A file can have read-only status if: • Its read-only attribute is enabled. • It resides on a physically write-protected diskette or on a diskette in a write-protected drive. • It is located on a network in a directory to which the system administrator has assigned read-only rights to you. readme file A text file included with a software package or hardware product that contains information supplementing or updating the documentation for the software or hardware. Typically, readme files provide installation information, describe new product enhancements or corrections that have not yet been documented, and list known problems or other things you need to be aware of as you use the software or hardware. ROM Acronym for read-only memory. Your system contains some programs essential to its operation in ROM code. Unlike RAM, a ROM chip retains its contents even after you turn off your system.

RAM disk
A memory-resident program that emulates a hard
drive.
read-only file
A read-only file is one that you are prohibited from
editing or deleting. A file can have read-only status if:
•
Its read-only attribute is enabled.
•
It resides on a physically write-protected diskette or
on a diskette in a write-protected drive.
•
It is located on a network in a directory to which the
system administrator has assigned read-only rights
to you.
readme file
A text file included with a software package or hardware
product that contains information supplementing or
updating the documentation for the software or
hardware. Typically, readme files provide installation
information, describe new product enhancements or
corrections that have not yet been documented, and
list known problems or other things you need to be
aware of as you use the software or hardware.
ROM
Acronym for read-only memory. Your system contains
some programs essential to its operation in ROM code.
Unlike RAM, a ROM chip retains its contents even
after you turn off your system. Examples of code in
ROM include the program that initiates your system's
boot routine and the POST.
RPM
Abbreviation for Red Hat Package Manager.
schema
A collection of class definitions that describes managed
objects in a particular environment. A CIM schema is
a collection of class definitions used to represent
managed objects that are common to every
management environment, which is why CIM is called
the Common Information Model.
SCSI
Acronym for small computer system interface. An I/O
bus interface with faster data transmission rates than
standard ports. You can connect up to seven devices
(15 for some newer SCSI types) to one SCSI interface.

module are shared resources of the server modules in
the chassis. See modular system.
service tag number
A bar code label that identifies each system in the event
that you need to call for customer or technical support.
SMART
Acronym for Self-Monitoring Analysis and Reporting
Technology. A technology that allows hard drives to
report errors and failures to the system BIOS, which
then displays an error message on the screen. To take
advantage of this technology, you must have a SMART-
compliant hard drive and the proper support in the
system BIOS.
SMBIOS
Acronym for system management BIOS.

Protocol. SNMP, a popular network control and
monitoring protocol, is part of the original TCP/IP
protocol suite. SNMP provides the format in which
vital information about different network devices, such
as network servers or routers, can be sent to a
