- The even parity bit that must be added to the 6-bit message (101001) is:arrow_forwardWhat decimal number does the bit pattern 1011 1111 1100 0000 0000 0000 0000 0000 represent if it is a floating point number in IEEE 754 standard (single precision)?arrow_forwardLPC2148 observes the Big Endian layout, which means: Least Significant Bit equals how many bits? Most Significant Bit equals how many bits?arrow_forward
- Find the Bitwise AND of the following bit strings: 01 1011 010111 0011 1101 Question 11 options: Find the Bitwise OR of the following bit strings: (same strings as previous question) 01 1011 010111 0011 1101 Question 12 options: Find the Bitwise XOR of the following bit strings: (same strings as previous question) 01 1011 010111 0011 1101 Question 13 options:arrow_forwardConvert the following number from base 10 to hexadecimal (base 16): 1037 Fill in the blanks to get the correct result. 1037 Blank # 2 Blank # 4 modulo modulo modulo 16 = 16 16 = = Blank # 1 Blank # 3 Blank # 5 Express your answer as a 16-bit hexadecimal number: Blank # 6arrow_forwardConvert the following numbers into a signed 8-bit number: -42 -111 ↑ ↑ signed 8-bit number signed 8-bit numberarrow_forward
- How many bit strings contain exactly five 0’s and ten 1’s if every 0 must be immediately followed by a 1?arrow_forwardOne way of detecting errors is to transmit data as a block of n rows of k bits per row and adding parity bits to each row and each column. The lower-right corner is a parity bit that checks its row and its column, Will this scheme detect all single errors? Double errors? Triple errors?arrow_forwardWhen the result of an unsigned arithmetic operation is too big to fit into the destination, what flag is set?arrow_forward
- To convert the decimal number 30 to an 8-bit binary number, use the following representation methods: a) the inverse of its complement: b) Excess-M:?arrow_forwardone way of detecting errors is to transmit data as a block of n rows of k bits per row and adding parity bits to each row and each column. the lower-right corner is a parity bit that checks its row and its column, will this scheme detect all single errors? double errors? triple errors?arrow_forwardWhen a bit is "activated," what does it mean in terms of a number? What does an unconnected bit's numerical representation indicate?arrow_forward
