Explanation/Reference:
Explanation:
When two computers are going to communicate through a connection-oriented Protocol, such as TCP/IP, they will first agree on how much information each computer will send at a time, how to verify the integrity of the data once received, and how to determine whether a packet was lost along the way. The two computers agree on these parameters through a handshaking process at the transport layer, layer 4.
Incorrect Answers:
B: Connection-oriented protocols are located at transport layer, not at the Application layer.
C: Connection-oriented protocols are located at transport layer, not at the Physical layer.
D: Connection-oriented protocols are located at transport layer, not at the Network layer.
