The History Of Programming

#learning #raja

1. Before Computers

Humans wanted machines to perform calculations automatically

1642 – Blaise Pascal built a mechanical calculator called the Pascaline
1673 – Gottfried Wilhelm Leibniz improved mechanical calculation machines

2. Programmable Machine Idea

1804 – Joseph Marie Jacquard created the Jacquard Loom
It used punched cards to control weaving patterns
This introduced the idea that a machine could follow instructions

3. Early Computer Concept

1830s – Charles Babbage designed the Analytical Engine
It was a general-purpose mechanical computer concept
It had memory, processing, and input/output ideas similar to modern computers

4. First Programmer

1843 – Ada Lovelace wrote detailed instructions (algorithms) for the Analytical Engine
She realized a machine could do more than arithmetic
Because of her notes, she is often called the first programmer

5. Foundations of Computer Science

1936 – Alan Turing proposed the Turing Machine
He showed how a machine could follow instructions to solve problems
This became a foundation of modern computing

6. First Modern Programming Languages

1957 – John Backus created FORTRAN
One of the first successful high-level programming languages

7. Popular Languages

1972 – Dennis Ritchie created C
1985 – Bjarne Stroustrup created C++
1991 – Guido van Rossum created Python
1995 – James Gosling created Java
1995 – Brendan Eich created JavaScript

My opinion

ChatGPT gives answers when questions are asked. But sometimes the origin of an answer may not be known.

We can think of three possibilities:
