*NEEDS TO BE IN CRC CHECKSUM NOT IN PROGRAMMING LANGUAGE FORM.*

2. (6 pts.) (CRC checksums) (a) Use the reference "CRC16-CCITT.pdf' as a guide (and reference, if needed CRC16-CCITT checksum for the text string of three lowercase letters "ucf" (or, (b) Verify your CRC16 checksum result of Part (a) using the checksum value calculated (c) Use HxD to calculate the CRC16 checksum of the string "ucg" (whose ASCII code is http://en.wikipedia.org/wiki/Crc16) and show your work to manually calculate the equivalently, calculate the CRC16 checksum of the file "CRC-test" of size three bytes) by the hex editor HxD (available at https://mh-nexus.de/en). different from the ASCII code of "ucf" by one single bit). How many bits are different between the two CRC16 checksums of (b) and (c)? (d) Estimate how many 3-byte strings (i.e., considering all 16,777,216 strings in the range 16 checksum as that of the string of 0x000000 to OxFFFFFF) will have the same CRC "ucf". Explain how you determine your answer. (Extra Credit, up to 2 pts.) Identify a three-character text string consisting of letters only (lower and/or upper-case) which has the same CRC16 checksum as that of "ucf" Explain how you determine your answer. 2. (6 pts.)
