- A sender needs to send the two data items 110001 and 100110, find the checksum atsender and receiver to check if there is any error or not?A sender needs to send the four data items Ox3456, OxABCC, Ox02BC, and OxEEEE.Answer the following:a. Find the checksum at the sender site.b. Find the checksum at the receiver site if there is no error.c. Find the checksum at the receiver site if the second data item is changed to OxABCE.d. Find the checksum at the receiver site if the second data item is changed to OxABCE and the third data item is changed to Ox02BA.Suppose the sender and the receiver agree to use the bit pattern 01111110 to mark the beginning and the end of a frame. 1)The sender has the following bits to send. What does the sender actually send? 011110000111111011101111101 2) The receiver receives the following bits. What're the original data bits (note: this question has nothing to do with the previous question) 01111110111110111110001101111101000011111001111110

Explain your answer.Given the data word x^7+x^6+x^4+x^2+1and the divisor x^3+x+1, show the generation of the codeword at the sender site.
- The sender sends the following message 11011000011 to the receiver. Using Vertical Redundancy Check, which of the following will be detected as having an error and rejected using an even number of 1s?q5- How the CRC (Cyclic Redundancy Check) checksum can be applied for detecting data transmission errors? Calculate 3-bit CRC checksum for a message string 11010011101 and show the steps involved. Use 1011 as divisor and show your working.a. Suppose you have the following packet with the bits: 01111001 11001111 and 11110011 10011000. What is the Internet checksum of this packet? b. Suppose you have the following packet with the bits: 11000011 10101010, 10010001 01000101 and 11000011 10011000. What is the Internet checksum of this packet? c. For the packet in a), give an example where one bit is flipped in each of the two 16-bit words and yet the checksum doesn't change.

(1011 1011 1110 0010) and receiver has obtained following stream of bits (1011 1100 1110 1101). What bits are transmitted during this interval? Select one option: a. Undetermined, 1 b. 1,0 c. 0, undetermined d. 0,1 Clear my choiceA 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?
