B8ZS
A coding technique that transmits T1 data at 1.536Mbps by inserting the pattern 00011011, with BPV´s in the fourth and seventh positions, wherever ones density requirements are not met by the unmodified data. It requires the CSU to not remove bipolar violations, and works only where the phone company equipment can tolerate it. This allows 64Kbps channels on a T1 (for example) rather then the base 56Kbps.

RAM
RAM is a type of computer storage whose contents can be accessed in any order. This is in contrast to sequential memory devices such as magnetic tapes, discs and drums, in which the mechanical movement of the storage medium forces the computer to access data in a fixed order. It is usually implied that RAM can be both written to and read from, in contrast to read-only memory or ROM.
Computers use RAM to hold the program code and data during execution. In the first electronic computers, RAM wa... |

Depth-of-field
The area of sharpness in a picture, extending in front of and behind the plane of the subject, that is most precisely focused by the lens.
You can control depth of field by varying three factors: 1) the size of the aperture 2) the distance of the camera from the subject 3) the focal length of the lens. If you decrease the size of the Aperture, the depth of field increases; if you focus on a distant subject, depth of field will be greater than if you focus on a near subject; and if you... |
