Understanding Network Ports and Their Role in Web Services

Network ports are numeric endpoints that let operating systems direct traffic to the correct service, with standard values like 80 for HTTP, 443 for HTTPS, 22 for SSH, and others such as 3306 for MySQL, enabling developers to configure custom ports while browsers often hide these defaults for user convenience.
