Question 11 Not yet answered P Flag question A computer system uses 8 bits to represent floating-point values. The 8 bits are organised as follows: The first bit is a sign bit (0 for positive, 1 for negative). The middle 3 bits are the exponent, which uses bias of 3. The last 4 bits are the significand, which is normalised in the same way as the significand is normalised in IEEE-754 formats. The format does not reserve any special values. The following arithmetic operation is performed on this system: 00011000 x 11000110 The result is then stored in the same 8-bit floating-point format. What is the relative error of the stored result comapred to the value of the result of the arithmetic operation? Answer s are rounded to 5 decimal places. O a. None of the other answers. O b. 0.03030% O c. 0.03125% O d. 0.97865% O e. 0%

Suppose the following algorithm is used to encrypt a password   A three-digit decimal number is input as the password Your Student ID last two-digit are added to this password Then it is converted to a binary number Then it is converted to 1's complement representation And lastly, it is converted to a Hexadecimal number Finally, this number is printed on the screen.   What will be output if you input “786” in step 1 as a three-digit decimal number in the above algorithm?   My student id is : 12903

The output of an AND gate with three inputs, A, B, and C, is HIGH when O A = 1, B = 1, C = 0 O A = 0, B = 0, C = 0 O A = 1, B = 1, C = 1 O A = 1, B = 0, C = 1

A computer byte consists of eight bits, each bit being either a 0 or a 1. Assume that characters are represented using a code that uses a byte for each character. Some written languages, such as Chinese and Japanese, use tens of thousands of different characters. If a language uses roughly 78,000 characters, a computer code for this language would have to use how many bytes per character? x bytes Need Help?

Solve only part c

value_a = 179 value_b = 215 sum = value a + value b = (enter answer in decimal) value_c = 137 value d = 183 sum = value_c + value_d =| (enter answer in decimal) In this exercise, the following two16-bit positive integers are to be added: value_a = 46861 value_b = 51071 If only 16 bits are available to represent the answer, then the result will be, sum = value_a + value_b (enter answer in decimal) You have designed a number system which uses 19-bit positive integers In your system what is the result of, value a = 393710 value_b = 394509 sum = value_a + value_b (enter answer in decimal)

True/False In Floating Point Addition, the exponents of the two numbers being added need to be made equal before the mantissa fields can be added, as this ensures that the bit positional values are now aligned

Computer Science Write a regular expression that matches a normalized 32-bit binary IEEE 754 FP number and has no leading or trailing zeros. As a reminder, the leading 1 before the decimal point is implicit, so your regular expression should allow up to 32 bits after the decimal point. Valid: 0.0, 1.0, 0.1, 1.001100101 Invalid: 00.0, 01.01, 10.11110, 1.0000000000000010
