Definition - What does Bare-Metal Programming mean?
Techopedia explains Bare-Metal Programming
The philosophy behind bare-metal programming diverges from some of the more modern adaptations for computing. As virtualization and cloud computing take the world by storm, the specific hardware setups that programmers work on matter less and less, and coding has become, in many cases, more of an abstract application run through layers of software. By contrast, some of the most specific types of bare-metal programming, such as projects done on ARM machines like the Raspberry Pi, re-introduce the original concept that programming works in conjunction with the hardware, closer to the machine language level.
