Quick Summary

The "store-and-forward" scheme is a method used in packet-switched networks for data transfer. In this system, digital data is broken down into small units called packets. Each packet is temporarily stored at intermediate network nodes before being forwarded to its destination. This process allows packets to be routed independently, and if one path is unavailable, packets can be rerouted. The Internet and most local area networks (LANs) utilize this technology. While efficient, it can lead to delays and requires significant processing power.1

In a process called store-and-forward, each packet is temporarily stored at each intermediate node, then forwarded when the next link becomes available. In a connection-oriented transmission scheme, each packet takes the same route through the network, and thus all packets usually arrive at the destination in the order in…
