Which layer of ISO model establishes and terminates communication links between computers?

The Session Layer Terminates the communication links between computers actually, It maintains connection and is responsible for controlling ports and sessions.

the session layer this is the 5th layer of ISO model.

The Session layer which is the 5th layer of OSI model responsible for establishing, managing and terminating the connections between computers. 

session layer is the 5th layer in osi model which is responsible for the connection between two network nodes devices the layer establish connection between two nodes before transferring data and terminate connection after

Layer4: UDP/TCP establishes and terminates connection between computers

Data Link Layer 

establishes and terminates communication links between computers

The data link layer provides node-to-node data transfer

data link layer can communicate between terminates & computer

The data link layer provides node-to-node data transfer—a link between two directly connected nodes. It detects and possibly corrects errors that may occur in the physical layer. It defines the protocol toestablish and terminate a connection between two physically connected devices. It also defines the protocol for flow
