A number used by accountants to identify expenses associated with a particular department. You can add a GL Code to each of the nodes of your hierarchy and use them for allocating costs and other reporting.

Gigabyte (G or GB)

A unit of measure for a chunk of data totaling about 1 billion bytes (1,073,741,824 bytes, or 2 to the 30th power, to be exact, because bytes are calculated as binary numbers, based on the number 2). The following table shows standard measures of data based on bytes:

Term Abbreviation Approximate Value Precise Binary Value
Byte B 8 bits  
Kilobyte K or KB 1,000 bytes 1,024 bytes or 2 to the 10th power
Megabyte M or MB 1 million bytes 1,048,576 bytes or 2 to the 20th power
Gigabyte G or GB 1 billion bytes 1,073,741,824 bytes or 2 to the 30th power
Terabyte TB 1 trillion bytes 1,099,511,627,776 bytes or 2 to the 40th power
Graphics Interchange Format (GIF)

A form of data file that contains color images and background graphics. Most of the color images you find on the Web are GIF files. Once the most popular format for online color photos, this compact file format is ideal for graphics that use only a few hues or consist of line drawings. It has lost ground to the JPEG format for photos, however, because GIF images support 256 colors, while JPEGs can contain some 16-24 million colors and can look almost as good as photographs. Some still consider GIF better than JPEG for simpler images.
