The vertical dimension of a product measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.

The impedance value indicates the resistance that a component or circuit offers to alternating current, expressed in ohms (Ω). It is used to characterize speakers, microphones, audio cables and other electronic equipment to ensure optimal compatibility with the source signal.

The type of LED backlighting used in a display panel, such as Direct‑LED, Edge‑LED, Full‑Array or other LED configurations. It indicates how the light source is arranged behind the screen to provide illumination and uniformity.

Indicates whether a user manual—physical or digital—is provided with the product. A value of "Yes" means that a manual is included, while a value of "No" indicates that no manual is supplied.

The range of altitudes (in meters) at which a product or component can operate reliably without performance degradation due to changes in atmospheric pressure, temperature, or other altitude‑related effects.

Indicates the preferred or supported orientation of a product, such as landscape, portrait, horizontal/vertical, or other directional settings. This attribute helps users understand how the device can be positioned for optimal use.

The linear measurement from front to back or top to bottom of a product’s packaging, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the packaged item is and can be used for fitting, compatibility, or spatial planning.

The vertical dimension of a product’s packaging measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and helps customers assess how tall the package will be when stored or shipped.

The horizontal measurement of a product’s packaging, expressed in a linear unit such as millimetres or inches. It indicates how wide the package is from one side to the other and helps customers assess fit for storage, shipping, or display.

The pair of horizontal and vertical dimensions in millimetres that a product supports for VESA mounting (e.g., "100 × 100 mm"). This value indicates the exact hole spacing required by a mounting bracket to secure the device. It is used for monitors, TVs, projectors and other display equipment that can be wall‑mounted or attached to stands.

The purpose indicates the primary function or intended use of a product, such as "Notebook", "Gaming", or "Server". It helps customers quickly identify whether the item matches their needs and can be used for filtering or categorization across different product categories.

The root‑mean‑square (RMS) power rating of a device, expressed in watts (W). It represents the average electrical power that the product can deliver or consume under normal operating conditions.

Indicates whether the product includes an RS‑232C serial port, a standard communication interface used for connecting and controlling electronic devices.

Indicates whether a device has a touchscreen interface that can detect touch input. The value is "Yes" if the device includes a functional touchscreen, and "No" otherwise.
