Flow Control
The problem that occurs in data flow is that the slower receiver cannot cope with the faster sender which causes overflow and loss of data. There are two approaches of flow control. In Feedback-based flow control approach, receiver sends feedback to the sender telling how it is doing. In Rate-based flow control, pre-communication occurs between sender and receiver and the data transfer occurs at the rate which the receiver can receive without overflow.

Flow Control
Flow Control deals with the issue where the sender sends data at the higher rate than the receiver can receive. Flow control can be done by using the buffer on the receiver side. But, the main problem that occurs, in this case, is that the slower receiver cannot cope with the faster sender which causes overflow and loss of data.
There are two approaches to flow control:
Feedback-based flow control: Receiver sends feedback to the sender telling how it is doing.
Rate-based flow control: In this approach, pre-communication occurs between sender and receiver and the data transfer occurs at the rate which the receiver can receive without overflow.
