Usb Flash Memory
USB flash memory comes as a replacement for the hard drives. It does not have the mechanical limitations unlike the latter. It uses the technique of electrical programming and erasing. This can hold the data stored in the memory whether or not the device is powered. Hence it can be considered as an example of “non-volatile” memory. It also gives very fast read time. USB flash memory is preferred anytime as it can transfer files between computers by a simple insertion and a careful removal thereafter. It is one of the best ways to back up your data. Though it takes several forms such as memory cards, jump drives, the fundamental operating techniques are the same. It is enormously long-lasting, as it is able to withstand immense pressure, temperature extremes and even immersion in water. Digital cameras, camcorders etc use this type of flash memory to capture and hold data which can be transferred to any where any time.
