While IP addresses enable messages to go to and from specific devices, port numbers allow targeting of specific services or applications within those devices. Most ports are reserved for certain protocols - for example, all Hypertext Transfer Protocol (HTTP) messages go to port 80. Ports are standardized across all network-connected devices, with each port assigned a number. Ports allow computers to easily differentiate between different kinds of traffic: emails go to a different port than webpages, for instance, even though both reach a computer over the same Internet connection. Each port is associated with a specific process or service. Ports are software-based and managed by a computer's operating system.
