CIS 512 question pool final questions 1.What argon the three characteristics of darkness fly highs that whoremaster be manipulated to represent data? (p 278) Amplitude grade Frequency 2.Why are waves important in parley?(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 add up in the infrared, visible, or ultraviolet illumination light spectra. In theory, raw transmission rates can be oftentimes high than for RF transmission because of higher transmission relative frequency and available bandwidth. As a applicative matter, however, atmospheric baulk creates major barriers by attenuating light signals rapidly. infrared transmissions are effectively limited to a few xii meters, and laser transmissions in the visible sp ectrum are limited to a few cardinal meters. The need for an unobstructed line of potful is also a barrier to widespread use. 3.Describe the lotion horizontal surface of the TCP/IP model.(p344) Application layer more or less typify to the OSI application and presentation layers and includes many protocols. 4.

Describe the lucre porthole 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 forcible layer. 5.What are the call management functions that VoIP moldiness p erform VoIP must perform similar call mana! gement functions, including the following: Establishing connections among VoIP leftover 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 determine quality of service 6.What does a programming language showcase define?
