How does parity checking detect errors? You can determine if an error occurred during transmission by calculating the parity of the received bytes and com- paring the generated parity with the transmitted parity. Parity can only detect an odd number of errors. If an even number of errors occurs, the computed parity will match the transmitted parity.
How does parity check for errors in memory? Parity checking puts a byte into memory along with its parity bit and then reads the byte from memory. If the byte plus the parity bit matches what was sent, the memory is okay. Otherwise, we have a parity error. Parity can be set to odd, even, or off.
How errors are detected using parity checking what are the limitations of parity checking? There are only two disadvantages to using parity bits: It’s N extra bits-per-word that have to be transmitted. Parity checking can’t detect all forms of errors.
What type of errors can be detected by parity check code? The parity code is used for the purpose of detecting errors during the transmission of binary information. The parity code is a bit that is included with the binary data to be transmitted. The inclusion of a parity bit will make the number of 1’s either odd or even.

What might be some of the limitations of an intrusion detection system such as Snort?
An IDS cannot see into encrypted packets, so intruders can use them to slip into the network. An IDS will not register these intrusions until they are deeper into the network, which leaves your systems vulnerable until the intrusion is discovered.
Why is it hard to find planets around other stars?
Finding planets orbiting distant starts is difficult because planets are much dimmer than the stars they orbit, and both the stars and planets are so far away. It is a bit like trying to see a mosquito at night, flying next to a car’s headlight, from 100 miles away!
