Who is Charles Babbage, what did he do

and how has he affected the realm

of Information Systems. Where do you see his

influence today?

“Father of Computing"

Who was he?

(1791 - 1871)

- Mathematician, - Inventor - Philosopher - Mechanical engineer

Biography Charles Babbage

1791 - was born on 26 December, London, England 1814 - married Georgina Whitemore at the age of 23, 1827 – Wife died at the age of 35 1832 - published "Economy of Manufactures and Machinery" 1842 - published "Sketch of the Analytical Engine" 1864 - published "Passages from the Life of a Philosopher" 1871 - died on 18 October in London, England

1816 - Founded the Astronomical Society 1820 - Founded the Analytical Society 1821 - Began work on the Difference Engine 1827 - Published a table of logarithms from 1 to 108000 1832 - British government suspended funding for his

Difference Engine 1834 - Began work on the Analytical Engine 1837 - Conceptual design for Analytical Engine completed 1842 - Begins work & designing the Difference Engine No. 2 1856 - design of the Analytical Engine completed, uses Jacquard's punch card idea for programming

Career Milestones

Difference Engine No. 1 (1821)

Calculator - to calculate a series of values and print results

automatically in a table.

Analytical Engine (1834)

General-purpose programmable computing engine

Difference Engine No. 2 (1842 - 1849)

An improved version of the original. The design was 1/3 of the parts from Difference Engine No. 1,

while providing similar computing power.

1821 “Difference Engine No.1”

Calculator (Addition & subtraction only)

1834 “Analytical Engine”

Calculator & (Addition, Subtraction,

Multiplication & division)

1842 - 1849 “Difference Engine No.2” (Improved version and a

combination of Engine No.1 & Analytical Engine)

All 3 models designs were completed however they

were physically partially completed

None of Babbage's designs was physically realized in his

lifetime - WHY?

1. Victorian mechanical engineering were not sufficiently developed to produce parts with sufficient precision. 2. Lack of funding 3. Personality Differences

Why Charles Babbage never completed his 3 engines

1821 “Difference Engine No.1”

Calculator (Addition & subtraction only)

2012 Calculators are pre-designed with specific functions such as addition,

multiplication, and logarithms built in

1842 - 1849 “Difference Engine No.2” (Improved version and a

combination of Engine No.1 & Analytical Engine)

2012 A computer is a programmable machine

designed to carry out a sequence of arithmetic or logical operations

- his invention has made IS possible - IS an essential and integral part of our lives that we cannot imagine a life without it

Conclusion

How has Charles Babbage invention affected the realms of information Systems?

The End,

Thank You
