4.

Select one of the following statements that best describes the parity method of error detection:

 [A]. Parity checking is best suited for detecting single-bit errors in transmitted codes. [B]. Parity checking is best suited for detecting double-bit errors that occur during the transmission of codes from one location to another. [C]. Parity checking is not suitable for detecting single-bit errors in transmitted codes. [D]. Parity checking is capable of detecting and correcting errors in transmitted codes.

 \$Unil said: (Oct 15, 2012) Parity is a bit checker so if Even no.of error occur it won't ditinguish. EX: Data to b transmitted= 1010101 Even parity of 1010101 is '0' (if odd parity '1') Let the data transmitted as 1. 1000101 - single bit error; parity is '1' 2. 1001101 - two bits error; parity is '0' Therefore in 1 (ie single bit error) parity is missmatch [Parity is calculated by just adding no.of ones; if we follow even parity then over count shd be 0, if not we shd set ie make parity as 1]
