Glossary A access time The time period between the supply of an access signal and the output or acceptance of the data by the addressed system. Examples are the access times for DRAMs, SRAMs, hard drives, and CD-ROM drives. Hard drive access time is the time it takes for a computer to get data from the drive. A hard drive with an 11 ms access time is fast. A CD-ROM drive with a 280-ms access time is fast. ACPI Advanced Configuration and Power Interface.
APM Advanced Power Management. An API developed by Intel and Microsoft that allows developers to include power management in the BIOS. APM defines a layer between the hardware and the operating system that effectively shields the programmer from hardware details. application programs Software designed to perform specific functions or a group of functions, like solving business or mathematical problems. Examples of applications include word processing, communications, or database management.
B bad sector Part of a hard drive or diskette drive storage medium that doesn’t hold data. Formatting generally detects and marks these areas so they won’t be used. Certain utility programs do, too, and it is a good idea to run this type of utility occasionally to prevent data loss if the condition of the drive changes. bandwidth A measure of how much information something can carry. Specifically, data path times frequency.
bitmap Any occurrence where a single location in memory and a single pixel correspond. Usually applies to screen or printer output. .BMP files are bitmapped graphics files. bits per second (bps) A unit of transmission. Also called baud rate. block A contiguous section of bits considered as a whole, especially in memory. On a disk, the data in one sector; in modem data transfer, the bits between checksums. board Printed circuit board.
bus A parallel electrical pathway on the system board, connecting and shared by the parts of a computer system (especially the CPU, its support circuitry, memory, and expansion cards), used for transmitting data or electrical power from one device to another. Typically the lines in a bus are dedicated to specific functions, such as control lines, address lines, and data lines. Different bus architectures have different numbers and arrangements of these lines, and different names (for example, ISA, PCI).
CMOS Complementary Metal Oxide Semiconductor. A chip on the system board that contains nonvolatile memory. CMOS is backed up by an internal lithium battery that preserves clock/calendar data and system configuration parameters stored in CMOS. codec Coder-decoder.
DVD Digital versatile disc or digital video disc. A type of CD-ROM that holds a minimum of 4.7 GB, enough for a full-length movie. The DVD specification supports disks with capacities of from 4.7 GB to 17 GB and access rates of 600 Kbps to 1.3 Mbps. One of the features of DVD drives is that they are backward-compatible with CD-ROM disks. This means that DVD players can play old CD-ROMs, CD-I disks, and video CDs, as well as new DVDROMs. Newer DVD players can also read CD-R disks.
FTP File Transfer Protocol. A method of transferring files between two computers on a TCP/IP network (such as the Internet). “Anonymous FTP” (the most common usage on the Internet) allows a user to download files without having an account at the remote computer. function key The set of keys on the keyboard (usually F1 through F12) that let you get help and error message information or quickly select frequently used commands.
interrupt A signal from part of a system, such as an I/O device, asking to use the CPU. Interrupts are hierarchical, which prevents interrupts from interrupting each other. (Whichever interrupt has higher priority makes the other interrupt wait.) When the CPU receives an interrupt signal, it saves what it is doing, processes the routine associated with the interrupt, then returns to what it was doing. I/O address Input-Output address. How the CPU sees an I/O port.
M master Part of a two-sided communication that initiates commands (to a “slave” that carries out the commands). megabyte (MB) 1,048,576 bytes. memory Electronic storage area in a computer that retains information and programs. A computer has two types of memory: read-only memory (ROM) and random access memory (RAM). microprocessor A semiconductor central processing unit that is the principal component of a microcomputer.
O operating system Set of programs that manage the overall operation of the computer. overwrite Storing information at a location where information is already stored, thus destroying the original information.

port Any connection by which data can enter or leave a computer or peripheral. Provides the means for an interface between the microprocessor and external devices. A cable connector is usually plugged into the port to attach the device to the computer. processor In a computer, a functional unit that interprets and executes instructions. prompt A special symbol indicating the beginning of an input line. Also a message that appears on the screen indicating that the user must take a certain action.
S SEC Single-Edge Contact. The SEC cartridge containing the Pentium processor. See Slot 1. serial interface An interface that communicates information one bit at a time. serial printer A printer with a serial interface. SGRAM Synchronous Graphic Random Access Memory. A type of DRAM used increasingly on video adapters and graphics accelerators. Like SDRAM, SGRAM can synchronize itself with the CPU bus clock at speeds of up to 100 MHz.
system board The main printed circuit board inside the system unit into which other boards and major chip components, such as the system microprocessor, are connected. T tpi Tracks per inch. track Any of many concentric circular regions on a disk for storing data. Tracks are divided into sectors. One measure of storage density of a disk is tpi. U Ultra DMA A protocol developed by Quantum Corporation and Intel that supports burst mode data transfer rates of 33.3 MBps.
VRAM Video RAM. VRAM is special-purpose memory used by video adapters. Unlike conventional RAM, VRAM can be accessed by two different devices simultaneously. This enables a video adapter to access the VRAM for screen updates at the same time that the CPU provides new data. VRAM yields better graphics performance but is more expensive than normal RAM. A special type of VRAM, called Windows RAM (WRAM), yields even better performance than conventional VRAM. See SGRAM and WRAM.
