Glossary 101CardBusCardBus technology enables the computer to use 32-bit PC Cards. Hardware inthe computer and the Windows operating system provide support for the 32-bitcards. The voltage of 32-bit cards (3.3 volts) is lower than that of 16-bit cards (5volts). The 32-bit cards can transmit more data at a time than the 16-bit cards, thusincreasing their speed.CMOS memoryCMOS (complementary metal oxide semiconductor) memory is powered by theCMOS battery. The System Setup settings and other parameters are maintained inCMOS memory. Even when you turn your computer off, the information inCMOS memory is saved.COM portCOM stands for communication. COM ports are the serial ports in your computer.Compact DiscA compact disc (CD).Conventional memoryThe first 640 KB of system memory. Operating systems and application programscan directly access this memory without using memory-management software.DiskThe device used by the computer to store and retrieve information. Disk can referto a floppy disk, hard disk, or RAM disk.Disk cacheA software device that accumulates copies of recently used disk sectors in RAM.The application program can then read these copies without accessing the disk.This, in turn, speeds up the performance of the application.A cache is a buffer for transferring disk sectors in and out of RAM. Data stored ina disk cache is a copy of data already stored on the physical disk.DMA (direct memory access)A method of transferring data from a device to memory without having the datapass through the microprocessor. Using DMA can speed up system performance.DPMSDisplay Power Management Signalling. Displays or monitors that comply withthis can be managed by the Power Management features found in the systemsetup.Floppy diskA removable disk, also called floppy or diskette.
