CompactFlash- a flash memory format introduced in 1994 by SanDisk Corporation. At 36.4 x 42.8 x 3.3 mm, CompactFlash (CF) cards are larger than other flash formats, but have become very popular for storage in digital cameras. Appearing to the camera as a hard disk, CompactFlash uses the PC Card/ATA interface, but with 50 pins instead of 68. Cards support both 3.3 and 5v operation. CF cards plug into a CF socket or, with an adapter, into a standard Type II PC Card slot. There are two main subdivisions of CF cards, Type I and the slightly thicker Type II cards. There are two, soon to be three, main speeds of cards including the original CF, CF High Speed (using CF+/CF2.0), and a even faster CF3.0 standard that is being adopted as of 2005. The write speed of CompactFlash cards is designated as a multiple of 150 kilobytes per second. For example, 4x = 600KB/sec; 40x = 6MB/sec; 80x = 12MB/sec.
Compaq- (Compaq Computer Corporation) a leading computer manufacturer that designs, develops and markets computers and computer software.
