Workstations are called such because they typically do have a human user which interacts with the network through them. Services provided can include printing and faxing, software hosting, file storage and sharing, messaging, data storage and retrieval, complete access control (security) for the network's resources, and many others. Servers are generally not used by humans directly, but rather run continuously to provide "services" to the other computers (and their human users) on the network.
