Packet-Switched Network What is a Packet-Switched Network? A packet-switched network transmits data by breaking it into smaller packets that are sent independently and reassembled at the destination. It ensures efficient and flexible data transmission. Explanation Unlike circuit-switched networks, packet-switched networks optimise bandwidth by dynamically routing packets through the most efficient paths. They are commonly used in the internet and mobile networks. Practical Example of a Packet-Switched Network A VoIP call uses a packet-switched network to transmit voice data in real-time, ensuring efficient use of network resources.
