IRA is a 7-bit code that allows 128 characters to be defined. In the 1970s, many news papers received stories from the wire services in a 6-bit code called TTS. This code carried upper and lowercase characters as well as many special characters and for matting commands. The typical TTS character set allowed over 100 characters to be defined. How do you think this could be accomplished?

IEEE 754-2008 contains a half precision that is only 16 bits wide. The leftmost bit is still the sign bit, the exponent is 5 bits wide and has a bias of 15, and the fraction is 10 bits long. A hidden 1 is assumed as part of the significand just like the IEEE-754 format we learnt in the class. Write down the bit pattern to represent −0.15625 × 100 in IEEE 754-2008 half-precision format. You need to find out the bits for the sign, the exponent, and the fraction. To answer this question, you need to convert the decimal fraction to its binary representation. Check out the link given in Q1. You have to show all steps including the fraction conversion (from decimal to binary).

Suppose the DES Mangler function mapped every 32-bit value to zero, regardless of the value of its input, what function would DES compute? Solve this question by answering the following 3 sub-questions. What is the result of each round? What is the result after the 16 rounds? Remind DES = Initial permutation + 16 rounds + swap halves + final permutation? Assume the original message is a 64-bit message, i.e., 1 2 3 4 … 64. Specify the bit positions by then end of these 4 operation. Must provide detailed explanation of the calculation steps.

Take into consideration the binary BCH code, which is 127 bits long and has a distance of 6 bits intended for it, and use the binary field extension F 128, which is 128 bits in size. How big is the code, and can you guarantee a certain minimum distance between entries?
In the Hamming coding system (7.3), its representation is expressed as 3 control (test) bits and 7 total bits (data+control bits).In the literature, control bits are represented as (cl, c2, c3, or (pl, p2, p3, .) The bit string sent by encoding with Hamming coding (15,4) is on the receiving side, It is retrieved as 001100101100 (pl.p2.dll). According to this bit sequence;Which option is given according to the control bits (p1.p2.p3.p4) sequence of the received bit sequence?A 0110B 1100C 1001D 0011E 0010
IEEE 754-2008 contains a half precision that is only 16 bits wide. The leftmost bit is still the sign bit, the exponent is 5 bits wide and has a bias of 15, and the mantissa is 10 bits long. A hidden 1 is assumed. Write down the bit pattern to represent -1.625 * 10-2 assuming a version of this format. Calculate the sum of 2.625*102 and 4.150390625 * 10-1 by hand, assuming both numbers are stored in the 16-bit half precision described above. Assume 1 guard, 1 round bit, and 1 sticky bit, and round to the nearest even. Show all the steps.
