A Megabyte (MB) is 1,000,000 bytes (strictly 220 = 1,048,576 bytes)

A Kilobyte is 1,000 bytes (strictly 210 = 1,024 bytes)

A Gigabyte (GB) is 1,000,000,000 (one thousand million) bytes (strictly 230 = 1,073,741,824 bytes).

Data, usually textual, associated with an asset for the purpose of describing its various attributes. These might be such things as who created the asset and when, a title, caption and full description, keywords or tags, and so on.

Descriptive metadata might be stored within the asset file itself, using for example the IPTC standard. These are known as embedded metadata.

In the case of digital images there will usually be a wide range of technical data, such as the make and model of the camera, the shutter speed and aperture setting used, etc… These data usually conform to the EXIF standard.

In the context of digital asset management and online libraries, good systems will be able to extract these data and map them to fields in the database to enable them, if required, to be searchable and displayed. Similarly, it should be possible from within a digital asset management system to overwrite or create new embedded metadata.
