What type of network does not use a dedicated connection between endpoints?

Packet-switched networks do not use a dedicated connection between endpoints, and this is a fundamental characteristic that distinguishes them from other network types. In a packet-switched network, data is broken down into packets that are sent independently across the network. Each packet can take different paths to reach its destination, where they are reassembled in the correct order. This method allows for efficient use of bandwidth and enables the network to accommodate multiple users simultaneously without pre-allocating resources.

On the other hand, circuit-switched networks establish a dedicated connection for the duration of a communication session, reserving bandwidth exclusively for that session. Broadcast networks allow multiple devices to receive the same data simultaneously over a shared medium, but still rely on physical connections. Mesh networks connect multiple nodes directly to one another, which can also imply dedicated paths. However, packet-switched networks are noted for their flexibility and efficiency in handling varying data traffic without the constraints of dedicated connections.
