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

Question 4

B. The last output is inverted.

Question 5

Parity systems are defined as either________ or ________ and will add an extra ________ to the digital information being transmitted.

A. positive, negative, byte
B. odd, even, bit
C. upper, lower, digit
D. on, off, decimal

Question 6

Select the statement that best describes the parity method of error detection:

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.

Question 7

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.

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.
