2. True or False A common way to share resources on a peer-to-peer network is by modifying the file-sharing controls via the computer’s operating system. Resource sharing is controlled by a central computer or authority. Clients on a client/server network share their resources directly with each other. Networks are usually only arranged in a ring, bus, or star formation and hybrid combinations of these patterns are not possible. Protocols ensure that data are transferred whole, in sequence, and without error from one node on the network to another. Every process that occurs during network communications can be associated with a layer of the OSI Model. Among the Session layer’s functions are establishing and keeping alive the communications link for the duration of the session, keeping the communication secure, synchronizing the dialogue between the two nodes, determining whether communications have been cut off, and, if so, figuring out where to restart transmission, and terminating communications. The primary function of protocols at the session layer is to translate network addresses into their physical counterparts and decide how to route data from the sender to the receiver. Addressing is a system for assigning unique identification numbers to devices on a network. Connectivity devices such as hubs and repeaters operate at the Presentation layer of the OSI Model.
