Management Information System (MIS) Practice Exam

Which statement is true about packet-switching systems?

1. Each packet must be verified.

2. All computers on the network have the same address.

3. Only one computer can use the network.

4. These systems adapt to changes in network traffic.

The correct answer is: These systems adapt to changes in network traffic.

Packet-switching systems are designed to break data into smaller packets, which can be sent independently across the network. This approach enables them to efficiently adapt to changes in network traffic. The packets can take different paths to reach the destination, allowing the network to dynamically adjust to varying loads and congestions. This flexibility is a key advantage of packet-switching, as it improves the overall performance and reliability of data transmission. If one path is congested or unavailable, packets can be rerouted through other paths, ensuring that the data still reaches its destination efficiently and in an optimized manner. The other statements do not accurately describe packet-switching systems. For instance, while verification may occur, it is not a requirement for each packet. Each computer in a network does not share the same address; they are typically assigned unique identifiers. Finally, packet-switching allows multiple computers to share the network simultaneously rather than restricting access to just one.
