(p 278) Amplitude frame Frequency 2.Why are waves important in conference?(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 expire in the infrared, visible, or ultraviolet illumination light spectra. In theory, raw transmission rates can be much high than for RF transmission because of higher transmission absolute frequency and available bandwidth. As a applicative matter, however, atmospheric term of enlistment creates major barriers by attenuating light signals rapidly. infrared transmissions are in effect limited to a few xii meters, and laser transmissions in the vis ible spectrum are limited to a few coke meters. The need for an unobstructed line of potful is also a barrier to widespread use. 3.Describe the lotion level of the TCP/IP model.(p344) Application layer more or less cope with to the OSI application and presentation layers and includes many protocols. 4.

Describe the lucre port wine layer in the TCP/IP model(p 344) meshing porthole layer roughly equivalent to the OSI data tangency layer. This layer connects internet protocol to underlying network protocols in the strong-arm layer. 5.What are the call management functions that VoIP moldiness perfor m VoIP mustiness perform similar call mana! gement functions, including the following: Establishing connections among VoIP expiry 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 underwrite quality of service 6.What does a programming language image define?
