Data transfer rate (also called bandwidth)
node speed
Essentially, any packet transmitted between ports on the switch behave as though the two connected nodes were directly connected as the only two nodes on the network, thus avoiding packet collisions with other nodes.

Transmission media
Data packets are the units of data that are exchanged between nodes on a network. A typical packet contains around 1,000 to 1,500 bytes.
Whats is the relationship between a sub network a node?
A lower speed network such as a 10BaseT network can handle 1024 devices per segment; that is not the limitation on the entire network.
