Description: A virtual port is a fundamental concept in network communication, defined by software, that allows interaction between different applications and services over a network. Unlike physical ports, which are tangible connections on a device, virtual ports are abstracted and managed by the operating system or network software. These ports are identified by numbers ranging from 0 to 65535, with each one potentially assigned to a specific service, such as HTTP (port 80) or FTP (port 21). The main feature of virtual ports is their ability to allow multiple simultaneous connections through a single IP address, thus facilitating communication between different applications and users. This is especially relevant in server environments, where multiple services can operate at the same time without interfering with each other. Additionally, virtual ports are essential for implementing network protocols, allowing data to be sent and received efficiently and in an organized manner. In summary, virtual ports are a key tool in modern network architecture, providing flexibility and scalability in digital communication.
