USB Flash Drives (key drives) come in a variety of shapes and colors (one example is shown below). They store data on flash memory chips. The storage capacity varies, but anything from 16 MB to over a gigabyte are available.
The cap of this flash drive has been removed to expose the USB connector, ready to be inserted into a USB port on a computer. Like floppies and zip disks, flash drives can be formatted for either Macs or PCs, but formatting them for PCs allows them to be used on both (since Macs can read both Mac and PC formats).
