The TCP/IP suite of protocols includes Address Resolution Protocol (ARP), Internet Protocol (IP), Internet Control Message (ICMP), Internet Group Management Protocol (IGMP), Transmission Control Protocol (TCP), and User Datagram Protocol (UDP).

The TCP/IP suite operates at Layer 2, Layer 3, and Layer 4 of the OSI model follows:

Layer 2, Data Link: ARP
Layer 3, Network: IP, ICMP, IGMP, ARP
Layer 4, Transport: TCP, UDP
The TCP/IP suite operates at layer 2, and layer 3 of the TCP/IP model as follows:
Layer 1, Link: ARP
Layer 2, Internet: IP, ICMP, IGMP, ARP
Layer 3, Transport: TCP, UDP

Objective: Network Concepts
Sub-Objective: Describe the operation of the following: IP, TCP, UDP, ICMP
