Packet Splitting: Large messages are broken into numbered packets. Each packet travels independently through the network and may take different routes.
Routing: Routers forward each packet toward the destination based on IP addresses. If one path is congested, packets can take alternate routes.
Reassembly: The destination computer collects all packets and reassembles them in the correct order using sequence numbers, even if they arrive out of order.
Fault Tolerance: If a router fails, packets automatically find alternative paths. This redundancy is the core design principle of the Internet.

How the Internet Works: Your message "HELLO" is split into 5 packets (H-E-L-L-O). Each packet gets a header with source IP, destination IP, and sequence number. Packets route independently through the mesh network. TCP guarantees reliable delivery and correct reassembly.
