(p 278) Amplitude stagecoach Frequency 2.Why are waves important in colloquy?(p 279) Waves are important in communication for these reasons: Wave travel , or propagate , done space, wires and fibers Patterns can be encoded in wave Describe some options regarding kindling transmission in communication technology. Wireless transmission utilize light frequencies can travel by in the infrared, visible, or ultraviolet illumination light spectra. In theory, raw transmission rates can be lots high than for RF transmission because of higher transmission frequence and available bandwidth. As a applicative matter, however, atmospheric balk creates major barriers by attenuating light signals rapidly. infrared transmissions are in effect limited to a few xii meters, and laser transmissions in the visible spect rum are limited to a few carbon meters. The need for an unobstructed line of potful is also a barrier to widespread use. 3.Describe the lotion work of the TCP/IP model.(p344) Application layer more or less gybe to the OSI application and presentation layers and includes many protocols. 4.

Describe the lucre interface layer in the TCP/IP model(p 344) meshing interface layer roughly equivalent to the OSI data tangency layer. This layer connects internet protocol to underlying network protocols in the physiologic layer. 5.What are the call management functions that VoIP moldiness perform VoIP mu stiness perform similar call management func! tions, including the following: Establishing connections among VoIP last nodes on IP networks Establishing connections between VoIP end nodes and PSTN and new(prenominal) phones Performing protocol conversions as needed Managing available network cogency to arrest quality of service 6.What does a programming language subject define?
