Compute the 4-bit checksum for the hexadecimal message 5E1D0 and express your result as a hexadecimal digit.
5E1D0 = 0101 1110 0001 1101 0000 To calculate checksum: first add first 2 digits: 0101 + 1110 =10011 There is 1 as carry, it will again be added to the last 4 bits: 0011 + 1 = 0100 Now add 3rd hex digit 0001 to it 0100 + 0001 = 0101 Now add 4th hex digit 1101 to it 0101 + 1101 =10010 Add the carry again to last 4 bits: 0010 + 1 = 0011 Add 5th hex digit 0000 to it 0011 + 0000 = 0011 Now sum is 0011, So checksum is reversed of this, So it will be 1100, which is hex digit C

Add the following 16-bit hexadecimal numbers to obtain a checksum. Remember to complement your final answer and to submit your answer in hexadecimal with the 0x prefix notation. 0x2191 0x679b 0x928b 0xd0de
Suppose that a message 1001 1100 0101 1100 is transmitted using Internet Checksum (4-bit word). What is the value of the checksum?
Consider the two 16-bit words (shown in binary) below. Recall that to compute the Internet checksum of a set of 16-bit words, we compute the one's complement sum of the two words. That is, we add the two numbers together, making sure that any carry into the 17th bit of this initial sum is added back into the 1's place of the resulting sum); we then take the one's complement of the result. Compute the Internet checksum value for these...
Convert the decimal -1234 to16-bit binary and 4-digit hexadecimal
18. Computing an Internet checksum Consider the two 16-bit words (shown in binary) below. Recall that to compute the Internet checksum of a set of 16-bit words, we compute the one's complement sum [1] of the two words. That is, we add the two numbers together, making sure that any carry into the 17th bit of this initial sum is added back into the I's place of the resulting sum); we then take the one's complement of the result. Compute...
Calculate the 2's complement of the following 8-bit numbers. Express your final answers in hexadecimal. 1) 101011112 2's Complement: ___________________ 2) 111110102 2's Complement: ___________________

Hamming Code: m = 1010 (4-bit message); odd-parity scheme; Compute Hamming Code on the sender’s side. On the receiver’s side, detect and verify a 7th bit error-position in the transmitted data.
USCIUN 4 pts Compute the checksum byte (0-type) for the following array of bytes: [0x340x87,0x32) Provide your answer in decimal
consider sending a message of <Hi> that consists of 16-bit from source to destination. Your message must go through the channel coding anf line coding before transmit. (design own information interchange code) (a) consider the use if hamming codes in the channel coding to endocode the 16-bit message (i) construct the hamming codeword for this message. (ii) bt inverting one message bit in Hamming codeword(to represent a 1bit-error) and demonstrate how the recipient can use thr check bits to correct...
