How Network Packets Work

1. Segmentation: Large files are broken into smaller packets for efficient transmission.

2. Header Addition: Each packet gets a header with sequence number, destination address, and error checking data.

3. Routing: Packets can take different routes through the network to reach their destination.

4. Reassembly: The destination computer collects all packets and reassembles them in the correct order.

5. Error Detection: If packets are lost or corrupted, they can be retransmitted.
