Packet Switching GCSE Quiz

What is packet switching?

• A method of transmitting data by sending it all at once over the network.

• A method of transmitting data by encrypting it and sending it over the network.

• A method of transmitting data by converting it into audio signals and sending it over the network.

• A method of transmitting data by dividing it into small packets and sending them independently over the network.

Which network technology uses packet switching?

What happens if a packet is lost during transmission in packet switching?

• The lost packet will be retransmitted by the sender.

• The lost packet will cause the entire transmission to fail.
