QUESTION 6 What is the largest unsigned number that can be expressed with 5 bits? What is the smallest unsigned number that can be expressed with 5 bits? QUESTION 7 The following is a string of ASCII characters whose bit patterns have been converted into hexadecimal for compactness: 4A EF 68 68 20 C4 EF EF. Or the 8 bits in each pair of digits, the left most is a parity bit. The remaining bits are the ASCII code. a) Convert to bit form and then decode the ASC (the decoded characters here) b). Determine the parity used: odd or even: QUESTION 8 What is the largest signed number that can be expressed with 7 bits? What is the smallest signed number that can be expressed with 7 bits? (If your answer is a positive value, do not type the sign of +)
