In computing, the System Management BIOS (SMBIOS) specification defines data structures (and access methods) that can be used to read management information produced by the BIOS of a computer. [1] This eliminates the need for the operating system to probe hardware directly to discover what devices are present in the computer.
dmidecode is a free userspace command-line utility for Linux that can parse the SMBIOS data. [2] [3] The name dmidecode is derived from Desktop Management Interface, a related standard with which dmidecode originally interfaced.
Thus, for variant 1 (that is, most UUIDs) a random version 4 UUID will have 6 predetermined variant and version bits, leaving 122 bits for the randomly generated part, for a total of 2 122, or 5.3 × 10 36 (5.3 undecillion) possible version-4 variant-1 UUIDs. There are half as many possible version 4, variant 2 UUIDs (legacy GUIDs) because ...

DMI exposes system data (including the System Management BIOS (SMBIOS) data) to management software, but the two specifications function independently. DMI is commonly confused with SMBIOS, which was actually called DMIBIOS in its first revisions.
A unique identifier (UID) is an identifier that is guaranteed to be unique among all identifiers used for those objects and for a specific purpose. [1] The concept was formalized early in the development of computer science and information systems.
Discovery of access points is a two phase process: Phase 1: an RMCP Presence Ping request is sent (broadcast, multicast or unicast) and an RMCP Presence Pong response is received indicating support for WS-Management.
A UUID is defined as an array of bytes that is intended to be unique in the Universe. Note that these are not limited to the standards for ISO, Microsoft, or DCE UUIDs though those are examples of acceptable sources of UUIDs. Attribute names are case-folded and normalized strings of Unicode characters
