Topology: The failed connection may disable the whole network If the drop-lineįails, only the corresponding device cannot operate. Transmission stops if the failure is in the bus. Which has the failed connection to the hub. To send data through the hub there will be no access to the device Star topology: The other devices will still be able Topology: If one connection fails, the other connections will stillīe work-ing. Number of ports: (n 1) = 5 ports needed per device 17. With 16 bits, we can represent up to 216ĭifferent colors.

The general factors are size, distances (covered by the network), structure, and ownership. The number of cables for each type of network is: a. We give an advantage for each of four network topologies: a. In half-duplex transmission, only one entity can send at a time in a full-duplex transmission, both entities can send at the same time. We can divide line configuration in two broad categories: a. Line configurations (or types of connections) are point-to-point and multipoint. Advantages of a multipoint over a point-to-point configuration (type of connec- tion) include ease of installation and low cost. The three criteria are performance, reliability, and security. The advantages of distributed processing are security, access to distributed data- bases, collaborative processing, and faster problem solving. The five components of a data communication system are the sender, receiver, transmission medium, message, and protocol. 1 CHAPTER 1 Introduction Solutions to Review Questions and Exercises Review Questions 1.
