Thumb Drive
A Thumb Drive is one name for a USB Flash Chip. Other nicknames are Jump Drive and USB Keychain. The Thumb Drive comes in various sizes, like 256mb, and plugs into a computer's USB port. It's like having a pocket hard drive.
Thumbnail
A Thumbnail is a small version of a larger picture. Many browsing and editing programs use thumbnails to index a picture collection. Some programs will even generate Contact Sheets, which are basically page after page of thumbnails showing the entire collection or directory.
Uploading
Uploading is the opposite of downloading. Uploading involves sending a file from your computer to another system, either through a cable or over the Internet.
USB
USB stands for Universal Serial Bus. It's an industry standard for connecting things to computers. Most digital cameras and chip readers use a USB cable to connect to the computer. USB 2.0 is a newer and faster standard, but not every computer can handle the 2.0 speeds yet.
White Balance
White Balance is a camera setting used to compensate for changes in the color of light. Some artificial lights "tint" the color they project, so the camera's white balance setting is used to balance this back to a more normal color cast. If the camera's white balance was incorrect, then the photo editor has to account for this by changing the color scale. The program will use an area that was supposed to be white as the starting point, and will remap every other color in the picture accordingly.
Wizard
A Wizard in computer terms is a program that walks you through a process step by step. For example, a scanning wizard might ask a series of questions on color vs. black and white, automatic scratch removal, and image resolution, before it actually triggers the scanner.
