Jeff Grisso ( AKA sonic840 on deviantart) has been maintaining and updating for some years a poster of nearly all PC hardware one would encounter. He just published an update (7 years in the making) of this work. This update is HUGE! The scaled version I have uploaded does not do this work justice.
If you find yourself wondering “what is this socket or computer thing?”. I would start here. Its hard to ask the right question or search for details if one is not familiar with what something is called.
You can grab a copy of the poster here.
And PLEASE, support Jeff’s work!
