The first and last addresses in a TCP/IP subnet are reserved (not for use for your devices). The former identifies the "network", while the latter is used to send broadcasts to everyone. Suppose you're using 192.168.1.x addresses. .0 represents the network and .255 is the broadcast address. This assumes a 255.255.255.0 subnet mask. Change that and the network/broadcast addresses change as well.
In networking, a "node" is a device that connects to the network. For example, a PC, printer, server, PLC, router, etc.

Please define network and broadcast with respect to either bit assignment or eitherwise. Node from a design point of view, should remain the gate to open. Beyond that, it is quite another story.
Please rectify me if I am wrong on this subject.
