    What is the decimal equivalent for binary number 11001?

    • 24

    • 25

    • 26

    • 28

    Correct Answer
    A. 25
    Explanation
    The binary number 11001 can be converted to decimal by multiplying each digit by the corresponding power of 2 and adding them together. In this case, the calculation would be: (1 * 2^4) + (1 * 2^3) + (0 * 2^2) + (0 * 2^1) + (1 * 2^0) = 16 + 8 + 0 + 0 + 1 = 25. Therefore, the decimal equivalent for the binary number 11001 is 25.

    What is the hexadecimal representation for the binary number 100100101011 ?

    • 0xABC

    • 0x911

    • 0x92B

    • 0x92C

    • 0x94C

    Correct Answer
    A. 0x92B
    Explanation
    The hexadecimal representation of a binary number is obtained by grouping the binary digits into sets of four and converting each set into its corresponding hexadecimal digit. In this case, the binary number 100100101011 can be grouped as 1001 0010 1011. Converting each group into hexadecimal, we get 9 2 B. Therefore, the hexadecimal representation for the given binary number is 0x92B.

    What is the base 10 number, 312, expressed as hexadecimal ?

    • 0xCC2

    • 0x3B2

    • 0x444

    • 0x138

    • 0xEF2

    Correct Answer
    A. 0x138
    Explanation
    The base 10 number 312 can be converted to hexadecimal by dividing it by 16 repeatedly and noting down the remainders. Starting from the rightmost digit, the remainders are 12, 3, and 1. These remainders correspond to the hexadecimal digits C, 3, and 1 respectively. Therefore, the hexadecimal representation of 312 is 0x138.

    Attach an EVEN parity to codeword 011 1000

    • 1

    • 0

    • 10

    • 11

    Correct Answer
    A. 1
    Explanation
    The given codeword is 011 1000. To attach an EVEN parity, we need to count the number of 1s in the codeword. If the count is even, we append a 0 to the codeword. If the count is odd, we append a 1. In this case, there are 3 1s in the codeword, which is an odd count. Therefore, we append a 1 to the codeword to achieve an EVEN parity.

    What is the base 10 number 233, expressed as binary ?

    • 11101001

    • 11111001

    • 11101011

    • 11011011

    • None of the above

    Correct Answer
    A. 11101001
    Explanation
    The base 10 number 233 can be expressed as binary by repeatedly dividing it by 2 and noting the remainder. Starting with 233, the remainder is 1. Dividing 233 by 2 gives 116 with a remainder of 0. Dividing 116 by 2 gives 58 with a remainder of 0. Dividing 58 by 2 gives 29 with a remainder of 0. Dividing 29 by 2 gives 14 with a remainder of 1. Dividing 14 by 2 gives 7 with a remainder of 0. Dividing 7 by 2 gives 3 with a remainder of 1. Dividing 3 by 2 gives 1 with a remainder of 1. Finally, dividing 1 by 2 gives 0 with a remainder of 1. Reading the remainders from bottom to top gives the binary representation of 233 as 11101001.

    What is the decimal equivalent for BCD number 136?

    • 1000 0011 0110

    • 0001 0011 0110

    • 0010 0010 0101

    • 1100 0001 0101

    Correct Answer
    A. 0001 0011 0110
    Explanation
    BCD (Binary-Coded Decimal) is a system for representing decimal numbers using binary code. Each decimal digit is represented by a four-bit binary code. To convert the BCD number 136 to decimal, we need to break it down into its individual digits and their corresponding binary codes:
    1 = 0001
    3 = 0011
    6 = 0110
    Therefore, the BCD representation of 136 is 0001 0011 0110.
