Introduction to Computing ­ CS101
VU
LESSON 1
INTRODUCTION
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:
It could analyze up to 300 billion chess moves in
three minutes
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
Goals for Today:
To develop an appreciation about the capabilities of computing
To find about the structure & policies of this course

Reading Assignments
Please make sure to read the assigned material for each week before the commencement of the
corresponding week
Reading that material beforehand will help you greatly in absorbing with ease the matter
discussed during the lecture
Check your e-mail often for announcements related to this and other VU courses
Marks distribution ...
Assignments (15%)
Almost one every week, 13 in all
No credit for late submissions
The lowest 2 assignment grades will be dropped
Midterm Exam (35%)
During the 8th week
Duration: One hour
Will cover all material covered during the first seven weeks
Final Exam (50%)

exam
Duration: 2 hours
First Assignment
Send an email message to me at altaf@vu.edu.pk with the subject "Assignment 1" giving me some
information (in around 50 words) about what you see yourself doing ten years from now
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
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
