This allows a USB flash drive containing media files in a variety of formats to be played directly on devices which support the format. The USB plug is usually retractable or fitted with a removable protective cap. In contrast to SD cards , write protection on USB flash drives when available is connected to the drive circuitry, and is handled by the drive itself instead of the host on SD cards handling of the write-protection notch is optional. Digital audio files can be transported from one computer to another like any other file, and played on a compatible media player with caveats for DRM -locked files. In addition to five high- bitrate MP3s , it also included a video, pictures, lyrics, and guitar tablature. However, because a flash drive appears as a USB-connected hard drive to the host system, the drive can be reformatted to any file system supported by the host operating system.

For the USB flash drive brand of the same name, see Lexar. U3 also provides a software framework for independent software vendors interested in their platform.

To address this, as well as space limitations, some developers have produced special versions of operating systems such as Linux in Live USB  or commonplace applications such as Mozilla K707i designed to run from flash drives.

USB flash drives are often used for storage, data back-up and transfer of computer files. Flash drives are used to carry applications that run on the host computer without requiring installation.
However, any USB flash drive can be used in this arcade game. In either case, the drive is removed at night and taken offsite.
Ravea compilation album released by the Kiss Network in April Usually, such drives will be custom-stamped with a company’s logoas a form of advertising. Storage capacities in this range have traditionally been considered to offer adequate space, because they allow enough space for both the operating system software and some free space for the user’s data.
Original flash memory designs had very limited estimated lifetimes. While any standalone application can in principle be used this way, many programs store data, configuration information, etc.
This feature, which gradually became less common, consists of a switch on the housing of the drive itself, that prevents the host computer from writing or modifying data on the drive. For the fictional propulsion system, see Jump drive.
Please help this article by looking for better, more reliable sources. You can also backup contacts and messages onto the phones SIM card.

The flash drives present a simple block-structured logical unit to the host operating system, hiding the individual complex implementation details of the various underlying flash memory devices.
Compared with floppy disks or CDsthey are smaller, faster, have significantly more capacity, and are more durable due to a lack of moving parts. As of software revision 21 R21players can also store custom songs and play them on any machine on which this feature is enabled. USB flash drives with images of dragons, cats or aliens are very popular in Asia. The password can then be changed, or it may be possible to crack the password with a password cracking program and gain full control over the computer.
Drives typically use the USB mass storage device class to communicate with the host. Pua Khein-Seng from Malaysia has been credited with this invention.
Learn how and when to remove these template messages. Many companies make small solid-state digital audio playersessentially producing flash drives with sound output and a isb user interface. However, there are USB drives with fingerprint scanners which use controllers that allow access to protected data without any authentication.
Flash drives also have disadvantages. The ubiquity of SD cards is such that, circadue to economies of scaletheir price is now less than an equivalent-capacity USB flash drive, even with flaxh added cost of a USB SD card reader. Counterfeit USB flash drives are sometimes sold with claims of having higher capacities than they actually have.
The development of high-speed serial data interfaces such as USB made semiconductor memory ush with serially accessed storage viable, and the simultaneous development of small, high-speed, low-power microprocessor k77i allowed this to be incorporated into extremely compact systems.
In tlash to SD cardswrite protection on USB flash drives when available is connected to the drive circuitry, and is handled by the drive itself instead of the host on SD cards handling of the write-protection notch is optional. Archived from the original on 8 September You can back up your files by dragging and dropping them from the removable drive to the computer folder in which you want to store them.
Also, HP has introduced a USB floppy drive keywhich is an ordinary USB flash drive with additional flasu for performing floppy drive emulation, allowing its usage for updating system firmware where direct usage of USB flash drives is not supported.
