receivers must continually monitor the messages going on around it and record anything that is addressed for the node. This method of networking probably seems unnecessarily complex, but as noted, it was the rst type of computer network developed and its de ciencies were targeted when other types of networks were developed. The star network (Fig. 1.27) improves on the basic single-media network by linking all the nodes to a single switch ( Sw in Fig. 1.27), which is responsible for directing messages between nodes (directly from the transmitter to the receiver). The addition of the switch allows multiple messages to be passed simultaneously between nodes. If you access a cabled Ethernet network, this is the topology that is used. Many networks use a router instead of a switch for passing messages back and forth, and the difference between the two is that a router will determine the best path for a message (including passing it along to other networks). If you have a cable modem at home, you probably have a router to pass data between computers in your home as well as out to the Internet if it is required. By providing a direction connection from each node to the switch, the star network allows much faster data transmission along with less unnecessary traf c to the various nodes compared to the single-media network.

The ring network (Fig. 1.28) endeavors to avoid the collision issue by passing a token, which can have a message attached to it. Computers only transmit onto the ring network if the token is empty when it comes to them. If there is a message attached to the token, the computer must strip it and transmit an empty token in its place. Message transmission is quite ef cient although there is a major drawback to this network topology: if one node fails, the entire network is brought down. Despite this disadvantage, ring networks are used in some telecommunications applications. Supercomputers made up of multiple processors and high performance server farms provide multiple network connections from each node to, ideally, every other node in the network, as shown in Fig. 1.29. This topology is known as a mesh network. It avoids the issues of possible message collisions by having each node specify where each message is going. The obvious disadvantages of this topology are the cost of having multiple network adapters on each node as well as the wiring complexity between each node. It is impossible to provide a connection between each node when there are more than four or ve nodes in a mesh, so there has been a great deal of research done on designing the optimal mesh con gurations (often consisting of meshes of meshes) for supercomputers or servers built from thousands of microprocessors. There really is no need for mesh networking when working with embedded microcontrollers. Large networks, such as the Internet, are usually called hybrid networks because they are built from smaller networks of varying topologies as shown in Fig. 1.30. The interconnections between the smaller networks and the large hybrid are usually through bridges (connections between two dissimilar network connections) or routers (when the connections are the same). Finally, I want to discuss universal serial bus (USB) adapters, as they are common applications for embedded microcontrollers like the PIC MCU. While you may be most
