color depth A term used to describe the number of bits used to represent colors for each pixel in a display. There are four common color depths: 8-bit (256 colors), 16-bit (High Color), and 24-bit and 32-bit (True Color). In 24-bit and higher, over 16 million colors can be represented.

D

daemon A process that runs in the background and performs a specified operation at predefined times or in response to certain events.

daughter card Optional card that attaches to the SunPCi motherboard. Provides a 1394 (Firewire) port as well as two additional USB ports. Also known as the USB/Firewire backplate.

disk growing Utility provided in the SunPCi software that allows enlargement of the emulated disk. The size of the emulated disk is limited to the resources available on the Solaris filesystem.

driver A program that controls a device. Drivers are typically included in the operating system or software, or are shipped with the software itself.

E

emulated drive File on the Solaris filesystem that the SunPCi hardware sees as an actual hard disk. Since it is an actual Solaris file, it can be freely copied and moved.

external monitor Actual physical monitor. A SunPCi session is displayed on a separate monitor attached directly to the SunPCi card. See also internal monitor.

F

FAT (File Allocation Table) Filesystem used by MS DOS and other Windows-based operating systems to organize and manage files. Stores disk files in 16-Kbyte blocks.

FAT32 A derivative of the FAT filesystem. Supports smaller cluster size and larger volumes than FAT, which results in more efficient space allocation. Stores disk files in 32-Kbyte blocks.
