Architecture
Pen drive consist of an electronic circuit board and a USB connector connects the drive to the computer. Pen Drive also known as a Flash memory is an example of NAND style storage device. It is a memory chip which holds the data. Data output is controlled by Crystal oscillator which produces 12 MHz clock signal in the device.
Most Pen Drives are covered with plastic, metal or rubber casing for insulation.
Advantages
Pen Drives are robust and scratch free thus ensuring maximum security for your data as compared to other traditional means of data storage. Many available PC software suites permit the launch of an operating system from the bootable pen drive.
