The flash drive has become the part of every person who uses the computer. It is used to collect and store the data so that it can be opened where ever needed. The students always have their flash drives in their bags so that when ever they need lecture they can install it on their flash drives. The only problem with usb flash drive is that it captures viruses from the computer and if the same virus infected flash drive is plugged to another computer then the virus is transferred to that computer. How can this problem be resolved? The engineers are working day and night to resolve this problem. Moreover, the engineers are also trying to add the flash drive within the cell phones which means they will get the cell phone built in with usb drive like the cameras built in the cell phones. With the passage of time, the engineers are upgrading every kind of product. When the first cell phone manufactured with a built in black and white pictured camera, the world was amazed and this cell phone was sold at a large quantity.
