Application of USB Flash Disk

Inevitability of USB Flash Drive

With the rapid development of computer hardware, peripherals increasing number of keyboard, mouse, modem, printer, scanner is already well known, digital camera, MP3 player after another, so much equipments, how to access the personal computer? USB is generated for this purpose. USB is a computer peripheral device connected to standardized single interface specification developed by Intel, NEC, Compaq, DEC, IBM, Microsoft, Northern Telecom, Contact.
