digital camera

Definition:

A digital camera is a camera that stores its pictures digitally, usually on a memory card inside the camera. Digital cameras do not use film and the resulting pictures taken with the camera do not need to be developed. Since the pictures are stored digitally on the camera's memory card, the pictures can be transferred directly to a computer by taking the memory card out of the camera and inserting directly into a computer' memory card reader or by connecting the camera to the computer using a USB cable.

Once the digital pictures are on a computer they can be edited (cropped, red-eye removal, etc.) and then emailed as attachments or uploaded to a photo sharing Internet web site. Many local stores including drug stores and grocery stores now allow you to insert your digital camera's memory card directly into a kiosk to instantly receive prints from your digital pictures.

Here's a word you may not know...

buffering

Buffering is a term usually used in conjunction with streaming. When a large audio or video file is streamed to a computer from the Internet, the beginning portion of the audio or video file must be downloaded to the computer before it can start playing. The part of the file that has downloaded but not yet been played is referred to as the buffer.

If, while listening to the audio or watching the video, the computer uses up all of its buffer, the audio or video clip must stop playing while more content is downloaded to the buffer before audio or video playing can resume.
