The video tutorial discusses the network layer of the TCP model, focusing on ARP and ICMP protocols. ARP is used to resolve IP addresses to MAC addresses, facilitating communication between hosts in local subnetworks or across different networks. ICMP is primarily used to verify connectivity between hosts. The tutorial also covers how hosts communicate on network and data link layers, whether they are in the same or different networks.

Describe the communication process between two different hosts on the same network.

What challenges might arise when hosts are located in different networks?
