The colour or combination of colours that a product’s outer shell or enclosure is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the case for consumers.

The processor family identifies the group or series of CPU models that share a common architecture, design, and performance characteristics. It helps users compare processors across brands and generations by indicating the underlying technology used in the chip.

The physical connector used by a processor to attach to a motherboard or other compatible platform, such as LGA 1151, BGA 1440, Socket AM4, or LGA 1200. This attribute indicates the exact socket designation required for proper CPU installation and compatibility with other hardware components.

The maximum operating frequency of a central processing unit (CPU), expressed in hertz (Hz). This value indicates how many cycles per second the CPU can execute under normal conditions and is useful for comparing performance potential across different models.

The specific name or designation of the central processing unit installed in a device, such as "Intel Core i5-11400" or "AMD Ryzen 7 5800X." It identifies the exact processor variant and helps users compare performance, compatibility, and features across products.

The physical size or shape of a storage disk, indicating the dimensions and mounting format used in computers and other devices. Common values include standard sizes such as "3.5" in., "2.5" in., and form‑factor codes like "M.2 2280" or "mSATA". This attribute helps users identify which drives are compatible with a given enclosure, motherboard, or system.

The form or mounting style of a hardware component, such as internal, portable, desktop, rack‑mountable, or external. It indicates how the device is physically housed and where it can be installed.

The physical or logical interface used by a hard drive to connect with other components, such as SATA, SAS, USB, PCI Express, or M.2. It indicates the technology that enables data transfer and power delivery between the device and its host system.

The amount of digital storage available in a device for holding data or program code, expressed as a data size such as megabytes (MB) or gigabytes (GB). It indicates how much information the component can hold at once and is commonly used to describe RAM modules, flash drives, SSDs, and other memory devices.

The classification of the memory technology used in a device, such as DDR4 SDRAM, LPDDR3, GDDR6, or other variants. It indicates the architecture and generation of the RAM modules installed or supported by the product.

The maximum data transfer rate supported by the network interface card, expressed in bits per second or common abbreviations such as Gbps or Mbps. This value indicates how fast the device can send and receive data over a wired connection.

The physical connection types that a PC product uses to interface with other devices or peripherals, such as HDMI, USB, Ethernet, DisplayPort, VGA, DVI, SATA, and similar cables or ports. Each value represents one distinct connector or cable type that the product supports for data transfer, video output, power delivery, or networking.

The unique model designation of a computer processor, such as "8250U" or "i7-1165G7". It identifies the specific CPU used in a device and can be compared across products to infer performance, generation, and compatibility.

Represents the total count of RJ‑45 Ethernet interfaces present on a product. Each port can accept a standard Ethernet cable for wired network connectivity.

Indicates whether the product is compatible with both USB 2.0 and USB 3.0 interfaces, allowing it to connect to devices that use either standard.

Represents how many USB connectors are available on the product. The value is a simple integer indicating the total count of USB ports, regardless of type or version.

A list of the USB interface versions that a product supports, such as USB 2.0, USB 3.0, USB 3.1, USB 3.2 or combinations like "USB 2.0 & USB 3.0". The values indicate which USB standards are available for connecting peripherals and external devices.

The length of time for which the manufacturer guarantees that the product will be free from defects in materials and workmanship, typically expressed in years or months.
