Error control:
Error control is the technique of detecting and correcting blocks of data during communication. In other words, it checks the reliability of characters both at the bit level and packet level. If proper error control is in place, transmitted and received data is ensured to be identical, as in many cases communication channels can be highly unreliable.
Flow control:
Flow control is the mechanism that ensures the rate at which a sender is transmitting is in proportion with the receiver’s receiving capabilities.
Flow control is utilized in data communications to manage the flow of data/packets among two different nodes, especially in cases where the sending device can send data much faster than the receiver can digest.
Access control : Access control is a way of limiting access to a system or to physical or virtual resources. In computing, access control is a process by which users are granted access and certain privileges to systems, resources or information.
In access control systems, users must present credentials before they can be granted access. In physical systems, these credentials may come in many forms, but credentials that can't be transferred provide the most security.

The main difference between the flow control and error control is that the flow control observes the proper flow of the data from sender to receiver, on the other hand, the error control observes that the data delivered to the receiver is error free and reliable..
