(a) Analyze the reason for the increase in transmission and propagation time in datagram network with useful diagram. [2 marks] (b) Justify how many bits, if any; is required as padding to transmit 75 bytes IP packet over Ethernet. [2 marks] (c) Refer to Table Q2(c). Table Q2(c) (i) Determine the transmitted bits using Cyclic Redundancy Check (CRC) method with the generator polynomial as in Table Q2(c). [4 marks ] (ii) Imagine an error occurred during transmission where the THIRD BIT from the Most Significant Bit (MSB). Prove if the receiver is able to detect this error.
