Error Detection-- CRC

• Powerful error detection system
• Rather than addition, binary division is utilized
• A series of redundant bits called "CRC" or else "CRC remainder" is appended to the data unit consequently that the resulting data unit becomes divisible by a predetermined binary number
• At the receiver side the incoming data unit is divided by the similar predetermined number.
• If there is no remainder entirely the data unit is accepted
• If there is a remainder entirely the receiver indicates that the data unit has been damaged during transmission
