Raspberry Pi is a single-board computer (SBC) that originally released in 2012 and has received several revisions since with increasingly powerful hardware. Its main drawcard is that it is a very small computer that is still capable of running full Linux workloads, albeit with minimal CPU power.
I own two Raspberry Pis, one each of the original and second revisions. Some things I’ve used them for includes:
They’re pretty handy computers and are a good way to get an introduction to Linux usage if you’re not familiar, since there are lots of guides for doing just about anything on a Raspberry Pi.
You can of course check out the official Raspberry Pi website for more info if you like.
