Answer 1

Redundancy:

It refers to the error detecting mechanism, in this a small group of bits or extra bits are added at the destination of every unit.

Flow control:

Flow control is defined as a set of procedures that are used to restrict the amount of the data. The sender may send before waiting for the acknowledgment.

There are different categories of flow control:

There are two mechanisms, which have been designed to control the flow of data across the communication links.
