Data Link Layer deals with framing the bit stream and there may occur errors while transmission of data from sender to reciever. 
So, this course is going to tell about types of errors, detection and correction techniques of errors.
After Error Control, we will be discussing about Flow Control so that speed of sending and recieving is maintained.
