A list of official certifications or compliance marks that the product has received from regulatory bodies, safety organizations, or industry standards groups. Each entry represents a distinct certification such as CE, FCC, RoHS, UL, or WEEE, and may include additional details like version numbers or specific test reports.

A list of operating system names and versions that the product can run or support, including specific architectures when relevant. Each value represents a distinct OS that is compatible with the hardware or software.

A comma‑separated list of the LED colors or models used in a product’s connectivity indicators, such as AA, CD, RD, SD, TR, CS, ARQ/FAX. The value describes which LED types are present on ports or status lights that signal network activity or power state.

The physical or logical interface used by a device to connect with other components, such as USB, PCI Express, SATA, Ethernet, Thunderbolt, DisplayPort, or similar standards. It indicates the technology that enables data transfer and power delivery between the product and its peripherals.

A concise list of the minimum hardware, software, and firmware specifications required for a product to operate correctly. Each requirement is expressed in plain language and may include operating systems, processor types, memory size, storage capacity, graphics capabilities, or other relevant components. The list helps users verify that their environment meets the essential criteria before purchasing or installing the product.

The maximum data transfer rate that a modem can achieve, expressed in kilobits per second (Kbit/s) or other common abbreviations such as Kbps. This value represents the theoretical peak throughput of the device under optimal conditions and allows users to compare the speed capabilities of different modems.

The range of relative humidity, expressed as a percentage, within which the product is designed to operate reliably when it is not actively conditioning or condensing moisture. Values are given as a minimum–maximum interval such as "5 - 95 %" and indicate the acceptable environmental moisture level for optimal performance during non‑operating conditions.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

The type of electrical supply used by the product, such as AC mains, DC power, USB power, battery, or a combination of these options.

The range of temperatures in which a device can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

A list of network or communication protocols that a device can use, such as TCP/IP, HTTP, FTP, DHCP, DNS, and various wireless standards. Each protocol is represented by its standard name and may be separated by commas or slashes in the source data.

The mass of the product expressed in a standard unit such as grams or kilograms. It represents how heavy the item is and can be used for shipping calculations, handling instructions, or consumer information.

The mass of a product expressed in pounds (lbs). It represents how heavy the item is and can be used for shipping calculations, handling instructions, or consumer information.
