A network’s physical topology is the layout in
which its computers, printers, and other devices
are arranged.
• A network’s access method specifies how data is
transmitted from node to node across the
network, and its transmission media are the
communication media.
• These three characteristics help define a
network’s throughput – that is, the amount of
data that can be transferred from one node to
another node in a specified amount of time.
