State the significance of twisting in the RJ45 cable. Give an example. Describe the component Q of optical fiber cable. Core Q Insulation Explain how does sky propagation differs from line-of-sight propagation? Two communicating devices are using a single bit even parity check for error detection. The transmitter sends the byte 10101010 and, because of channel noise, the receiver gets the byte 10011010. Will the receiver detect the error? Why and why not? For P101001 and M = 11100011. Find the CRC
