What feature is NOT typically associated with packet-switching systems?

  1. Data sent in fixed sizes.

  2. Dynamic routing of data packets.

  3. Ability to handle multiple data streams simultaneously.

  4. Each packet can follow a different route.

The correct answer is: Data sent in fixed sizes.

In packet-switching systems, data is divided into smaller packets for transmission, allowing for efficient use of network resources. One key characteristic of these systems is that packets can vary in size rather than being sent in fixed sizes. This variability helps to optimize the use of bandwidth and adapt to differing data transmission needs. The dynamic routing of packets allows them to navigate through the network independently based on current network conditions, thus improving resilience and load balancing. Packet-switching systems also excel in managing multiple data streams simultaneously, as they can interleave packets from various sources, maximizing throughput. Additionally, since each packet can travel by different routes to reach the same destination, this feature contributes to the robustness of the system, allowing it to adapt to network changes and potential congestion. In contrast, the aspect of data being sent in fixed sizes is generally associated with circuit-switching systems, where a dedicated path is established for the entire duration of the communication session, thus necessitating uniform packet sizes for efficient transmission. This is why the concept of sending data in fixed sizes is not typical of packet-switching systems.
