3. It involves messages routed in their entirety, one hop at a time. It is a message sent as complete unit. It evolved from circuit switching and was the precursor of packet switching.

• packet switching

• circuit switching

• message switching

• virtual circuits

4. It transmits data across digital networks by breaking it down into blocks or packets for more efficient transfer using various network devices. It is a mode of transmission in which the message is broken into number of parts.
