- There are many methods for exchanging information between networked devices
- One fundamental way of differentiating networking technologies is on the basis of the method they use to determine the path between devices, over which information will flow
- In simplified terms, there are two approaches:
- either a path can be setup between the devices in advance
- or the data can be sent as individual data elements over a variable path
