There is one best switching technique.

• A. True
• B. False
• C. Sometimes
• D. Not enough information

Answer: (B)

There isn’t a single technique that’s best in every situation. Switching methods trade off latency, error detection, and throughput, so what’s optimal depends on the network’s needs. For example, store-and-forward checks the entire frame for errors before forwarding, which helps ensure correct delivery but adds delay due to buffering. Cut-through forwards as soon as the destination address is read, reducing latency but potentially passing along frames with errors. Fragment-free sits between these, aiming for a middle ground by checking a portion of the frame before forwarding. In practice, networks choose the method based on what matters most there—speed or reliability or a balance of both—so the idea that one technique is universally the best isn’t accurate.
