II Start of IT and the History of Computing
If you are very familiar with
PCs (personal computers) you can safely skip the history
lesson. Fair warning that skipping yesteryear data will deprive
you of the data for some fun bets you are sure to win (unless
the opposing party has also read this book J.
Data you really need to know
begins with the Success Owl regarding 8-bit vs. 16-bit
data paths. If that sounds like Greek to you, then it is important to
read the history lesson.
You will learn the different
ways computer manufactures offered expansion capabilities
to their hardware.
After examining the sub systems
that are the parts of the PC you will learn the principles
of electricity. Building on your newfound understanding of electricity,
you will discover how electronic components behave and
how to visually Identify them. Visual explanations augment
Finally, you will garner an understanding
of how Base2 (binary) math relates to both Base10
(everyday math) and Base16 (hex) math, without
needing to be a propeller head.
Many consider the first computer to be an invention by the American known as Herman Hollerith. This machine read punch cards, to tie the latest statistics for the 1890 census. (He got the idea from his brother back in Europe, when reading his letter about the new weaving looms operated.) Hollerith sold the US Congress on the idea. (Computing first vaporware product) The 1890 Census was completely done in months, not years. And distilling data such as how many wheat farmers live in Ohio? became feasible. Hollerith was a smash hit. Later, financial difficulties forced the sale of this machine to a firm known as Computer Tabulating Recording (CTR). A former salesman of player pianos at the time was Thomas Watson, who was working with CTR. Eventually, Watson took over the company, renaming it IBM.
