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...

Abbreviated as PDL, a language for describing the layout and contents of a printed page. The best-known PDLs are Adobe PostScript and Hewlett-Packard PCL (Printer Control Language), both of which are used to control laser printers.

Both PostScript and modern versions of PCL are object-oriented, meaning that they describe a page in terms of geometrical objects such as lines, arcs, and circles.

Used in conjunction with the Internet Protocol (IP) to transmit information over the Internet in the form of units.

While IP takes care of handling the actual delivery of the data, TCP takes care of keeping track of the packets that a message is divided into for efficient routing through the Internet. For example, when a web page is downloaded from a web server, the TCP program layer in that server divides the file into packets, numbers the packets, and then forwards them individually to the ...

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.

In 1991, the NCSA introduced NCSA Mosaic, the first readily-available graphical Web Browser that vitrually kickstarted the dot.com revolution. It may not look like much now - but it is interesting to consider how similar modern browsers look to the original.
