1. Presentation and Session 2. SNR = 30dB = 1000; Δf = 100000Hz; N = 256; Nyquist: 2 * (100000) * log 2 (256) = 200000 * 8 = 1,600,000 bytes per second Shannon: 100000 * log 2 (1001) = 100000 * 9.967226 = 996,722.6 bytes per second 3. Stop and Wait and Windows Based: Stop and Wait: Advantages: Allows user to send and receive data quicker when it there are less data needed to be sent Transmits data quickly when it is a one-on-one transmission. Disadvantages: Network time is very slow when there are large amounts of data. Only transmits data one at a time. Windows Based: Advantages: Allows the network transmission to be more flexible and transmit multiple data Disadvantages: More collisions and data lost because there is an open slot for data to be transmitted. 4. bandwidth of the medium and propagation delay 5. D = 11101010111; G = 1101; D/G => Remainder = 110; message sent is 11101010111110. 6.
