Explanation Contemporary communication systems are based on packet switching. This method involves breaking down data into small packets and sending them independently over a network. Each packet can take a different route to reach the destination, and they are reassembled at the receiving end. Packet switching allows for efficient use of network resources and enables simultaneous transmission of multiple data streams. It also provides robustness and flexibility, as packets can be rerouted in case of network congestion or failures.
Correct Answer
A. Π‘Π° ΠΊΠΎΠΌΡΡΠ°ΡΠΈΡΠΎΠΌ ΠΊΠ°Π½Π°Π»Π°, ΠΏΠΎΡΡΠΊΠ°, ΠΏΠ°ΠΊΠ΅ΡΠ°
Explanation The correct answer states that there are communication networks with channel switching, message switching, and packet switching. This suggests that there are different types of communication networks based on the method of transmitting data, such as switching channels, messages, or packets.
Explanation A typical circuit-switched network is a telephone network. This is because in a circuit-switched network, a dedicated communication path is established between the sender and receiver for the duration of the call, similar to how a traditional telephone call works. In a circuit-switched network, the resources are reserved for the entire duration of the call, ensuring a reliable and consistent connection. This is in contrast to packet-switched networks like the internet or Ethernet, where data is divided into packets and sent separately, allowing for more efficient use of network resources. A cable distribution system typically refers to the distribution of television signals through cable networks and is not typically considered a type of circuit-switched network.
