This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.

MacPorts stores the instructions required to build a port in a port description file, otherwise known as a portfile. [55] This is similar to how the AUR use shell scripts known as a PKGBUILD, [ 56 ] or how Homebrew use ruby scripts as a formula. [ 57 ]
An ephemeral port is a communications endpoint of a transport layer protocol of the Internet protocol suite that is used for only a short period of time for the duration of a communication session. Such short-lived ports are allocated automatically within a predefined range of port numbers by the IP stack software of a computer operating system.
In January 2010, a package manager was introduced for the Node.js environment called npm. [18] The package manager allows programmers to publish and share Node.js packages, along with the accompanying source code, and is designed to simplify the installation, update and uninstallation of packages.

In computer networking, a port or port number is a number assigned to uniquely identify a connection endpoint and to direct data to a specific service. At the software level, within an operating system , a port is a logical construct that identifies a specific process or a type of network service .
NPM may stand for: Organizations. National Postal Museum (since 1993), a museum in Washington, D.C., United States; National Palace Museum, a museum in Taipei ...
In contrast, a port which rejects connections or ignores all packets directed at it is called a closed port. [ 1 ] Ports are an integral part of the Internet's communication model — they are the channel through which applications on the client computer can reach the software on the server .
