How to install Dmidecode in OpenSUSE Leap 42.3

To use dmidecode in OpenSUSE Leap 42.3

dmidecode also refereed as the Desktop Management Interface, is a very useful tool for finding out information related to your system  hardware. dmidecode dumps your computer' s DMI (SMBIOS) table contents in a human-readable format, and it does not scan the system for this purpose. The information covered by dmidecode includes model name, serial number, BIOS version, asset tag and other details depending on the manufacturer. It is important to note that, the dmicecode should be run only as a root user. Installing dmidecode is as simple as using it, and this article covers the method to install dmidecode on OpenSUSE Leap 42.3
