Imagine a computer talking to two others on the internet simultaneously. It achieves this by switching back and forth between the two destinations, making the communication smooth and efficient. That's how computers handle multitasking in a network. This switching is taken care by the Operating System.
A host can send and receive and process packets in any order.
If a host needs to transit data to two others at once , it can alternate between the destinations in outgoing packets. Breaking messages into smaller units also makes it easier to detect and compensate fro errors in transmission
host can transmit data to two others at once by breaking the data into packets and alternating between the destinations in outgoing packet, basically switching between machines.
