Error Detection and Correction Flashcards
1
Q
what is an Even parity?
A
its checking can only detect an odd number of bits being corrupted
2
Q
what are check sums?
A
are associated with packets of data and are integral part of the packet
they counting the numbers of 1BITs in a packet and sending this as a mathmatical total at the end of the packet
3
Q
what is checking itself?
A
involves process where data packets are checking at the destination looking for errors, if errors are found the data will be transmitted again
4
Q
what is CRC?
A
Cyclic Redundancy Check
its an error detection mechanism in which a special number is appended to block of data in order to detect any changes introduced during storage. its able to detect more than just one error within a packet
