The term USB means Universal Serial Bus. As the name Serial Bus indicates USB is a standard to send data one bit at a time, which means it communicates via serial communication or in other word data is send sequentially. USB can connect computer peripherals such as mice, keyboards, PDAs, joysticks, scanners, digital cameras, printers, modems, mobile phones, personal media players, bluetooth devices, flash drives, as well as external hard drives. Now all USB drives become so popular and almost all new computers have more than one USB port.
Out of USB drives the flash drive or keychain drive or also called jump drive is a plug-and-play portable storage device. In this country (Bangladesh) we call it pen drive. USB flash drive allows hot swapping after we attach it to any computer we don't need reboot the machine. Without reboot we can work with it. Unlike other removable storage USA flash drive does not require batteries or an external power supply. It also is not platform dependent. With data transfer and storing facility many manufacturers offer various types of function such as password protection, and downloadable drivers that allow the device to be compatible with older systems that do not have USB ports.

2)Cheaper- think about why we don't use floopy drive. With storing capacity of 1.44M floppy drive how much we would need to pay to get 1G space and how much space in our room they would occupied? Simply a 25 gram weighted flash drive can do full fill everything.
3)Faster- Pen drive is much faster than Floppy drive, CD.
4)Durable- Many companies offers life time warranty of flash drive unlike hard disk or any other storages.
Most flash drives ship preformatted with the FAT or FAT 32 file system unlike hard disk which comes as RAW partitions. The reason to ship with FAT or FAT32 is because of the ubiquity of these file systems. These file system allows the drive to be accessed on virtually any host device with USB support.
