Chapter 4 Quiz

Which statement correctly describes frame encoding? It uses the characteristic of one wave to modify another wave. It transmits data signals along with a clock signal which occurs at evenly spaced time durations. It generates the electrical, optical, or wireless signals that represent the binary numbers of the frame. It converts bits into a predefined code in order to provide a predictable pattern to help distinguish data bits from control bits.

It converts bits into a predefined code in order to provide a predictable pattern to help distinguish data bits from control bits.

Match each type of frame field to its function. (Not all options are used.) addressing error detection type frame start

addressing -> This field helps to direct the frame toward its destination. error detection -> This field checks if the frame has been damaged during the transfer. type -> This field is used by the LLC to identify the Layer 3 protocol. frame start -> This field identifies the beginning of a frame.

Which method of data transfer allows information to be sent and received at the same time? full duplex half duplex multiplex simplex

full duplex

What makes fiber preferable to copper cabling for interconnecting buildings? (Choose three.) greater distances per cable run lower installation cost limited susceptibility to EMI/RFI durable connections greater bandwidth potential easily terminated

greater distances per cable run' limited susceptibility to EMI/RFI greater bandwidth potential

Which is a function of the Logical Link Control (LLC) sublayer? to define the media access processes that are performed by the hardware to provide data link layer addressing to identify which network layer protocol is being used to accept segments and package them into data units that are called packets

to identify which network layer protocol is being used
