Active Matrix Display
A type of flat-panel display in which the screen is refreshed
more frequently than in conventional passive-matrix displays.
The most common type of active-matrix display is based on a
technology known as TFT (thin film transistor). The two
terms, active matrix and TFT, are often used
interchangeably.
ACPI
Advanced Configuration Power Interface. A standard that
regulates all Plug-and-Play devices.
APM
Advanced Power Management, an operating and application
level of power management, your notebook is fully
compatible to this.
Application Program
A complete, self-contained program that performs a specific
function directly for the user.
BIOS
Basic Input/Output System. Programs that are permanently
stored in the system board’s EEPROM chips providing
functions such as the power-on self test (POST). In the
manual we refer the BIOS as Setup. To modify the BIOS
settings press [Delete] when you start your notebook, for
more information see ”Chapter Three - Running BIOS Setup.”
Bit
A binary digit, the smallest unit used in a computer, it takes 8
bits to make a byte.
Boot
To start the computer system and load the operating system.
Bus
The set of address or data lines used to transfer information
between different components within a computer (such as
memory, the microprocessor, and the expansion slots). The
width of the bus or the number of parallel connectors,
determines the size in bits of the largest data item that it can
carry. Your notebook uses both ISA and PCI buses; the PCI
bus is much faster (VGA, PCMCIA and IDE).
Byte
8 bits of memory.
Cache
Small, fast, local storage for frequently accessed instructions
and data to provide the processor with the fastest stream of
information possible, while keeping main memory current.
Can also be used for a local copy of data accessible over a
network, and more.
Cardbus
A 32-bit extension of the 16-bit PC Card peripheral interface,
widely known as the PCMCIA interface for its parent
organization, the Personal Computer Memory Card
International Association.
CD-ROM
Compact Disc-Read Only Memory. An information (data)
storage device that uses compact disc technology. CDs can
store over 650 MB. Until recently they could not be written to,
hence the appellation “Read Only.” The new CD-W format,
however, allows for repeatable reformatting and rewriting of a
single CD (with applicable hardware).
CD-ROM Drive
The device that reads CD-ROM discs.
CMOS
Complementary Metal Oxide Semiconductor. A logic circuit
family that uses very little power. It stores system setup
information including system hardware settings. Sometimes
used to store information by applying constant, uninterrupted
power through the use of an external battery. The BIOS code
is saved here.
