USB flash drive

USB flash drive is a data storage devices that consists of flash memory with an integrated universal serial bus (USB) interface. 

USB flash drives are typically removable and rewritable, and physically much smaller than a floppy disk.
USB flash drives are often used for the same purposes for which floppy disks or CD-ROMs were used. 
They are smaller, faster, have thousands of times more capacity, and are more durable and reliable .

USB Flash drives use the USB mass storage standard, supported natively by modern operating systems such as LinuxMac OS XWindows, and other Unix-like systems. 
USB drives with USB 2.0 support can store more data and transfer faster than a much larger optical disc drives like CD-RW or DVD-RW drives.

A flash drive consists of a small printed circuit board carrying the circuit elements and a USB connector,for example like key chain.
