1. Show from the truth table how an exclusive-OR gate can be used to invert the data on one input if the other input is a special control function.
Options
A. Using A as the control, when A = 0, X is the same as B. When A = 1, X is the same as B.
B. Using A as the control, when A = 0, X is the same as B. When A = 1, X is the inverse of B.
C. Using A as the control, when A = 0, X is the inverse of B. When A = 1, X is the same as B.
D. Using A as the control, when A = 0, X is the inverse of B. When A = 1, X is the inverse of B.

3. Parity systems are defined as either________ or ________ and will add an extra ________ to the digital information being transmitted.
Options
A. positive, negative, byte
B. odd, even, bit
C. upper, lower, digit
D. on, off, decimal

5. Determine odd parity for each of the following data words:
1011101 11110111 1001101
Options
A. P = 1, P = 1, P = 0
B. P = 0, P = 0, P = 0
C. P = 1, P = 1, P = 1
D. P = 0, P = 0, P = 1

6. Select the statement that best describes the parity method of error detection:
Options
A. Parity checking is best suited for detecting double-bit errors that occur during the transmission of codes from one location to another.
B. Parity checking is not suitable for detecting single-bit errors in transmitted codes.
C. Parity checking is best suited for detecting single-bit errors in transmitted codes.
D. Parity checking is capable of detecting and correcting errors in transmitted codes.
