1. Memory Error Detection and Correction (a) Explain the idea of even/odd parity bit strings. (b) Create the 2D parity check matrix (Row, Column, Matrix parity bits) for the following data: 1010, 1111, 1001, 0100. (c) Using Hamming(15,11), check the Hamming codeword for correctness: 101101001010100. State whether or not the codeword is correct. If the codeword is not correct, determine the mistake (flipped bit) and generate the correct codeword.

B={1,2,3,4,5,6,7,8,9,10} Using the n-bit binaries to which subset in the power set of the ordered set B does the following bit string represent: 1100000011

Convert each of the following base ten resprentations to its equivalent two's complement form using pattern of 8 bits. 1. 6[, 2. -6

In single precision (IEEE-754 standard), 8 bits are used for storing the exponent (the bias is 127), and 23 bits are used for storing the mantissa.  (a) What are the smallest and the largest positive numbers that can be stored in single precision? (b) What is the smallest value of the mantissa that can be stored?

1 a. If the last operation performed on a computer with an 8-bit word was an addition in which the two operands were 00000010 and 00000011, what would be the value of the following flags? ● Carry • Zero • Overflow Sign • Even Parity ● Half-Carry b. Repeat for the addition of -1 (twos complement) and +1.

[10] Write the 8-bit representation of –6810.

Question 3  Generate the parity bits (row parity) and longitudinal parity (column parity) bits for even parity for the characters 1101001, 1011010, 0011110, 0110110, and 1110110. Show your calculation      Full explain this question and text typing work only thanks

Extend the ASCII code to 8 bits by adding a 0 to the left of each character and find the bit combinations needed to store the character strings given below. Give your answers in hexadecimal notation.
