In Mountain View, California, only minutes away from Google's headquarters, is the Computer History Museum. A visit to this place is enough to show you how today's computing era began and evolved through time. If you are interested in this stuff and love history in general, you can closely examine the computers that thrived in the past and opened the door for today's modern computing systems, which can be found in almost every home. It's hard to believe that only three decades ago computers were a rare thing and very few people were lucky enough (or rich enough) to actually have one at home. However, computing technology has rapidly evolved and nowadays it is rare to find a single home without a PC or a smart device that uses a processor.
