Glossary Glossary AC Adapter A device which converts the AC voltage from a wall outlet to the DC voltage needed to power your LifeBook notebook. ACPI Advanced Configuration and Power Interface. An industry specification for the efficient handling of power consumption in mobile computers. ACPI determines how a computer's BIOS, operating system, and peripherals communicate with each other about power management. Active-Matrix Display A type of technology for making flat-panel displays which has a transistor or similar device for every pixel on the screen. ADSL Asymmetric Digital Subscriber Line. Technology for transporting high bit-rate services over ordinary phone lines. Auto/Airline Adapter A device which converts the DC voltage from an automobile cigarette lighter or aircraft DC power outlet to the DC voltage needed to power your LifeBook notebook. BIOS Basic Input-Output System. A program and set of default parameters stored in ROM which tests and operates your LifeBook notebook when you turn it on until it loads your installed operating system from disk. Information from the BIOS is transferred to the installed operating system to provide it with information on the configuration and status of the hardware. Bit An abbreviation for binary digit. A single piece of information which is either a one (1) or a zero (0). bps An abbreviation for bits per second. Used to describe data transfer rates. Boot To start-up a computer and load its operating system from disk, ROM or other storage media into RAM. Bus An electrical circuit which passes data between the CPU and the sub-assemblies inside your LifeBook notebook. Byte 8 bits of parallel binary information. Cache Memory A block of memory built into the micro-processor which is much faster to access than your system RAM and used in specially structured ways to make your overall data handling time faster. CardBus A faster, 32-bit version of the PC Card interface which offers performance similar to the 32-bit PCI architecture. CD-ROM Compact disc read only memory. This is a form of digital data storage which is read optically with a laser rather than a magnetic head. A typical CD-ROM can contain about 600MB of data and is not subject to heads crashing into the surface and destroying the data when there is a failure nor to wear from reading. CMS Code Morphing Software. Crusoe processor software architecture that results in longer battery life. For more information on CMS, click on the Technology link on the refer to the Transmeta website at: www.transmeta.com. Command An instruction which you give your operating system. Example: run a particular application or format a floppy disk. Configuration The combination of hardware and software that makes up your system and how it is allocated for use. Data The information a system stores and processes. DC Direct current. A voltage or current that does not fluctuate periodically with time. Default Value A pre programmed value to be used if you fail to set your own. DIMM Dual-in-line memory module. Disk A spinning platter of magnetic data storage media. If the platter is very stiff it is a hard drive, if it is highly flexible it is a floppy disk, if it is a floppy disk in a hard housing with a shutter it is commonly called a diskette. Disk Drive The hardware which spins the disk and has the heads and control circuitry for reading and writing the data on the disk. 101
