Technical Glossary -- (Kurt Smith)
Note: You may download the entries for this glossary here. If you wish to use this in your own Moodle course, first make a blank glossary and then follow the instructions for importing glossary entries here.
Kurt says:" A combo of ICT business and mobile phone terms. From my own entry and by incorporating some other glossaries. Anyone who has something similar let me know. Mobile phones in particular.

BERTAlso known as: Bit Error Rate Test
Bit Error Rate Test (BERT) is a device or test used to determine the Bit Error Rate for a particular transmission.
The test is used to discover how many received bits of data were in error, as a ratio of the total number of bits received. The result is usually a very small number, typically one in a billion (or 10 to the power minus 9).

Binary DigitAlso known as: Bit
Bit (binary digit) is the smallest unit of data used in digital information systems, being allocated only a single value of either 0 or 1, i.e. an "off" or an "on" state.
In the data communication field bits are counted using the decimal number system, and so other units of bits are kilobit (1,000 bits), Megabit (1,000,000 bits) and Gigabit (1,000,000,000 bits). The term "Bit" is derived from a combination of b(inary) and (dig)it

Bitmap GraphicA bitmap graphic, is a data file or structure representing a generally rectangular grid of pixels, or points of color, on a computer monitor, paper, or other display device. The color of each pixel is individually defined; images in the RGB color space, for instance, often consist of colored pixels defined by three bytesone byte each for red, green and blue. Less colorful images require less information per pixel; an image with only black and white pixels requires only a single bit for each pixel. Raster graphics are distinguished from vector graphics in that vector graphics represent an image through the use of geometric objects such as curves and polygons. | ||
Bitmap GraphicsA bit map (often spelled "bitmap") defines a display space and the color for each pixel or "bit" in the display space. A Graphics Interchange Format and a JPEG are examples of graphic image file types that contain bit maps. | ||
Bits Per SecondAlso known as: bps
Bits per Second (bps) is a commonly used unit of measurement in telecommunications for the rate or speed at which data is transferred. The bps indicates how many binary digits (the number of 0's and 1's) are transmitted or received in a serial form (one bit after another) each second.
In practice larger units are more convenient: one kilobit per second (kbps) is equal to 1,000 bps, one Megabit per second (Mbps) is equal to 1,000,000 bps or 1,000 kbps, one Gigabit per second (Gbps) is equal to 1,000,000,000 bps or 1,000 Mbps.
The bps is also an indication of a signal's bandwidth, and usually the higher the bps the greater is the signal bandwidth (a frequency measured in kHz or MHz).
The old measure of data speed was the Baud or "baud rate", which is the number of times a digital signal changes state each second. For a given digital signal Baud rate is almost always a lower figure than bps, but Baud Rate and bps are often wrongly interchanged
