- Parity bits can identify how many message mistakes at once?The following bits have been received: 11011110110. The sender is using CRC with the generator 1100. Does the received data contain an error? You must show your work to receive marks (an answer of just ‘yes’ or ‘no’ will receive no marks).The data to be transmitted is 10111110 11000101; the data received is 10110010 11010101. (1) Compute for the checksum at the sender side; (2) Confirm whether the checker successfully detects the errors by inverting the sum of the checksum and the sum at the receiver side.
- In a two-dimensional decimal parity-check which uses check digits, if we receive the following transmission: 257103550 Assuming there is at most 1 error, which of the following is the correct original underlying message: a) 257303550 b) 217503550 c) 2150 d) 7355 e) 2530With the use of a Checksum Method, show the transmission of “m” and “n” from the sender to destination side. The following block is sent: 00001111 11110000 11001100 10101010. With the use of a two-dimensional parity check and assuming that no single/multiple-bit or burst error have occurred, what will be received in the receiver side? NOTE: Put a space after each frame.Assuming that the sender and receiver’s agreed upon code is 1101 and the information word is 11001101, the resulting CRC code word that is to be transmitted is _____.
- A sender transmits a message: 11001010; the data received by the receiver is 11010000. Using vertical redundancy check with even parity, (1) does the receiver interpret the message with error or with no error? (2) Is the error checker correct or incorrect?a) Compute the CRC for the following message M = 1110 1010 1110 0100 0101 using the generator x4+x2+x+1. Show your detailed work. Let us call M’ the message M after appending the CRC to it. b) Suppose the following error message E = 1111 0000 1110 0000 1010 0000 is XORed to M’ obtained in part a. Is the error detected at the receiver? Show your detailed work.Q1. (a) Find CRC code for message bits to be transmitted which is 11001110 with generator value 1011 known to receiver.

Suppose that the 4-bit generator (G) is 0101, and r = 3A bit stream 10011101 is transmitted using CRC method. The generator polynomial is x^3 + 1. Show the actual bit string transmitted.
