CS101 Introduction to Computing

Lecture 1Introduction

Page 2: My lectures

Every minute dies a man,Every minute one is born

Alfred Tennyson(very famous poet)

Page 3: My lectures

Every minute dies a man,And one and sixteenth is born

Charles Babbage(very famous computer scientist)

Page 4: My lectures

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)

Page 5: My lectures

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

Page 6: My lectures

Ada, Countess of Lovelace(1815-52)

• Babbage: the father of computingAda: 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

Page 7: My lectures

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.

Page 13: My lectures

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

And now a question …

It could analyze up to 300 billion chess moves in three minutes

First AssignmentA. Send an email message to me at [email protected] with the

subject “Assignment 1” giving me some information (in around 50 words) about what you see yourself doing ten years from now

B. Go to the CS101 message board and post a message (consisting of approx. 50 words) about how we could make the contents of this course more suitable for your individual needs. The subject for this message should be “Assignment 1”

Consult the CS101 syllabus for the submission deadline

Page 57: My lectures

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

Page 58: My lectures

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

– the structure and contents of CS101

Page 59: My lectures

In the Next Lecture …

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
