CLFI name for a Digital Signal 1 (DS1) a transmission line with bandwidth sufficient to carry 24 DS0 (64 or 56 Kbps depending on coding) channels.

Because of overhead a T1 being delivered by a provider for data communications usually provides 1.344Mbps of bandwidth, whereas the T1 consumes 1.544Mbps of bandwidth. With B8ZS coding the T1 can provide 1.536MBps of bandwidth (this has become common in modern networks)

The T1 was frequently thought of as the basic building block in Telecommunic...

A generic name for various kinds of dynamic random access memory: DRAM that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time. The speed of SDRAM is rated in MHz rather than in nanoseconds (ns). This makes it easier to compare the bus speed and the RAM chip speed. You can convert the RAM clock speed to nanoseconds by dividing the chip speed into 1 billion ns (which is on...

A Page Description Language (PDL) developed by Adobe Systems. PostScript is primarily a language for printing documents on laser printers, but it can be adapted to produce images on other types of devices. PostScript is the standard for desktop publishing because it is supported by imagesetters, the very high-resolution printers used by service bureaus to produce camera-ready copy.

PostScript is an object-oriented language, meaning that it treats images, including fonts, as collections of ge...

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...

Making several exposures, using different settings (initially this was restricted to exposure but with digital photography can also include white balance and quality). Bracketing allows for error and permits selection of the best exposure after development.

Most professional photographers will always bracket photos where you only have one chance to capture the moment - weddings for example.

A set of detailed rules for communication between a client and server. This protocol is the foundation of data transmission on the www
