What purpose does a "function" serve in a programming language?

What primary purpose does the netmask serve within a local area network?
The primary purpose of the netmask is to define the range of addresses that are part of the local area network. When attempting to communicate with another device whose address fits within the defined mask, the given device will attempt to communicate directly. However, if the target device has an address that does not reside within the defined mask, it will instead attempt to use the defined gateway as a relay for said communications.
