Error Detection Flashcards
1
Q
What is a parity bit?
A
A bit which can detect corruption in data by observing whether the amount of 1’s is even or odd.
2
Q
What is Check Sum Error Detection?
A
CS involves adding each bit together an then dividing it by 256 and observing the remainder. This is then stored and checked after transmission.
3
Q
What is Cyclic Redundancy Checking?
A
All bits are treated as a single binary number. The mod of this is then stored (16 or 32 bit).
4
Q
What is the most effective form of error detection?
A
Cyclic Redundancy Checking (CRC)
5
Q
What is the lease effective form of error detection?
A
Parity Bits
