Sneakernet

Sneakernet is a way of transferring data from one computer to another, without using the internet. It usually involves copying the data onto a storage device like a USB stick, hard drive, memory card, or floppy disk, and then carrying it on foot to the other computer. It's called "Sneakernet" because you wear sneakers (shoes) to carry the data from one place to another.
