== Ports in Networking ==
In an [[IP]] [[network]], a ''port number'' is used to identify a network service, which allows one physical computer to listen to various protocols at the same time. The possible range for port numbers is 1 to 65535. This divides up into:
1-1024 [[well known port]]s
1024-49151 [[registered port|registered]] and [[unregistered port|unregistered]] ports
49152-65535 [[private port|private]] (or dynamic) ports
=== Well Known Ports ===
The [[well known port]]s are ports between 0 and 1024, assigned by the [[IANA]] and on most systems can only be used by system (or [[root]]) processes or by programs executed by
privileged users.

Definition[edit]
port
- a place (seaport or airport) where people and merchandise can enter or leave a country
- sweet dark-red dessert wine originally from Portugal
- an opening (in a wall or ship or armored vehicle) for firing through
- interface: (computer science) computer circuit consisting of the hardware and associated circuitry that links one device with another (especially a computer and a hard disk drive or other peripherals)
Ports in Networking[edit]
In an IP network, a port number is used to identify a network service, which allows one physical computer to listen to various protocols at the same time. The possible range for port numbers is 1 to 65535. This divides up into:
1-1024 well known ports
1024-49151 registered and unregistered ports
49152-65535 private (or dynamic) ports
Well Known Ports[edit]
The well known ports are ports between 0 and 1024, assigned by the IANA and on most systems can only be used by system (or root) processes or by programs executed by privileged users.
To the extent possible, these same port assignments are used with the UDP (RFC 768).
