10. Charles Babbage
Difference Engine - 1822
• Execute
simple
calculations
by changing
gears.
• The first form
of computer
language
was physical
motion.

11. Eniac - 1942
• Physical motion was replaced by electrical signals
• Followed same principles of Babbage’s engine
• Programmed by presetting switches and rewiring
the entire system for each new calculation

12. Jon Von Neumman - 1945
1. Computer hardware should be simple and able
to read complex instructions
2. Use small blocks of code that could be jumped
to in any order instead of chronologically
IF THEN FOR

13. Fortran – 1957
FORmula TRANslating system
IF DO GOTO
TRUE / FALSO

14. Cobol – 1960
COmmon Business Oriented Language .
Numbers Input /Output

15. ALGOL – 1958
ALGOrithmic Language
PASCAL
C
JAVA
C++

16. C PROGRAMMING - 1972
• Dynamic arrays and group of variables
not included in Pascal led to its downfall
• Fast and powerful but harder to read
• Developed for UNIX
• UNIX gave advantages to C:
multitasking, forking, dynamic variables, interrupt
handling and strong low-level input / output
• Commonly used to program operating systems as:
UNIX, Windows, OS and Linux

17. Object Oriented
Programming
• Objects are pieces of data
• Extensions created called “C with Classes”
C++
• Same speed as C
• Able to run in many computers
• Hundreds of instances simultaneously

18. Java
• Interactive TV lead to create
Java by Sun Microsystems
• Netscape: first licensed
browser
• Serious optimization
problems and programs
written ran very slowly

19. Compilation
