There are several types of Multiplexing. What distinguishes Frequency Division Multiplexing What Division Multiplexing What distinguishes Wave Division Multiplexing If you were buying a multiplexer, why would you choose either a FDM or TDM? Layer Two: controls access and handles errors. Describe three access control methodologies. Describe the techniques in Layer 2 that Prevent errors. Describe the methods in Layer 2 that Control errors. Describe three Layer 2 Error Detection methods Draw how a series of FOUR separate messages would be successfully sent from one computer to another using ARQ if: the first message was transmitted without error the second message was initially transmitted with an error the third message was initially lost and the ACK for the fourth message was initially lost. You have downloaded a number of Word and PowerPoint files from D2L. Assuming that the next file you will download is 3.4Mb, how long would it take using the following circuits? Also assume that control characters and management overhead adds a total of an extra 10% to the message. Dial up modem at 33.6 Kbps Cable modem at 384 Kbps T-1 line at 1.5 Mbps Create a table for the OSI protocol stack listing: Layer Number Layer Name Layer Functions in detail Layer Sample Protocol(s) Layer Name for its "chunk of data" if applicable
