====== Ubuntu - Hardware - dmidecode ======

**dmidecode** is a tool for dumping a computer DMI (some say SMBIOS) table contents in a human-readable format.

This table contains a description of the system hardware components, as well as other useful pieces of information such as serial numbers and BIOS revision.

The **DMI** table does not only describe what the system is currently made of, it also can report the possible evolutions (such as the fastest supported CPU or the maximal amount of memory supported).

SMBIOS stands for System Management BIOS, while DMI stands for Desktop Management Interface. Both standards are tightly related and developed by the DMTF (Desktop Management Task Force).
