Network Protocols Standard List
A port is a logical component that identifies a specificprocess or a network service. Ports are identified for each protocol andaddress combination by 16-bit unsigned numbers, commonly known as the portnumber. The most common protocols that use port numbers are the TransmissionControl Protocol (TCP) and the User Datagram Protocol (UDP).
A port number is always associated with an IP address of a host and the protocol type of the communication. It completes the destination or origination network address of a message. Specific port numbers are commonly reserved to identify specific services (Standardized), so that an arriving packet can be easily forwarded to a running application. For this purpose, the lowest numbered 1024 port numbers identify the historically most commonly used services, and are called the well-known port numbers. Higher-numbered ports are available for general use by applications and are known as ephemeral ports.
