TYPE (I, II and III)
BMP
JPEGThis is the name of a card currently being standardized by the Japan Electronic Industry Association (JEIDA) and PCMCIA
(Personal Computer Memory Card Interface Association) of the United States.
A type of PC card.  ATA was originally a type of interface between computers and fixed disk devices.  The ATA card is a standard
card-type recording medium.
CompactFlash card is a small removable card conforming to ATA specifications. It is one-fourth the volume of a PCMCIA card.
PCMCIA 2.1 PC cards are divided into three types according to their thickness:  Type I (3.3 mm), Type II (5.0 mm) and Type III
(10.5 mm).
A type of image format.  The standard Windows Bit Map format used for MS-DOS/Windows-compatible computers.
A type of image format.  JPEG is the abbreviation of Joint Photographic Experts Group.  JPEG compression offers efficient
data storage.  The data not required for displaying the image is identified and deleted.  Since the data is deleted, JPEG
algorithms are said to be irreversible.  This means that once the image is compressed, the decompressed image it is not the
same as the original image.
