Which of the following involves slicing digital messages into parcels, transmitting them along different communication paths, and reassembling them at their destinations?

Question

BlackTom AI · Accepted Answer

Packet switching divides a digital message into smaller units called packets, sends those packets independently across the network (potentially via different paths), and reassembles them at the destination.

1. Relevant knowledge points and concepts
- Packet switching: segmentation of data into packets, each with header information (source, destination, sequence number), store-and-forward transmission by routers, and reassembly at destination.
- Circuit switching: a dedicated path for the entire communication (contrast).
- Multiplexing: combining multiple signals onto a single channel (time-division, frequency-division), not necessarily fragmenting and reassembling messages across different routes.
- ATM (Asynchronous Transfer Mode): transfers fixed-size cells (53 bytes) using cell switching and often virtual circuits; related but distinct from general packet switching.
- Routing vs switching: routing selects paths for packets; switching is the broader forwarding/handling mechanism.

2. Step-by-step reasoning
- The phrase “slicing digital messages into parcels” refers to breaking a message into packets — a defining feature of packet switching.
- “Transmitting them along different communication paths” describes the independent forwarding of packets based on current network routing decisions; packets can take different routes to the same destination.
- “Reassembling them at their destinations” refers to using sequence numbers and buffers to rebuild the original message from received packets — another hallmark of packet-switched networks.

3. Intermediate steps / evidence
- Example: An email or file is broken into packets; router A might forward packet 1 via path X, router B forwards packet 2 via path Y; destination uses sequence numbers to reorder and reassemble.

4. Why the correct answer is correct
- Packet switching explicitly includes segmentation, independent path forwarding, and reassembly. That matches the question wording exactly.

5. Why other options are incorrect
- Packet shifting: not a standard term in networking; meaningless here.
- Multiplexing: combines multiple streams onto one medium; doesn’t imply slicing a single message and using different routes.
- Packet routing: is the process of choosing routes for packets but doesn’t name the end-to-end practice of slicing and reassembling.
- ATM: uses fixed-size cells and virtual circuits; related technology but not the generic concept described.

6. Conclusion
The correct answer is Packet switching, which matches the provided answer.
