====== Process (Host) ======

In networking terms, the word //process// refers to that part of a [[application|network application]] which executes within the memory of a [[host]] (or [[end-system]]). In order for two processes to communicate with each other, each process must have a unique address on the the [[network]]. The host itself will be uniquely identified by its [[ip_address|internet address]]; each process has its own identifier which is called a [[port number]]. The port number is assigned to the [[socket]] through which the two processes communicate.
