probe

An electronic sensor for measuring a quantity or determining system state at a particular point within a system. Server Administrator can monitor temperature, voltage,fan,memory,currentandchassisintrusionprobes. The probes provide a snapshot of the measured quantity (such as the temperature at a particular place and time) or state (a chassis intrusion has or has not occurred).

program diskette set

The set of diskettes from which you can perform a complete installation of an operating system or application program. When you reconfigure a program, you often need its program diskette set.

protected mode

An operating mode supported by 80286 or higher microprocessors, protected mode allows operating systems to implement:

•A memory address space of 16 MB (80286 microprocessor) to 4 GB (Intel386 or higher microprocessor)

•Multitasking

•Virtual memory, a method for increasing addressable memory by using the hard drive

The Windows NT, Windows 2000, Windows XP, OS/2®, and UNIX® 32-bit operating systems run in protected mode. MS-DOS cannot run in protected mode; however, some programs that you can start from MS-DOS, such as the Windows operating system, are able to put the computer into protected mode.

provider

A provider is an extension of a CIM schema that communicates with managed objects and accesses data and event notifications from a variety of sources. Providers forward this information to the CIM Object Manager for integration and interpretation.

PS

Abbreviation for power supply.

PS/2

Abbreviation for Personal System/2.

PXE

Abbreviation for Pre-boot eXecution Environment.

QFP

Acronym for quad flat pack.

RAC

Acronym for remote access controller. Dell OpenManage Server Administrator supports all RACs. These include the DRAC II, DRAC III, DRAC III/XT, ERA, and ERA/O.

RAID

Acronym for redundant array of independent drives.

RAM

Acronym for random-access memory. The computer's primary temporary storage area for program instructions and data. Each location in RAM is identified by a number called a memoryaddress.Any information stored in RAM is lost when you turn off your computer.

RAMBUS

Acronym for Rambus DRAM, a type of memory (DRAM) developed by Rambus, Inc.

RAMDAC

Acronym for random-access memory digital-to-analog converter.

RAW

Unprocessed. The term refers to data that is passed along to an I/O device without being interpreted. In contrast, cooked refers to data that is processed before being passed to the I/O device.

It often refers to uncompressed text that is not stored in any proprietary format. The term comes from UNIX, which supports cooked and raw modes for data output to a terminal.

RDRAM

Acronym for Rambus DRAM. A dynamic RAM chip technology from Rambus, Inc. Direct RDRAMs are used in computers. Direct RDRAM chips are housed in RIMM modules, which are similar to DIMMs but have different pin settings. The chips can be built with dual channels, doubling the transfer rate to 3.2 GB/sec.
