Which of the following technologies relies on dynamic allocation of data packets?

1. Frame relay

2. Circuit-switched networks

3. Packet switching

4. Store-and-forward technology

The correct answer is: Packet switching

The technology that relies on dynamic allocation of data packets is packet switching. This approach allows for the efficient transmission of data over a network by breaking down messages into smaller packets, which are then sent independently. Each packet can take different paths through the network based on the current traffic conditions and other factors, making the process highly adaptable and efficient. In packet switching, packets are dynamically routed through the network, meaning that they can be sent through different paths depending on the network's congestion or availability of resources at any given moment. This flexibility is a key advantage because it maximizes the utilization of network resources and minimizes delays. Frame relay and store-and-forward technology are also related to data transmission, but they do not primarily rely on the dynamic allocation of packets in the same way that packet switching does. Frame relay is a specific type of packet-switching network that is designed for efficient data transfer but does not utilize the same level of dynamic routing. Store-and-forward technology involves temporarily holding packets at a node before forwarding them; while it can work with packet-switching concepts, it is not synonymous with the dynamic allocation characteristic inherent in pure packet switching. Circuit-switched networks, meanwhile, allocate a fixed circuit for a communication session, which is not flexible or dynamic like packet
