The document discusses the history of computing and software development. It describes Charles Babbage as the inventor of the first mechanical computer in the 19th century. It then discusses Ada Lovelace, who wrote the first computer program for Babbage's Analytical Engine. Finally, it covers Alan Turing and his work in developing the Turing machine and breaking the Enigma code during World War 2, laying the foundations for modern computing.

6. The father of computer
- Born in London on 26 December 1791.
- Died18 October 1871 (aged 79).
- Invented the first mechanical computer.
- A mechanical computer is built from mechanical components
such as levers and gears, rather than electronic components.
- The essential ideas of modern computers are to be found in
Babbage's analytical engine.

made to compute values
Analytical Engine (1837)
created to calculate a series of values
automatically

9. Ada Lovelace
The first programmer of all time
- Born in London on December 10, 1815
- Died27 November 1852 (aged 36)
- In 1953, more than a century after her death, Ada Lovelace's
notes on Babbage's Analytical Engine were republished. The
engine has now been recognised as an early model for a
computer and her notes as a description of a computer and
software.

10. Ada Lovelace
Ada Lovelace's notes were labelled alphabetically
from A to G

12. - World War || - From 1939 to 1945
- Hut 8 was a section in the Government Code and
Cypher School (GC&CS) at Bletchley Park.
- Hut 8 was responsible for German naval
cryptanalysis.
- Enigma was invented by the German engineer
Arthur Scherbius at the end of World War I
- The Enigma machines were a series of
electro-mechanical rotor cipher machines
developed to protect commercial, diplomatic and
military communication.

14. Alan Turing
The first software Developer
- Born in London on 23 June 1912
- Died7 June 1954 (aged 41)
- Provided a formalisation of the concepts of algorithm and
computation with the Turing machine.
- During the Second World War, Turing worked for the
Government Code and Cypher School (GC&CS).
- He invented Turing machine (1936) which is a mathematical
model of computation
- There is a movie about his life called “The Imitation Game”
