Yes, it is true that packet switching forms the basis for the internet. The packets can then be sent via the network devices to the recipient device, which reassembles them before using them.
For more effective transfer using multiple network devices, packet switching divides data into blocks or packets before transmitting it across digital networks. Each time a device sends a file to another, it divides the file into packets in order to ascertain the fastest way to transfer the data across the network at that specific moment.
The packets can then be sent via the network devices to the recipient device, which reassembles them before using them. Small data packets are sent between different networks using packet switching. These data "packets" or "chunks" enable quicker, more effective data transport.
When a user transfers a file over a network, it frequently travels in smaller data packets rather than all at once.
