Answer 2

Explanation:

Answer: B. In a mesh topology, each device is connected directly to every other device on the network. Such a structure requires that each device have at least two network connections. The mesh topology is not commonly implemented. In a bus topology, each device is connected to the network through a single connection. In a ring topology, each device is connected to the network through a single connection. In a star topology, each device is connected to the network through a single connection.

Answer D. The layout of the network is referred to as the topology. The logical topology defines how the devices connected to the network see it, and the physical topology defines how the network is actually laid out. The term backbone is used to describe a segment of the network that acts as a connection point for other segments. Network is a generic term used to describe the network as a whole. The term physical map is not commonly used.

Answer: A. In a mesh topology, all devices are connected directly to every other device on the network. If one link fails, there is always another available. It is the most fault-tolerant network topology. A hierarchical star is a variation of the standard star and is not considered a fault-tolerant implementation. A ring topology is not considered fault tolerant. In a star topology, each device is normally connected to one central device and therefore is not fault tolerant.

Answer C. The most widely implemented mesh topologies are the Internet and the telephone network.

Answer B. Because workstations don't contend for access to the network, access is guaranteed with a token ring network. IP addressing is a Network layer concept and isn't dependent on a Data Link layer protocol or topology. Token ring may be implemented in full-duplex, but at the workstation level, it isn't common. A ring must be broken to add a new workstation.
