I recently enrolled in a course of adult education classes to learn how a computer works, how to dismantle one, assemble one, load and configure any of the Windows operating systems, and troubleshoot faults. At this stage in my life it's important to keep the brain alive.
I now know how to convert decimal numbers into binary numbers, binary numbers into hexadecimal numbers, and vice versa. I can answer the question: will an electrical input into a series of Logic Gates expressed as 1 AND NOT {[0 OR (1 OR 0)] NOR [1 AND NOT (0)]} result in an output of 1 or 0.
I am sure this is stuff that most of us have always wanted to know!
The other evening we were presented with an empty computer case and a pile of small boxes containing brand new mother boards, disk drives, processors, fans, and ribbon cabling so that we could spend a riotous two hours putting the whole lot together and bolting it to the case so that it looked something like the computer we all know and love. One of my fellow classmates actually got his up and running, but I took comfort from the fact that he already had a knowledge of electronics. My own effort looks credible, but has yet to be properly wired up, so its current situation is being in a situation without current.

My brain hurt reading through all those numbers. I have a "dyslexia" with numbers, it's really painful to try and deal with just basic calculations let alone anything complex.
Dyslexadecimal!
