Flow control:

Flow control is meant only for the transmission of data from sender to receiver.
For Flow control there are two approaches : Feedback-based Flow Control and Rate-based Flow Control.
It prevents the loss of data and avoid over running of receive buffers.
Example of Flow Control techniques are : Stop&Wait Protocol and Sliding Window Protocol.

Error control:

Error control is meant for the transmission of error free data from sender to receiver.
To detect error in data, the approaches are : Checksum, Cyclic Redundancy Check and Parity Checking.
To correct error in data, the approaches are : Hamming code, Binary Convolution codes, Reed-Solomon code, Low-Density Parity Check codes.
It is used to detect and correct the error occurred in the code.
Example of Error Control techniques are : Stop&Wait ARQ and Sliding Window ARQ.
