P2P, often known as a workgroup, is a computer network (see Figure 1.8) in which hosts do not have predefined roles. Instead, they change roles from client to server, and vice versa, based on their actual activities on the network. For example, if PC1 is requesting resources from PC2, then PC1 acts as the client and PC2 acts as the server. If PC2 requests resources from PC1, then PC2 acts as a client and PC1 acts as the server. Usually, PANs represent the best examples of P2P computer networks:
