A USB flash drive consists of a NAND-type flash memory data storage device integrated with a USB (universal serial bus) interface. USB flash drives are typically removable and rewritable, much smaller than a floppy disk (1 to 4 inches or 2.5 to 10 cm), and most USB flash drives weigh less than an ounce (28g). Storage capacities typically range from 64 MB to 128 GB with steady improvements in size and price per gigabyte. Some allow 1 million write or erase cycles and have 10-year data retention, connected by USB 1.1 or USB 2.0.
USB flash drives offer potential advantages over other portable storage devices, particularly floppy disks or the COMPACT DISC (CD). They have a more compact shape, operate faster, hold much more data, have a more durable design, and operate more reliably due to their lack of moving parts.
Additionally, it has become increasingly common for computers to be sold without floppy disk drives. USB ports, on the other hand, appear on almost every current[update] mainstream PC and laptop. These types of drives use the USB mass storage standard, supported natively by modern operating systems such as Windows, Mac OS X, Linux, and other Unix-like systems.
Nothing actually moves in a flash drive: the term drive persists because computers read and write flash-drive data using the same system commands as for a mechanical disk drive, with the storage appearing to the computer operating system and user interface as just another drive.
A flash drive consists of a small printed circuit board protected inside a plastic, metal, or rubberised case, robust enough for carrying with no additional protection—in a pocket or on a key chain, for example. The USB connector is protected by a removable cap or by retracting into the body of the drive, although it is not liable to be damaged if exposed. Most flash drives use a standard type-A USB connection allowing plugging into a port on a personal computer.You can transfer photos from your camera directly to your USB Flash Drive as well.
There are numerous solutions for importing digital pictures from your camera to your hard drive. I typically just connect my digital camera to my PC and copy the files over using Windows Scanner and Camera Wizard.
If you prefer to use an external application, Google's Picasa is an excellent solution. So is Photobucket, and Flickr. In addition to being a convenient way to manage your images, Picasa also includes common photo editing functions and assists in uploading images to the Web or creating slideshows on your local system.
One of my favorite features of Picasa is a timeline that shows when images were taken in relation to all your other images (which only works if your digital camera is set to the correct date). Picasa is free for Windows 2000, Windows XP, and Linux.
After you take pictures with your digital camera, you'll want to copy the pictures from your camera to your computer so you can print them, share them with others, and back them up for safe keeping. Once your pictures are on your computer, you can erase them from your camera, freeing up memory so you can take more pictures. You can also view your pictures on a larger screen and decide which ones are worth keeping.
Some digital cameras come with software that helps you copy pictures from your camera to your computer. You can use this software, but you don't have to.
Windows XP can copy pictures to your computer without requiring additional software.
Windows XP opens a Windows Explorer window showing the pictures you downloaded from your camera. Your camera's memory card is now clean and ready to store new pictures. If you connected your camera to your computer using a USB cable, disconnect your camera. If you used a memory card reader, return the memory card to the camera.
Digital cameras and computers have revolutionized photography. Whether photography is your profession or a hobby, the ability to transfer your pictures from your camera to a flash drive without needing a computer is a bonus. Purchase a few accessible and inexpensive devices, or a full-featured tool, in order to quickly move your images to your flash drive and immediately continue taking pictures.
Transferring Photos from memory card to USB Flash Drive
(We don't have a memory card reader in the lab)
You can transfer photos from your camera directly to your USB Flash Drive as well. Demonstrate. Requires 2 USB ports.
Copying files and folders to a CD
- Insert a blank CD into the CD recorder. Use one of the following:
- Recordable compact disc (CD-R)
- Rewritable compact disc (CD-RW)
With rewritable CDs, you can copy data to and erase data from the CD multiple times.
- Click Start, and then click My Computer.
- Click the files or folders that you want to copy to the CD.
- To select more than one file, hold down the CTRL key while you click the files you want. Then, under File and Folder Tasks, click Copy this file, Copy this folder, or Copy the selected items.
- If the files are located in My Pictures, under Picture Tasks, click Copy to CD or Copy all items to CD, and then go to Step 5.
- Do not try to copy more files to the CD than it will hold. Check the CD packaging to see the capacity of each CD. For files too large to fit on a CD, you can copy files to a recordable DVD (DVD-R or DVD+R) or rewritable DVD (DVD-RW or DVD+RW). However, Windows XP does not support copying to a DVD, so you have to use DVD authoring software.
- Make sure that you have enough disk space on your hard disk to store the temporary files that are created during the CD-writing process. For a standard CD, Windows reserves up to 700 megabytes (MB) of the available free space. For a high-capacity CD, Windows reserves up to 1 gigabyte (GB) of the available free space.
- After you copy files or folders to the CD, you can view the CD to confirm that the files have been copied.
