2-stage shutter release
Commonly employed on digital cameras, 2-stage shutter release is a shutter release, that when pressed halfway, it activates the autofocus and the light meter of the camera, setting them to achieve correct focus and exposure. Holding the release at mid-course maintains the focusing point and allows for re-composition if desired. A further press on the shutter release takes the picture.

Refers to the number of bits that can be processed or transmitted in parallel, or the number of bits used for single element in a data format. The term is often applied to the following: microprocessor: indicates the width of the registers. A 32-bit microprocessor can process data and memory addresses that are represented by […]
- 3480, 3490
The IBM designation for families of half-inch magnetic tape drives typically used on mainframes and AS/400s. The 3480 drives use 18-track cartridges at 38000 bpi to yield 200MB. The 3490 uses built-in compression to obtain 400MB. The 3490e records 36 tracks and uses longer tape to hold 800MB. Tape libraries are available that hold from […]

A technology that supports photo-realistic graphics, full-motion video, and CD-quality sound. The first applications of this technology were stand-alone devices used for playing games, but the technology is beginning to find its way into PCs in the form of expansion boards.
- 3D Stereo technology
A technology that provides a more realistic view of 3D game visuals providing a more real 3D scene that allows you to better interact with the on-screen media. 3D Stereo technology on the PC requires both a software driver and a hardware device, such as stereo glasses, virtual reality hardware, or 3D displays. NVIDIA also […]
