Corrections to the text are provided as I become aware through continuing research or reader input. The book and website are collaborative.

Correction one: I made several typographic errors in the text regarding the speed of CPUs in GHz (gigahertz) that will be corrected in the first online revision scheduled for March 30 2015. In the meantime... A Core i7-5930K CPU runs at about 3.5GHz under load unless overclocked to, perhaps 4.0GHz or 4.4GHz. In Windows 10, right click on the Start button select Device Manager and Select Processors within Device Manager to see the installed CPU and its rated speed in GHz. Almost all available CPUs run within a range of 2.0 to 5.0 GHz. Of course, GHz is only one indicator of CPU power, number of cores, threads per core and the size of onboard (L1, L2 and L3) caches also influence CPU speed.

Addition one: Beware of small HTML sockets found on some PC components, including monitors. An HTML socket may look like a mini or micro HTML socket but actually be a MHL (micro USB for phone or tablet) socket. HDMI plugs come in the standard Type A (Regular) we often see in Big Box retail stores and the Type C (mini - 10.42mm X 2.42mm) and Type D (micro - 6.4mm X 2.8mm). Forcing a Type C or D plug into a MHL socket is bad...very bad and will destroy the socket.
