From the following statements, select all that correctly describe the client-based application architecture. Select one or more: a. In a client-based architecture, all portions of the architecture reside on the client computer. b. One fundamental problem with the client-based architecture is that it possible that far more data is transferred from the server to the client than is actually needed by the client. C. The significant advantages of the Client-based application architecture fueled the explosion of the use of personal computers. d. The reason why most applications today use the client-based architecture is that client-based applications can be easily purchased. e. In a client-based architecture, the presentation, application and data access logic all reside on the client computer. From the following statements, select all that correctly describe client-based architectures. Select one or more: a. One disadvantage of client-based architectures is that data stored on the server that needs processing must be transmitted from the server to the client. b. The server computer in a client-based architecture is responsible for the executing the data storage logic and data access logic. C. The server computer in a client-based architecture is responsible for executing the data storage logic. d architecture is responsible for executing only the application logic and presentation logic. Question 14 Complete 3.33 points out of 5.00 P Flag question Question 15 Complete 3.75 points out of 5.00 P Flag question Question 16 Complete signals is referred to as quality error. d. It is necessary to use a modem to transmit analog data over a digital circuit. e. One method used to reduce the difference between the digitized analog signal and the original analog signal is to increase the number of samples taken of the analog signal. From the following statements, select all that correctly describe the use of modula on in the analog transmission of digital data. Select one or more: a. Quadrature Amplitude Modulation (QAM) supports encoding 4 bits in each symbol for a total of 16 possible values. b. Using Phase Modulation, each 0 or 1 is represented by the number of waves per second present in the analog signal. c. Only Frequency Modulation and Phase Modulation support the encoding of more than one bit in a single symbol. d. There are three fundamental modula on techniques: Amplitude Modulation, Frequency Modulation, and Phase Modulation. e. The baud rate and the symbol rate both refer to the number of times per second the signal on the communication circuit changes. Select all statements that correctly describe multiplexing in the context of network communications. Select one or more: a. Using Statistical Time Division Multiplexing (or STDM), it is possible to provide different maximum speeds for different communication pathways multiplexed over the same physical circuit. b. If a physical circuit supports a maximum speed of 10 megabits per second, and multiplexing is used on that circuit to provide 4 independent communication pathways, the combined maximum speed of all 4 pathways is 40 megabits per second. C. Time Division Multiplexing (or TDM) divides the traffic for the virtual circuits by allocating specific time intervals for each virtual circuit's submission. d. Wavelength Division Multiplexing (or WDM) can be used to provide multiple virtual circuits over a single, physical fiber optic cable. e. Digital Subscriber Line (or DSL) can use multiple forms of multiplexing to transmit voice and data over network circuits.
