Transcript of Thumbdrive
Here's a thumbdrive, there's a thumbdrive Thumbdrive capacity It can range from 128 MB to even 256 GB. Most people hold thumbdrives of 1 to 4GB now. They should cost below $100. Parts of a thumbdrive A flash drive consists of a small printed circuit board carrying the circuit elements and a USB connector, insulated electrically and protected inside a plastic, metal, or rubberized case which can be carried in a pocket or on a key chain, for example. The USB connector may be protected by a removable cap or by retracting into the body of the drive, although it is not likely to be damaged if unprotected. Most flash drives use a standard type-A USB connection allowing plugging into a port on a personal computer, but drives for other interfaces also exist. Power source of thumbdrives? Most USB flash drives draw their power from the USB connection, and do not require a battery. Some devices that combine the functionality of a digital audio player with flash-drive-type storage require a battery for the player function. The first thumbdrive Trek Technology and IBM began selling the first USB flash drives commercially in 2000. The Singaporean Trek Technology sold a model under the brand name "ThumbDrive", and IBM marketed the first such drives in North America with its product named the "DiskOnKey" -which was developed and manufactured by the Israeli company M-Systems. IBM's USB flash drive became available on December 15, 2000, and had a storage capacity of 8 MB, more than five times the capacity of the then-common floppy disks.
THUMBDRIVES Before USB Prior to USB drives, it was difficult and inconvenient to move large amounts of data from place to place. CD-writing technology was almost unavailable on personal computers until the late 1990s; the largest commonly-available portable storage media were floppy disks that could at best hold 1.44 megabytes.
Large files (over 1.44 MB) had to be split up across many floppy disks, or put on expensive and rarely-compatible high-density disks, such as Zip disks. Those required special, expensive hardware, which limited their popularity.
