What is Ports?

In computing, a port serves as a communication endpoint. At the hardware level, it's a physical interface (like a USB port) that connects devices. At the software level, particularly in networking, a port is a logical construct identified by a port number that allows different applications or services on a single machine to communicate with each other or with external systems. Well-known ports are standardized for common services like HTTP (port 80) and HTTPS (port 443).
