Glossary-3
AutoYaST An installation program for SUSE Linux that automates the process of
configuring one or more servers.
B
bandwidth A measure of the volume of information that can be transmitted over a
communication link. Often used to describe the number of bits per second a
network can deliver.
baseboard management
controller (BMC) A device used to manage chassis environmental, configuration, and service
functions, and receive event data from other parts of the system. It receives
data through sensor interfaces and interprets this data by using the sensor data
record (SDR) to which it provides an interface. The BMC provides another
interface to the system event log (SEL). Typical functions of the BMC are to
measure processor temperature, power supply values, and cooling fan status.
The BMC can take autonomous action to preserve system integrity.
baud rate The rate at which information is transmitted between devices, for example,
between a terminal and a server.
bind In the Lightweight Directory Access Protocol (LDAP), refers to the
authentication process that LDAP requires when users access the LDAP
directory. Authentication occurs when the LDAP client binds to the LDAP
server.
BIOS (Basic
Input/Output System) System software that controls the loading of the operating system and testing
of hardware at system power on. BIOS is stored in read-only memory (ROM).
bits per second (bps) The unit of measurement for data transmission speed.
boot loader A program contained in read-only memory (ROM) that automatically runs at
system power-on to control the first stage of system initialization and
hardware tests. The boot loader then transfers control to a more complex
program that loads the operating system.
C
cache A copy of original data that is stored locally, often with instructions or the
most frequently accessed information. Cached data does not have to be
retrieved from a remote server again when requested. A cache increases
effective memory transfer rates and processor speed.
