Glossary 81GlossaryAC adapterThe AC (or alternating current) adapter regulates current coming into your computer from the wall outlet. The current at the wall outlet is alternating current and needs to be changed by the adapter to DC (direct current) before your computer can use it for power.ACPIACPI (Advanced Configuration and Power Interface)- a method for describing hardware interfaces in terms abstract enough to allow flexible and innovative hardware implementations and concrete enough to allow shrink-wrap OS code to use such hardware interfaces.BIOSBIOS stands for basic input/output system. The BIOS is software (often called firmware) that is independent of any operating system. It enables the computer to communicate with the screen, keyboard, and other peripheral devices without using programs on the hard disk. The BIOS on your computer is flash BIOS, which means that it has been recorded on a flash memory chip that can be updated if needed. BootTo start your computer. A cold boot resets the entire computer and runs through all computer self-tests. A warm boot clears out computer memory only.Boot diskA disk containing operating system programs required to start your computer. A boot disk can be a floppy disk, hard drive, or compact disc.ByteThe basic unit of measure for computer memory. A character—such as a letter of the alphabet—uses one byte of memory. Computer memory is often measured in kilobytes (1,024 bytes) or megabytes (1,048,576 bytes).Each byte is made up of eight bits. For more information on bytes and bits, see an introductory book on computers.Cache memoryCache is very fast, zero-wait-state memory located between the microprocessor and main memory. Cache reduces the average time required by the microprocessor to get the data it needs from the main memory by storing recently accessed data in the cache.Matrix II (Windows XP) - English.fm Page 81 Thursday, September 13, 2001 11:42 AM
82 Users ManualCardBusCardBus technology enables the computer to use 32-bit PC Cards. Hardware in the computer and the Windows operating system provide support for the 32-bit cards. The voltage of 32-bit cards (3.3 volts) is lower than that of 16-bit cards (5 volts). The 32-bit cards can transmit more data at a time than the 16-bit cards, thus increasing their speed. CMOS memoryCMOS (complementary metal oxide semiconductor) memory is powered by the CMOS battery. The System Setup settings and other parameters are maintained in CMOS memory. Even when you turn your computer off, the information in CMOS 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 programs can directly access this memory without using memory-management software.DiskThe device used by the computer to store and retrieve information. Disk can refer to 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 in a 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 data pass through the microprocessor. Using DMA can speed up system performance.DPMSDisplay Power Management Signalling. Displays or monitors that comply with this can be managed by the Power Management features found in the system setup.Floppy diskA removable disk, also called floppy or diskette.Matrix II (Windows XP) - English.fm Page 82 Thursday, September 13, 2001 11:42 AM
Glossary 83Hard driveAlso called fixed disk. A hard drive is connected to the computer and can be installed or removed. Data written to a hard drive remains until it is overwritten or corrupted.The 2.5-inch hard drive in your computer was designed for use in a notebook computer. Because hard drives in notebook computers are smaller than those in desktop computers, their maximum storage capacity may be less than that of desktop hard drives. However, because of their smaller size, the drives handle shock and vibration better than larger drives, which is important for a notebook computer.I/OInput/output. Refers to peripheral devices, such as printers, that are addressed through an I/O address.I/O addressI/O stands for input/output. Peripheral devices, such as printers, are addressed through the I/O port address.IRQ (interrupt request line)The IRQ is a hardware line that a device uses to signal the microprocessor when the device needs the microprocessor’s services. The number of IRQs is limited by industry standards. LCD (liquid-crystal display)The LCD screen on your computer differs from the display screen of a desktop monitor. Most desktop monitors use CRT (cathode-ray tube) displays, which work by moving an electron beam across phosphor dots on the back of the screen. The phosphor dots light up to show the image. LCDs use a liquid-crystal solution between two sheets of polarizing material. Electric current passing through the liquid aligns the crystals so that light can or cannot pass through them, creating an image.MB (megabyte)1,024 kilobytes.Megabit1,048,576 bits or about 128 kilobytes.Operating systemA program that supervises the computer's operation, including handling I/O. Application programs and users can request operating-system services. A user might request operation-system services to copy files or format a disk. An application program might use the operating system to obtain keyboard input, write data to a file, or write data to a screen.Matrix II (Windows XP) - English.fm Page 83 Thursday, September 13, 2001 11:42 AM
84 Users ManualPC CardPC Card stands for personal computer card. The Personal Computer Memory Card International Association (PCMCIA) defines the standards used to develop all PC Cards. PC Card types include: modems, Ethernet adapters, SCSI adapters, ATA cards, and memory cards.PC slotThe PC slot is the hardware slot in the computer where the PC Card is placed. PixelA pixel is an individual dot in a graphic displayed on your computer. The pixels are so close together that they look as though they are connected. An LCD screen displays thousands or millions of pixels. Plug and PlayA plug and play operating system automatically configures computer components to work with your system. With this type of operating system, you normally do not need to set jumpers on devices or set memory addresses or IRQs.RAM (random access memory)The computer's system memory, including conventional and extended memory. You can write to and read from RAM. Information stored in RAM is temporary, and is erased when the system is turned off.Refresh rateThe refresh rate is the rate at which the image on the LCD screen is rewritten to the screen. A fast refresh rate helps keep the image from flickering.ResolutionThe resolution is the sharpness or clarity of the image on your LCD screen. Resolution is measured by the number of pixels the computer’s screen can display. For example, a resolution of 800 x 600 means that the screen can display 800 pixels in row and can display 600 rows. The more pixels displayed, the higher the resolution and the better the image. ROM (read-only memory)Permanent computer memory dedicated to a particular function. For example, the instructions for starting the computer when you first turn on power are contained in ROM. You cannot write to ROM. (ROM is not the same as RAM).SectorAlso known as disk sector. The portion of a track that is numbered and can hold a specified number of characters (usually 512 KB).Matrix II (Windows XP) - English.fm Page 84 Thursday, September 13, 2001 11:42 AM
