When parity detects an error what happens?

A parity error always causes the system to hault. On the screen, you see the error message parity error 1 (parity error on the motherboard) or parity error 2 (parity error on an expansion card)

Which statements best describes redundancy checking?

Redundancy checking is a technique used to detect errors or errors in a data transmission. It involves adding extra bits to the data to create a checksum or parity. The receiver then checks for errors by recalculating the checksum or parity and comparing it to the received value. If they do not match, an error is detected.

Explain the type of error which will be detected when using parity error checking on a serial link?

if the stop bits does not appear when it is supposed to, the UART considers the entire word to be garbled and will report a framing error regardless of the whether the data was received correctly or not, the UART automatically discards the start,parity and stop bits.

What does the method known as parity do?

In RAM, parity is a type of built-in error-checking system. After the 8 bits in a byte receive data, even parity works by adding to total number of 1s. If the number is odd, the parity bit is set to 1; if the number is even, the parity bit is set to 0. When the data is read back, the total is added up again and compared to the first total. If the parity bit is 1, the data is error-free, but if the total is odd and the parity is 0, the chip recognizes a problem and gets rid of the data. Odd parity works in the same fashion, just the other way around.
