Used for error detection
In error detection we detect the error.but in error correction we can detect as well as coreect the error both.in error detection we use parity multiplication system i.e even and odd parity.and in error correction we use hamming code as a example.
1)Time taken to error correcting is less than doing detection and retransmission. Bandwidth use will be less. 2) In detection and retransmission if back messaging occurs the bandwidth will be more
Control systems are synchros which are used in error detection. They provide a voltage to be converted to torque through an amplifying method.
Error handling refers to the anticipation, detection, and resolution of programming, application, and communications errors.
1)Time taken to error correcting is less than doing detection and retransmission. Bandwidth use will be less. 2) In detection and retransmission if back messaging occurs the bandwidth will be more
Detection of errors and retransmission of frames that are received in error.
Parity
CRC is used for this purpose. The control field is HEC (header error control).
To be able to detect or correct errors, we need to send some extra bits with our data. These redundant bits are added by the sender and removed by the receiver. Their presence allows the receiver to detect or correct corrupted bits
Systematic error is the difference between the actual value of what is being measured and the value you found. The results of systematic error are precise but not accurate.
