While most system upgrades are now offered as downloads from the internet, if you can't get your computer to boot or your optical drive to spin, you certainly can't download the OS. That means you can reboot your system from the USB or even make a copy of your Windows, Mac, or Linux (hello there, Ubuntu) OS for use on other computers. The most common reason to transfer data from a CD/ISO to a USB drive is to make the USB bootable a live USB. While they were a huge upgrade from floppy discs, a flash drive with just 1 GB of storage can hold more data than the average CD. Just like the floppy disc disappeared because of its limited storage, the same is happening with CDs. There are a few reasons you'd want to do that, the first being that many laptop computers, in an effort to make them smaller and lighter, no longer come with optical (CD/DVD) drives. One technology question we hear is how to transfer ISO media data like an operating system burned onto an optical disc (CD/DVD) to a USB drive.
