I only need the answers, thank you in advance.

In a communication, the transmitted data is 101010101010 and the received data is 10101001110 0. For error detection, 2D Parity algorithm is used with (3 row and 4 column). Which answer is correct? O a. Error cannot be detected O b. Error is only detected by row, but cannot be corrected O c. Error is only detected by column, but cannot be corrected O d. Error can be detected and corrected O e. Error is detected by row and column, but cannot be corrected In a full duplex communication by using UTP cable, Pt =50 w, Pc = 3 w and Adb =6,69. According to this information which answer is correct? O a. Pr = 30,36 NEXTdb = 11,69 ACRdb = 11,69 O b. Pr = 30,36 NEXTdb = 11,69 ACRdb = 11,69 O c. Pr = 47,00 NEXTdb = 16,59 ACRdb = 16,59 O d. Pr = 50,00 NEXTdb = 16,36 ACRdb = 16,36 O e. Pr = 10,71 NEXTdb = 12,22 ACRdb = 5,53 Which one is not a communication task? a. Amplifying b. Transmission system utilization c. Routing d. Addressing Oe. Security For a transmission medium, the bandwith is given as 8,46 MHz, maximum capacity is achieved by using 7 bits. According to this information which answer is correct? O a. SNRdb = 37 Max Capacity = 105,10 Mbps O b. SNRdb = 45 Max Capacity = 127,00 Mbps O C. SNRdb = 42 Max Capacity = 116,90 Mbps O d. SNRdb = 42 Max Capacity = 118,44 Mbps O e. SNRdb = 34 Max Capacity = 96,70 Mbps
