(a) simple parity check (b) two-dimensional parity check
(c) crc (d) checksum
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
Detection of errors and retransmission of frames that are received in error.
1)transcription errors. 2)computation errors. 3)algorithm errors.

hii frnds it provides framing error control, flow control and link management, error detection and correction
Parity
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.
Simple parity check is easy to implement and helps to detect single-bit errors in data transmission. It is a simple and fast error detection technique that adds minimal overhead to the data being transmitted. However, it is limited in its ability to detect multiple bit errors or correct any errors detected.
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
The primary benefit of CRC is that it can detect more types of data errors than the other two methods.
A special system of multiple parity bits (e.g. Hamming parity) that allows not only error detection but limited error correction.Ordinary single bit parity can detect reliably single bit errors.Hamming parity can correct single bit errors and detect reliably double bit errors.
c) Check frame sequence. The FCS (4 bytes in length) field is used to detect errors in a frame
Error handling refers to the anticipation, detection, and resolution of programming, application, and communications errors.
Detection of errors and retransmission of frames that are received in error.
The central concept in detecting or correcting errors is redundancy. 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.
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
