Introduction to Computing
1.1. Charles Babbage (1791-1871)
Creator of the Analytical Engine - the first general-purpose digital computer (1833)
The Analytical Engine was not built until 1943 (in the form of the Harvard Mark I)

1.2. The Analytical Engine
A programmable, mechanical, digital machine
Could carryout any calculation
Could make decisions based upon the results of the previous calculation
Components: input; memory; processor; output

1.3. Ada, Countess of Lovelace(1815-52)
Babbage: the father of computing
Ada: the mother?
Wrote a program for computing the Bernoulli’s sequence on the Analytical Engine - world’s 1st
computer program
Ada: A programming language specifically designed by the US Dept of Defense for developing military
applications was named Ada to honor her contributions towards computing

A Lesson that we all can learn from Babbage’s Life
Charles Babbage had huge difficulties raising money to fund his research
As a last resort, he designed a clever mathematical scheme along with Ada, the Countess of Lovelace
It was designed to increase their odds while gambling. They bet money on horse races to raise enough
money to support their research experiments
Guess what happened at the end? The lost every penny that they had.
Fast
Bored
Storage
Here is a fact
:
In 1997 Deep Blue, a supercomputer designed by IBM, beat Gary Kasparov, the World Chess
Champion
That computer was exceptionally fast, did not get tired or bored. It just kept on
analyzing the situation and kept on searching until it found the perfect move from its list of possible moves

A suggestion about unfamiliar terms
We try not to use any new terms without explaining them first
However, it is not possible to do that all the time
If you encounter any unfamiliar terms during the lectures, please note them down and consult the
GLOSSARY provided at the end of the “Understanding Computers” text book for their meaning

Let’s summarize the things that we have covered today?
A few things about:
the very first digital computer & its inventor
the capability of modern computers

In the Next Lesson …
We’ll continue the story of the evolution of digital computers form the Analytical Engine onwards.
We’ll discuss many of the key inventions and developments that he lead to the shape of the current field
of computing.
