HP Abbreviation Glossary

	A - D
	ADP (Accidental Damage Protection) - A hardware support agreement covering physical damage to a product caused by or resulting from a fortuitous incident. Accidents covered include liquid spills, drop impact, electrical surges, and accidental breakage. Damaged notebook LCDs are included. A part damaged by accident can be replaced once per year. Defective parts are covered by the standard product warranty. Theft, fire, and normal wear and tear are not covered. BL (BLade Server) - An HP brandname for ProLiant BladeServers, which are designed for the performance, management, density and total cost of ownership (TCO) savings requirements of data centers. DDR2 (Double Data Rate) - DDR2 RAM is an improved version of DDR memory that is faster andmore efficient which give the RAM more bandwidth. DDR2 memory can send data on both the rising and falling edges of the processor's clock cycles, nearly doubling the amount of work the RAM can do in a given amount of time. DDR and DDR2 are also both types of SDRAM, which allows them to run faster than conventional memory. DDR2 memory is not compatible with standard DDR slots. DDS (Digital Data Storage) - The technology that allows binary information to be recorded to a 4mm DAT. The drive mechanism uses 4 heads - two to write and two to read. The tape makes contact with the heads at a 90 degree angle to produce an angled track known as a helical scan. DDS is a series of recording formats that allow DAT to be used for the storage of data. Each DDS format is backwards compatible and builds upon the preceding format’s features. DDS formats include DDS-1, DDS-2, DDS-3, and DDS-4. DIMM (Dual Inline Memory Module) - A series of Random Access Memory (RAM) chips mounted on a small printed circuit board. The entire circuit collectively forms a memory module. DIMMs are commonly used in personal computers, servers and high-end workstations. The DIMM makes physical contact with the data bus of the computer through teeth like connectors that fit into a socket on the mother board. DL (Density Line) - An HP brandname for the ProLiant Density Line, which are servers in one-, two- and four-socket designs, optimized for rack-mounted server environments. DLT (Digital Linear Tape / Super Digital Linear Tape) - A magnetic tape technology that uses half-inch, single-hub cartridges, writes 128 or 208 linear tracks, and provides capacities from 40 to 80GB. DVI (Digital Visual Interface) - A digital interface to a digital display system that uses TMDS signaling. The DVI interface is used on flat panel displays, data projectors, plasma displays, digital TVs (DTVs) and set-top boxes. DVI devices may include HDCP encryption for safeguarding copyrighted material. To accommodate computers with analog display adapters, DVI connectors are made to support analog and digital signals from the computer to the monitor using one socket DVI-I (Integrated with DVI-A and DVI-D plugs). DVI-A: the plug for analog to digital. DVI-D: the plug for digital to digital signal DVI-D (Digital Visual Interface) - A digital interface to a digital display system that uses TMDS signaling. The DVI interface is used on flat panel displays, data projectors, plasma displays, digital TVs (DTVs) and set-top boxes. DVI devices may include HDCP encryption for safeguarding copyrighted material. To accommodate computers with analog display adapters, DVI connectors are made to support analog and digital signals from the computer to the monitor using one socket DVI-I (Integrated with DVI-A and DVI-D plugs). DVI-A: the plug for analog to digital. DVI-D: the plug for digital to digital signal. Top

	E - I
	ECC (Error Correcting Code memory) - A memory technology that automatically tests for and corrects memory errors automatically, often without the operating system being aware of it, or the user. As data is written into memory, ECC-enabled circuitry within the RAM generates so-called “checksums” from the binary sequences in the bytes and stores them in an additional seven bits of memory for 32-bit data paths or eight bits for 64-bit pathways. When data are retrieved from memory, the checksum is then re-constituted to determine if any of the stored data bits have been corrupted. EVDO (Evolution Data Only/Evolution Data Optimized) (often abbreviated as EVDO, EV-DO, EvDO, 1xEV-DO, 1xEvDO) - Provides fast wireless broadband 3G internet service to your lap via pcmci slot. You can take the internet with you in your car, airport, train, anywhere your service provider supports in order to surf the web at your convenience. FBD (Fully Buffered DIMM) - Fully Buffered DIMM (or FB-DIMM) is a memory technology which can be used to increase reliability, speed and density of memory systems. Conventionally, data lines from the memory controller have to be connected to data lines in every DRAM module. As memory width, as well as access speed, increases, the signal degrades at the interface of the bus and the device. FSB (Front Side Bus) - (Also called System or Host Bus) The bus or pathway within a computer that connects the processor with main memory and runs at 266, 333, 400, 533, or 800 MHz or faster depending on the processor and chipset used. GMA (Gmail Drive) - A free shell namespace extension ("add-on") for Microsoft Windows Explorer, makes it possible to create a new network share on the workstation. In order to use this add-on, you need a Gmail account from Google Gmail. The add-on enables you to use the normal Windows desk file copy and paste commands to transfer files to and from your Gmail account just as if it was physically located on your local network. ICA (Independent Computing Architecture) - A proprietary protocol for an application server system, designed by Citrix Systems. The protocol lays down a specification for passing data between server and clients, but is not bound to any one platform. IEEE (Institute of Electrical and Electronics Engineers) - This group is a U.S. based standards organization that establishes standards for the data communications industry, especially for LANs. Top

	J - N

This means that different manufacturers’ tapes and tape drives will interoperate (just as audio tape cassettes work in all audio tape players). ML (Modular Line) - An HP brandname for the ProLiant Modular Line, which is an expandable tower. Rack/tower options are available in one- and two-socket, entry and enterprise-class feature sets. MSA (Modular Smart Array) - Uses existing linear multi-channel bi-directional tape format. NCQ (Native Command Queuing) - A technology designed to increase performance of SATA hard disks under certain situations by allowing the individual hard disk to internally optimize the order in which received read and write commands are executed. Non-ECC (Non-Error Checking and Correcting) - The memory is not doing any of the ECC function. ECC-RAM is a type of main memory that is designed to test the accuracy of data as it passes in and out of main memory. The circuitry generates checksums to correct errors greater than 1 bit. It is possible to mix ECC RAM and Non-ECC RAM, but the memory error checking (or ECC function) and correcting function will be disabled. Top

	PCI (Peripheral Component Interconnect) - The PCI bus is a 32 or 64-bit local bus designed by Intel, which runs at 33 MHz or 66 MHz and supports Plug and Play connection. Penryn Brand of Intel processor RAID (Redundant Array of Independent Disks) - A hard-drive technology that is used to increase general storage performance, provide fault tolerance, or both. In RAID, two or more hard-drives work in combination to provide increased performance and various levels of error recovery and fault tolerance. RAID can be implemented via hardware or software. Hardware RAID requires a specific RAID disk controller. Software RAID requires operating system software support and standard disk controllers. The primary drawback to software RAID is that it is CPU intensive and does not provide an automatic rebuild of information. Hardware RAID is preferable because it provides better performance, more efficient use of system resources, and automatic rebuild of data. RAID 1 was the first real implementation of RAID. It provides a simple form of redundancy for data through a process called mirroring. RAID 0+1 - This is a hybrid form of RAID that some manufacturers have implemented to try and give the advantages of each of the two versions combined. Typically this can only be done on a system with a minimum of 4 hard drives. RAID 10 is effectively a similar version to RAID 0+1. Rather than striping data between the disk sets and then mirroring them, the first two drives in the set are a mirrored together. The second two drives form another set of disks that is are mirror of one another but store striped data with the first pair. RAID 5 - This is the most powerful form of RAID. This method uses a form of striping with parity to maintain data redundancy. A minimum of three drives is required to build a RAID 5 array and they should be identical drives for the best performance. RDP (HP) (Router Discovery Protocol) - A standard protocol, to inform hosts of the presence of routers to which they can send packets. You can also use RDP instead of host wiretapping routing protocols (for example, RIP). It is used instead of, or in addition to, having statically configured default routes in hosts. RDP (Microsoft) (Remote Desktop Protocol) - A remote display and input capabilities over network connections for Microsoft Windows-based applications running on a server. RDP is designed to support different types of network ologies and multiple LAN protocols. RoHS (Restriction of Hazardous Substances) - The RoHS directive has been adopted by the European Union. RoHS restricts the use of six hazardous substances: lead (Pb), mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE) in all electrical and electronic products, and their component parts, offered for sale beginning July 1, 2006 in Europe and January 1, 2007 for California.

	SAN (Storage Area Network) - A high-speed network that connects multiple storage devices so that they may be accessed on all servers in a Local Area Network (LAN) or Wide Area Network (WAN). SAS (Serial Attached SCSI) - A replacement for the Parallel SCSI physical storage interface. Serial Attached SCSI offers much faster communication and easier configuration. In addition, Serial Attached SCSI provides device compatibility to Serial ATA and uses similar cabling. SATA (Serial Advanced Technology Attachment) - Advanced Technology Attachment (ATA), also known as AT attachment or AT attachment Packet Interface (ATAPI), is a standard interface for connecting storage devices such as hard disks and CDROM drives inside personal computers by using a single cable with a minimum of 4 wires creates a point-to-point connection between storage devices. Many terms and synonyms for ATA exist, including abbreviations such as IDE, ATAPI, and UDMA. ATA standards only allow cable lengths up to 18 inches (up to 450 mm) although cables up to 36 inches (900 mm) can be readily purchased, so the technology normally appears as an internal computer storage interface. It provides the most common and the least expensive interface for this application. SDRAM (Synchronous Dynamic Random Access Memory) - A type of high-speed DRAM that can transfer bursts of non-contiguous data at 100 MB/second or greater and works with up to 100 MHz processor speeds. This technology uses a clock to synchronize signal input and output on the memory chip. The clock is coordinated with the CPU clock so the timing of the memory chips and the CPU are “in sync.” SDRAM can increase overall system performance by reducing time to execute commands and transmit data. Its two internal banks allow one bank to get ready for access while the other bank is being accessed. These features eliminate performance bottlenecks when sending data from main memory to the system processor. Since SDRAM works differently than FPM or EDO RAM, its specification is measured in processor speed (MHz) rather than just access time (nanoseconds). SDVO (Serial Digital Video Output) - Makes it possible to use a 16-lane PCI express slot to add additional video signaling interfaces such as VGA and DVI monitor outputs, SDTV and HDTV television outputs, or TV tuner inputs to a system board containing an integrated Intel 9xx-series graphics processor. SFF (Small Form Factor) - A device that is smaller than others in its field. SODIMM (Small Outline-DIMM) - A DIMM module with a thinner profile due to the use of thin small outline chip packages (TSOP). SODIMMs are commonly used in laptop computers. SQL (Structured Query Language) - A language used to create, maintain, and query relational databases. It is an ISO and ANSI standard. SQL uses regular English words for many of its commands, which makes it easy to use. It is often embedded within other programming languages. TPM (Trusted Platform Module) - A component on the PC motherboard that is specifically designed to enhance platform security above-and-beyond the capabilities of today’s software. Defined by the Trusted Computing Group’s public specification, the TPM provides hardware-based protection for the encryption and digital signature keys that secure your data’s confidentiality. The TPM also provides a hardware-based authentication mechanism that strengthens existing network-access controls. ULV (Ultra Low Voltage) - A class of processors that are deliberately under clocked to use less power at the expense of performance. This reduces the heat produced, and extends battery life, and so ULVs are often seen in subnotebooks, netbooks, ultra portables and embedded devices. UMA (Unified-Memory Architecture also called Shared Memory Architecture) - Allows the CPU and video controller to share the same main memory and 64 bit data path. One or two MB of main memory is allocated to video via a Win 95 utility or in the PCs setup. For best system performance, uses 1 MB for text and 2 MB for graphics applications. HP and video chip manufacturer SiS collaborated on the implementation of UMA via hardware, so it is OS independent. USB (Universal Serial Bus) - USB was designed to allow many peripherals to be connected using a single standardized interface socket and to improve the plug-andplay capabilities by allowing hot swapping, that is, by allowing devices to be connected and disconnected without rebooting the computer or turning off the device. VDI (Virtual Desktop Infrastructure) - An end-to-end client virtualization solution based on the best managed and virtualization-ready HP ProLiant and BladeSystem servers, HP StorageWorks storage, and HP Thin Client access devices. VESA (Video Electronics Standards Association) - An organization to help standardize how PCs implement video technologies. The first standard this organization created was the 800x600 pixel Super VGA (SVGA) display and its software interface. It also defined the VESA Local Bus (VL Bus). VGA (Video Graphics Array) - A resolution displayed on a monitor of 640 x 480 pixels. Also refers to a 15-pin video graphics port on a PC. VIA (Product of VIA Technologies) - A chipset/processor used in the 2133 Mini and 2533t Mobile Thin Client. vPRO (Intel® vPro™ Technology) - Notebook and desktop PCs with Intel® vPro™ technology enable IT to take advantage of hardware-assisted security and manageability capabilities that enhance their ability to maintain, manage, and protect their business PCs. And with the latest IT management consoles from Independent Software Vendors (ISVs) with native Intel vPro technology support, IT can now take advantage of enhanced features to manage notebooks over a wired or corporate wireless network- or even outside the corporate firewall through a wired LAN connection. WEEE (Waste Electrical and Electronic Equipment) - European Union directive (2002/96/EC) making manufacturers responsible for financing the recycling of end-of-life equipment. The law differentiates between historic waste (a product put on the market before August 13, 2005) and new waste (a product put on the market after August 13, 2005). WPLO (Warranty Parts/Labor/Onsite) - There are three components of HP Standard Warranty, specifically Parts, Labor and Onsite. There are variations depending on the model, e.g. some models include 1/1/1 (One year Parts, One year Labor, One year Onsite) or 3/3/0 (Three years Parts, Three years Labor and no onsite; pick up and return only). HP Care Packs can be purchased to extend the basic Parts/Labor/Onsite beyond standard warranty coverage. WSVGA (Wide Super Video Graphics Array or Wide Ultra Video Graphics Array) - WSXGA and WXGA+ are non-standard terms referring to computer display resolutions. Usually, WSXGA+ refers to a resolution of 1680x1050, while WXGA refers to a resolution of 1440x900, but occasionally manufacturers use the terms to refer to other resolutions. WSXGA and WXGA+ can be thought of as enhanced versions of WXGA with more pixels, or as widescreen variants of SXGA. The aspect ratios of each are 16:10 (widescreen). The panel resolutions used are: WXGA, WXGA+, WSXGA+, WUXGA.
