UDP and TCP use 1s complement for their checksum. Suppose you have the following two 8-bit bytes: 0101, 1010. What is the 1s complement of the sum of these 8-bit bytes? Suppose the two bytes are altered during transmission with the checksum as follows: 1001, 0110. Can the checksum be used to detect the alteration?

1. a)UDP and TCP use 1’s complement for their checksums. Suppose you have the following three 8 bit bytes: 0101 0011, 0111 0110, 1001 0011. What is the 1’s complement of the sum of these 3 8-bit bytes? Show all work. Why is it that the 1’s complement is used and not just the sum? What is the sum of the three 8 bit bytes and the checksum you just computed? What is it if you change the first 8...

4. UDP and TCP use 1's complement for their checksums. Suppose you have the following two 16-bit words: 0101 0101 0101 0101 and 1010 1010 1010 1011. 4.a. (2 pts.) What is the 1's complement of the sum of these words? Show all work. 4.b. (2 pts.) With the 1's complement scheme, how does the receiver detect errors? 4.c. (2 pts.) Is it possible that a 4-bit error will go undetected? If so, provide an example. 4.d. (2 pts.) Is...

WHAT IS THE ANWER FOR THE TWO
QUESTIONS
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...

In the last module you learned a formula for calculating bit rate, R = b/t, that is the number of bits divided by the time. This formula expresses the number of bits that are transmitted over a circuit in a given period of time. In practice, however, we are not only concerned with the number bits transmitted, but also with the number of data bits transmitted over a circuit. The data bits are those that the sender decides to send...
