Q1. How does a single-bit error differ from a burst error? In a block code, a dataword is 20 bits and the corresponding codeword is 25 bits. What are the values of k, r, and n according to the definitions in the text? How many redundant bits are added to each dataword? Q2. In CRC, if the dataword is 5 bits and the codeword is 8 bits, how many Os need to be added to the dataword to make the dividend? What is the size of the remainder? What is the size of the divisor? Q3. Given the dataword 10100110101 and the divisor 10101, show the generation of the CRC codeword at the sender site (using binary division). Now convert the dataword and divisor in polynomials and show the generation of the CRC codeword at the sender site. Q4. A sender has four data items to send: 466F, 726F, 757A, and 616E. What is the value of the Checksum? Q5. a) What is the function of the twisting in the twisted-pair cable? b) What is the purpose of cladding in an optical fiber?

Define the function lake_to_tli3_dict(readings) that takes a list of (lake_name, chla, tn, tp) tuples and returns a dict mapping lake names to trophic level index values. That is, the keys are lake names and the values will be TLI3 values. Notes: You will need to have import math as your first line of code. You must include and use/call the trophic_level_index function that you wrote in Question 1. trophic_level_index must still work as specified in Question 1. Lakes should be added to the dictionary in the same order as they appear in the readings list. If a lake appears in the readings list more than once, then the TLI for the last occurrence in the readings list should be the one that appears in the result. (This should happen naturally, since the lake name can only occur in the dictionary once.) For example: Test Result names_cnp_1 = [('Lake Brunner', 0.8, 218.0, 6.0), ('Lake Carrot', 5.1, 505.0, 18.5) ] tli3_dict = lake_to_tli3_dict(names_cnp_1 ) print(tli3_dict)…
