, which is used most often surf the Internet protocol, mainly used for WWW (World Wide Web) protocol that is the World Wide Web to transfer information. Via HTTP address (that is often said that the "URL") plus ": 80" to access the website, because browsing the web service default port number is 80, so just enter the URL, do not enter ": 80" was.
HTTPS (Secure Hypertext Transfer Protocol) which secure hypertext transfer protocol is a secure communication channel, which is based on the development of HTTP, is used between the client and server exchange information. It uses Secure Sockets Layer (SSL) to exchange information, in short, it is a safe version of HTTP.
HTTPS and HTTP difference:
ca https protocol needs to apply for a certificate, the certificate is generally free little need to pay.
http hypertext transfer protocol, information is transmitted in the clear, https is encrypted with a security ssl transfer protocol
http and https using a port different connections are not the same with the former 80, which is 443.
Http connection is simple, stateless protocol HTTPS is constructed from SSL + HTTP protocol can be encrypted transmission, network authentication protocol than http protocol security
