HP ProOne 440 G3 (23,8″)

Size of the display for this product, measured diagonally, usually in inches.

The number of distinct pixels in each dimension that can be displayed. It is usually quoted as width × height, with the units in pixels: for example, “1024 × 768” means the width is 1024 pixels and the height is 768 pixels. The higher the number of pixels, the sharper the image.

A screen of a laptop, smartphone, etc., that responds to touch so you can control the interface using your fingers.

Type of supported High Definition (e.g. Full HD, 4K Ultra HD).

A backlight is a form of illumination used in liquid crystal displays (LCDs). One type of backlight is made by LEDs, which can be either white or RGB (red green blue). White LEDs are used most often in notebooks and desktop screens, and in virtually all mobile LCD screens. RGB LEDs for backlighting are found in high-end color proofing displays such as HP DreamColor LP2480zx monitor or selected HP EliteBook notebooks, as well as newer consumer grade displays such as Dell’s Studio series laptops which have an optional RGB LED display.

The aspect ratio is the ratio of the width of an image to its height. The native aspect ratio is the one which the projector/display is particularly designed for. Images shown in native aspect ratio will utilize the entire resolution of the display and achieve maximum brightness. Images shown in other than native aspect ratio will always have less resolution and less brightness than images shown in native aspect ratio.

The manufacturer that produced the processor.

A family of processors is a group of processors produced by one company over a short period of time e.g. Intel Pentium processors.

The model number for the processor in a computer.

The number of central processing units (‘cores’) in a processor. Some processors have 1 core, others have 2 (e.g. Intel Core Duo) or more (e.g. the Intel Xeon E7-2850 has 10 cores).

The speed that the microprocessor executes each instruction or each vibration of the clock. The CPU requires a fixed number of clock ticks, or cycles, to execute each instruction. The faster the clocks rate, the faster the CPU, or the faster it can execute instructions. Clock Speeds are usually determined in MHz, 1 MHz representing 1 million cycles per second, or in GHz, 1 GHz representing 1 thousand million cycles per second. The higher the CPU speed, the better a computer will perform.

A bus is a communication system that transfers data between components inside a computer, or between computers. The system bus rate is the speed at which data is transferred in this communication system.

Mechanical component(s) that provides mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows the processor to be replaced without soldering.

The process which is performed by the processor e.g. CPU (Central Processing Unit).

Operating modes for the processors that place restrictions on the type and scope of operations for certain processes run by the CPU. This design allows the operating system to run with more privileges than application software.

“Conflict free” means “DRC conflict free”, which is defined by the U.S. Securities and Exchange Commission rules to mean products that do not contain conflict minerals (tin, tantalum, tungsten and/or gold) that directly or indirectly finance or benefit armed groups in the Democratic Republic of the Congo (DRC) or adjoining countries.

A computer’s memory which is directly accessible to the CPU.

The type of internal memory such as RAM, GDDR5.

The maximum internal memory which is available in the product.

Number and type of memory expansion slots, including connector and memory module descriptions.

A memory slot, also known as a memory socket or RAM slot, is what allows computer memory (RAM) to be inserted into the computer. Depending on the motherboard, there will usually be 2 to 4 memory slots (sometimes more on high-end motherboards). The most common types of RAM are SDRAM and DDR for desktop computers and SODIMM for laptop computers, each having various types and speeds.

The frequency at which the memory (e.g. RAM) runs.

The slots and size of the memory for the CPU.

Design of the memory e.g. 240-pin DIMM, SO-DIMM.

The total amount of data that can be stored on the device.

Used for the storage of data e.g. HDD (hard disk drive), SSD (solid-state drive).

The number of hard drives built into the device.

The maximum storage capacity of the hard disk, usually measured in bytes e.g. GB.

The rotational speed of a hard disk expressed in rotations per minute. The faster the better.

The way that a hard disk drive (HDD) is connected to the rest of the computer through a ‘bus’ such as ATA or SCSI.

An optical drive uses laser to read optical discs such as CDs, DVDs and Blu-Ray. Some types of optical drive are: CD ROM drive, CR-RW (CD writer) drive, DVD-ROM.

A card reader is a device that enables reading and, in some cases, writing data to and from a memory card.

Types of memory cards which can be used with this product.

A graphics adapter (often known as a video card) generates images for a display. A discrete graphics adapter plugs into the motherboard, and usually produces much better graphics than an integrated graphics adapter. There are various models of discrete graphics adapters.

Graphics hardware which is built into the motherboard or CPU, as opposed to a separate graphics adapter (video card). On-board graphics uses CPU and RAM for graphics processing.

“Graphic adapter” is the hardware that produces images on a display. “On-board” means that the graphics adapter is intergrated inside the motherboard.

The feature may not be available on all computing systems. Functionality, performance, and other benefits of this feature may vary depending on system configuration.
