Breaking Data Into Pieces
When you send data across a network, it doesn't travel as one big lump. It's broken into small chunks called packets. Imagine sending a 1000-page book through the post - you wouldn't send it as one massive parcel! You'd break it into smaller packages, send them separately (maybe different routes), and reassemble at destination. Packet switching works the same way: data split into packets, each packet finds its own route through the network, packets reassembled at destination. This makes networks faster, more efficient, and more reliable!
